Discovery Series 2 Engine Replacement
Watch Doug, our Land Rover Master Tech, remove and replace the engine in our 2000 Discovery Series II with one of our exclusive remanufactured engines. Doug goes in-depth in this engine installation, which in real-time should clock in as a 10 hour service. We recorded the process starting in January 2017 and finishing in November 2017, working on it when time allowed. It actually sat for months, as we had other things on our schedule to work on.
Engine Item # 9257DRK / 9257BRK Replace &Install Short Block Engine Demonstrated on 2000 Discovery Series II. Hi I'm Doug, your tech support representative here at Atlantic British. In this video we're going to touch base on what unfortunately becomes a pretty common item. As these Discovery's are getting older what's happening is we're running into head gaskets, slip sleeves, damaged cylinders due to burning coolant, a number of different things where you would end up requiring to replace the block before you;d be able to do a proper rebuild. So what we're going to do is we're going to show you essentially how to remove the engine out of a Discovery. This is a 2000. Essentially 1999 to 2004 are all going to be pretty much the same other than the 2003 and 2004 some have the secondary air that's just a little bit more involved there. But what we have here is a 2000 Discovery. The heads are already off the engine. We made a determination we have a bad cylinder sleeve. And we're going to have to rebuild and replace the block. So, we're going to show you basically what you're going to need if you want to change the engine over on your Discovery. So essentially we're going to start from underneath the vehicle. And there's a lot to unbolt when you get underneath. Main thing is going to be you have 4 bolts that attach the transmission torque converter to the flex plate. We're going to access those from an opening that's just above the starter. We're also going to be taking this little bottom plate off so we have access so we can move the torque converter. This bottom panel that sits underneath the front pulley of the engine, we'll take this out so we can put a ratchet and a socket on the lower crack pulley so we can turn the crank. That makes that easier. Starter wiring. Knock sensor wiring. We've already removed the heads off this engine so we already disconnected at the exhaust so the exhaust is floating free. You've got your 2 cooling lines that run from the transmission up front to the transmission cooler. We're going to unbolt some of that. There are some brackets on that that attach it to the engine. And the of course the bottom bolts for the back of the oil pan. And the 2 on each side above where the transmission bolts to the block. And then the other 2 we'll get to from up top. We're also going to unbolt the, probably unbolt the mounts. You've got 2 nuts on the bottom here. Some of this like the mount bolts you'll want to pre-soaking in penetrating oil before you get into to the rest. Give that a chance to work it's way in. So there's a bit to do. But it's all got to get done. It's not all that bad. It's just a little time consuming but it's nothing but nuts and bolts. All right, so, first things first. We'll start with the heat shield that surrounds the starter. And that will give us access to the 2 wires that attach to the front of the starter. The S wire and the battery cable. And what holds that on, the back of it is a snap clip, but in the front there's a little hidden bolt right up on the engine mount. Just over that plate on the inside. You're going to have to do it by feel. A 10 millimeter head bolt. And that's what attaches to the front of the heat shield to the motor mount. You need to remove that to get the heat shield out of there. So we're going to sneak up in there with a ratchet and short extension, a 10 millimeter socket, take that bolt out. so we've taken the bolt out of that shield on the round the starter as they said there's just a snap clip on there so we push outward and then come back a little bit now like I said earlier you have the battery disconnected so you don't have to worry about shorting out or touching that wire and this is gonna just sneak right out the front steering that comes right out there's the snap clip I'm talking about so you can see this just basically grabs right around the starter solenoid take that out alright so our next step is going to be to disconnect the cables off of the starter and you have one 13 millimeter nut for the battery cable and then a little what they call the S wire which is your wire which engages our solenoid just simply plugs in we can grab that with a pair of needle nose pliers and pop that out once we clear that out of the way and we've also got on the same harness the wire for the knock sensor which we're going to disconnect there and then then we can just take this part of the harness and swing that right up out of the way and then we're going to look at the couple different ways we can get at the four bolts that both the torque converter to the flex point alright so there's an access to those four bolts that hold the torque converter there's a rubber plug on the passenger side right above or right here underneath the starter and just above the offhand it's part of the back of the off pan you pull that rubber plug and you'll be able to get a direct shot at the bolts now there is a recessed in the oil pan so I usually find the best way to get at it is to use a long extension about 11 inch with a 13 millimeter side get enough ratchet and then just get in there and turn it to break it loose now to get each one to spin this I find the easiest way you take a 15 16 socket and a rat long ratchet and you get on the front pulley ball then you can just turn the engine you can turn it in either direction and if you have a little foley mirror that makes it even easier because then you can actually see up in there to be determined where the bolt is so bit of a pain but that's the way it's designed that's the best way to deal with it the only other way would be to make it any easier would be maybe to drop the front drive shaft to get that out of the way so you can get your hand up in there or even just drop the oil pan what you're gonna have to drain the oil anyway before you pull the motor out so this there's alternative ways of going about it so we're gonna take those four bolts out and then we'll go to our next step which will be accessing and getting to the bottom bolts locking the block to the transmission alright just quickly so we got the four bolts out this is what they're gonna look like is four all the way around thirteen millimeter head like I said they're not all that easy to get at but you can get at them so the next step is now we're gonna be unbolting back in the block from the transmission will do the lowers first and then we've also got a disconnect the transmission coil whines because they are held by brackets that bolt up to the oil pan we'll get that out of the way and at that point well actually be pretty close to ready to take this out the last step will be taking the nuts running the nuts out of the bottom of the motor mounts and then we'll set this down and we'll start disconnecting from up top so we'll start with the transmission cooler lines because the brackets that lock them in place there's one area where the coil lines are right in front of two of the bolts that we need to take out for the transmission to block so you have a clamp here and then another one up front that's got ten millimeter nuts we're going to take those out and then that will allow these to float around nice and loose and get them out of the way we're gonna leave them in place we're not going to disconnect them from the cooler we're not going to disconnect them from the transmission this way you don't lose any fluid you won't have to worry about doing that after you do your reassembly all right so now we've removed and disconnected the three clamps on the transmission Coll line so they're a little more flexible now it gets a movement so this way we can move these out of the way push them out the way when we get to there are two bolts facing the front of the engine on the back of the oil pan and two on this side we need to take those out and then you have two on the bottom and then one on this side and one on this side and the rest we'll be able to do from the top will show you a little trick on how to get to that so from now we're gonna take those bolts out and then we're also going to remove the nuts that face down on the motor mounts once we've done that we're pretty much free and clear underneath and then we can get back up on top and get the rest of the bolts out and get this engine out all right so now before we throw these bolts in the trace we're gonna do is I want you to show you take note you got different length bolts that come out of each location you got these four bolts or what's going to come out of the back of the oil pan into the transmission these are the two that are up higher at about three o'clock and nine o'clock and then these two are the ones that run through the bottom of the pan into the actually the bottom of the transmission bell housing and into the pants so just take note of the links so that when you go to put it back together you put the right bolt and right hole so we're going to throw those in one of our trays and we'll put that aside and now we'll get to the two nuts for the motor mounts alright so now that we've got the transfer the transmission to block bolts out on the bottom we're gonna take the two nuts out of the motor mounts you have an 18 millimeter nut one here facing straight down and another on the other side pointing straight down so you can get at these with a long extension and a good size ratchet a breaker bar or an impact gun once as it goes out we actually have a little hidden bolt right up here which holds this knock sensor harness up against the block instead of being a plastic clip it's actually bolted on so we're gonna get a half-inch socket on that and zip that out and that should pretty much clear us from underneath after this pretty much clear sailing we do need to drain the oil and remove the oil filter before we put it up before we put it down on the ground so that's pretty much that's pretty much it from underneath so let's get that done and we can set this vehicle down on the ground so now we've got this set down and we're ready to finish off the top end disconnect so that we can pull this motor out so what we're going to do at this point is we have the lower the upper : hose right here that runs from the thermostat over to the water pump and then over to the heater hose we're gonna remove that so we can move that out of the way you have an electrical connector right here for the oil pressure sensor and then there's another underneath for the camshaft sensor there's a plastic connector in there with a squeeze tab on it and you squeeze that down we'll disconnect that by doing that this harness here will be fully disconnected and we can swing that up and out of the way and get that out at that point we should be able to easier easily get at the oil engine oil cooler which some vehicles are equipped with some are not and you'll be able to tell this is one of the lines right here for the engine oil cooler then there's another that comes in up below a 7/8 open end wrench will crack that loose and we'll take those out we've already drained the oil and we've removed the filter so when we take that line off we're gonna drip a little bit of oil but not too bad so maybe you want to put a rag or some speedy dry or something underneath just to catch that a little bit so let's get this apart so we can get the engine hooked up and get it out of here alright so before I pull the hose off on just a few things the clamps that are gonna hold that hose on are nothing more than just a squeeze type so you're going to grab your trusty pair of water pump pliers squeeze down and on and lift them up now what will happen is these are probably been attached for quite some time they're not going to come off easy initially and just take the water pumps set it up for about the right size of the hose and if you grab around the end of the hose and twist back and forth all of a sudden they're just going to crack loose and then you grab just to the outside of the pipe so as you squeeze it rolls the hose off now before I pull this off there's going to be some residual coal in there and probably sitting in the pump so I'll throw a pant or catch pan or something underneath so that's gonna catch that so now we'll just roll that out so we'll do this and this the same way this holes will be out of the way alright so here's your two connectors removed this is the one for the oil pressure switch there's a little metal spring top you're gonna depress that and then this will pull right off this one is a little more difficult because it's in an area you really can't see but this is the tab I was talking about it runs across the back you just reach in underneath with your fingers and just give that a really good squeeze sometimes it helps to push it into the connector squeeze it and you'll actually in most cases you might even feel or hear a little click and then you'll pull that right out so now we need that harness up out of the way and that opens up your view now to the two lines for the oil cooler you have one right here and there will be a 7/8 open end wrench it'll crack that loose and then the other one underneath again it's just it's a no see but you can feel it you feel the pipe run up and there's a nut the same size as this one right up underneath we're going to be able to sneak a wrench in and probably have to tap it with a hammer just to get enough leverage to be able to swing that wrench and this is the transmission coil line you can just push this down out of the way it's flexible now because we've unbolted it from underneath and once we get those two out then what we're gonna do is we're get-- the engine crane hooked up and the trick to getting the back bolts and we're at least getting better access to them has been that with the lift we're gonna pick the engine up we're gonna unbolt these brackets on both sides take the motor mounts out completely lower the engine back down and it will now lower three to four inches lower than it would be with the mounts which exposes the pop bumps in the back and makes it a lot easier to get at them once we've got those bolts out this is ready to come out alright so we've got we're at the point we're ready to start pulling the motor we want four bolts up top that we've got to take out plus the motor mounts but before we do what we want to do is put some support under here under the bell housing of the transmission as you can see there's no mount and so when we pull this engine this is going to want to drop and it's going to want to drop down this is a woman housing so we don't want to bang it on a crossmember we don't want to bang it against the driveshaft we'd kind of like to hold it about where it is so that when we go to put the new engine in that we were able to line up the bolt holes a little easier so what I'm going to do is you simply use a regular pull strap these little straps are very strong and what I can do is I'm going to sneak it over the frame over the catalytic converters - under the bell housing back up to the other side and then come down to the frame and we have these convenient pull hooks that are on the discovery tools that they use done when they ship them over from Europe that they could lock them down in place in the container so these come in very handy right now so that's all we're gonna do right now is we're gonna run this up route it up and over under the bell housing back over the frame and we've got enough room between the frame in the in the body speak this through all right so in this case because of this strap the the turnbuckle or lock buckle right here was going to go up over the frame so you can also hook on the radius arm did the same thing basically over the frame under the bell housing back over the frame and hooked up there get a little bit more slack than I'd like so we can just take a little wooden block and throw that in there that's not going to go anywhere and so now we're basically ready underneath we've drop this back down and we're going to raise the motor enough to take the motor mounts out then lower the engine which will actually be now lower than it would be sitting on the motor mounts so you get better access to the four bolts on the top once those are out this engine is out alright and last but not least before we get into doing this though we realize we gotta take the hood off because we're going to need clearance we're gonna have to come up quite high you really don't want to put this hood will fall back but it'll only go so far before it starts digging into the plastic cow and possibly bending the back corners of the hood so relatively easy to take off one thing you definitely don't want to forget is to disconnect the washer hose pull off this nipple right here and then we have 4 13 millimeter head bolts we'll take those out and it actually will stay in place even with the bolts out while it's on the prop rod and then it's just a matter we'll take the prop rod we'll slide it down a little bit before you do call your neighbor a friend because this is definitely a much easier job for two people once you've got this out of the way and we'll get to work taking those top bolts out of the engine so you see now we have the hood off and what's very easy to take off like we shown and it's very light it's an aluminum hood now we have that out of the way now this opens up the entire area to make this much easier you'll also notice what I have hooked up to the top is what they call a load level or for a portable you can rent them you can buy them they're not that expensive and they just make the job so much easier essentially what happens is you'll be hooking this to the engine hoist and you can turn this handle so change the position of this Center bracket and then that will actually change the tilt of the engine so that as we come up and out it'll make it much easier and it also makes the installation 10 times easier so something you want to consider before you go pulling it out so what we're going to do now then is we're going to unbolt the motor mounts where they bolt to the engine block we've already got the two bottom pins done so we're gonna hook this up pull this up a couple inches access these inside bolts is to there's actually three bolts that hold them out to the block once that's out of the way we lower it back down we're gonna be only get to those back bolts all right so now as you can see with the motor mounts and the brackets removed in the engine load we've got very good access to these four top bolts on the top of the bell housing now we're gonna at this point all we need to do to move out of the way is the O2 sensor connectors for upstream you'll see one here and there's one on the other side they just slide over a metal tab that has an indent in it and you'll see a little push button right there on the top of the connector and you're gonna slide that to push that in towards the center of the connector to release it that connector will come out and then you're going to basically grab the back side of it with a push tab to separate the two halves of the connector to get that out of the way and then right here we have our crankshaft sensor connector and we're going to squeeze this top tab pull that apart that gets the wiring out of the way so now we have good access because the one bolt on this side and the other side at the lowest points are holding the bracket that holds those O2 sensors in place so the right in the way those connectors so we're going to remove those and then we're gonna take those four bolts out you can use if you have a flex head ratchet and a socket will work good they're gonna be half-inch heads I might prefer using I use a box socket wrench which basically has a flexible socket on one end and an open end on the other and that seems to work pretty well or even an offset wrench they're gonna be a little tight initially but once you break them loose they usually spin out fairly easy so we're gonna go ahead pull these apart take those four bolts out and then we'll be ready to pull this motor out all right so I'm going to show you a neat little trick being that the bolts on this are half-inch so we have a half-inch wrench we got a box socket down on that lower bolt I really don't have a lot of leverage so if you take a 3/8 break a bar and put a 3/8 to 1/2 inch adapter on it of course that adapters gonna fit right on the wrench and now you've got leverage to break this bolt so we got the four bolts out of the back we showed you how to take them out and at this point danger was ready to come out literally all I we did was put a little tension on the chain grab the front train back and forth and the engine just come right off the transmission in most cases that's how I've had them come off once in a while you're going to get one that's going to be a little tight you can take a long straight blade screwdriver and get in between the transmission there's and the engine is a couple areas that race the areas that are just for that purpose sometimes they just need a little gentle persuasion but for the most part they actually come right off so now we've got this away from the transmission we've centered up you're gonna check underneath you've got a couple cooling lines or whatnot that may grab a hold of something under the bottom so you just want to come up a couple inches at a time check your lines check your hoses a little couple inches at a time and eventually we'll get it right up and out of there now we have the adjustable adjustable top piece so that we can change our angle as we come up and as we come down by putting that in angle like this you sort of shorten the length of the block the other thing on the exhaust so going back to that piece of cardboard that we put in front of the radiator is also going to protect it in case this suddenly swings forward this suddenly swings forward and touches the radiator and we're gonna punch a hole in it we can square this off it's a snug fit but it does come out try to hold it square we don't catch the wiring harness in the back and you come up now remember to as your arm comes up it shortens the distance so that this engine is actually going to move forward a little bit as you're coming up so take that into account you just want to hold it back just a little bit we're gonna have to go up quite a way because we still have the oil paint underneath there forward where the adjustable comes in real handy we can pick up the back end a little bit and clear the oil pan and there we go she's out now it's just a matter of getting things prepped on the new engine that's going to go in and we'll reverse the process alright so we have the engine sitting here and then what we have to do now is we have ancillary parts that got to come off this engine that are going to go on the new one because they don't come with the new short block and you're looking at flywheel Assembly your starter front cover front pulleys and then we still have the crankshaft position sensor and in some engine designs your replacements not going to come with an oil pan either so we're going to remove the oil pan and that basically is stripped a block down to its bare essentials you know you would be getting new lifters and some other pieces on there but for the most part we're gonna need the majority of their loose outside parts on this to transfer over so first we're gonna start with the flywheel are actually flex plate and then a torque wheel because this is for automatic transmission this is the flex plate that bolts to the torque converter there's your gear sets right there for your starter starter on the other side and the course front cover an oil pan so let's start at the back and we'll work our way forward alright so starter first you have two bolts on the starter one top one bottom eight millimeter hex drive and I'll run that there and we'll get those two bolts out I'm sure we save our hardware we're gonna need those bolts to put it back in and now we're going to take flexplate and torque wheel off now something you want to do when you take this flex plate off these are notorious for a hairline cracking where the bolts go so you want to give it a really good inspection to make sure no cracks no stress fractures nothing on that so we this one looks clean put that aside then we have our large spacer and then the flex plate is basically held on by a hub and we've got six bolts right here that have eight millimeter hex drive in them and we're gonna take those off now these are in these are in really tight plus when they go install from the factory they're also held in by lock tight so I find sometimes even an impact done isn't good enough to break them loose now you can either put like I said a large screwdriver through here to kind of hold it in place I have a tool that's been around for a long time and is used specifically for holding a flywheel or attorney so we're gonna use that to hold it and I'm going to put a breaker bar on this with a reducer adapter so that essentially we're going to reduce down from half inch drive to 3/8 drive meter then we're gonna break these loose by hand and take them out okay we have that off make sure again save the hardware put it in a spot where you're not going to lose it so we're gonna do now is the last item in the back is going to be crankshaft position sensor which is on the left-hand side of the engine alright so the next thing we're going to take off is the crank position sensor and we've got basically an insulating cover over the top of it so we've got two bolts here that are seven millimeter we're gonna take those out take the shield off and then under that is two nuts on too long studs and those are eight millimeter and once we take those off the sensors out alright so we got the two nuts out we've got the shield off and then you have the spaces here that lock it in place again put them in a safe place don't want to lose them and then you just slide that crank sensor right off those studs don't worry about the rest of this this will come on the new short block so now at the front of the engine we've got water pump pulley lower pulley and front cover so we're gonna do is zip off these three bolts take that pulley off 15:16 so take the main crank pulley off and then from there the damper just slides right off to things you want to look at when you get to that point you want to look for heavy cracking and splitting essentially a vibration damper or this lower pulley is a center hub with a rubber ring and then the outside pulley I've seen a number of these come apart this rubber dries out and the whole outer outer area the pulley area can actually slide right off and cause damage so if you see any dry cracking and whatnot I would suggest replacing this and then on the water pump I would suggest if you're going to put a new engine in you're gonna take the water pump out replace the water pump put a new one in you really don't want to take any chances on overheating or have the thing go a couple months down the road after putting a new motor so just a suggestion so we're going to zip this off and get this out of the way so we can take the front cover off all right so at this point now we're at the water pump and what you have is four bolts here here here in here are 7/16 or 11 millimeter and these go all the way through into the block and then the shorter ones the 10 millimeter are the perimeter bolts and once we zip those out we can take the water pump right off and then from that point we're just going to take all the perimeter bolts off of the front cover and the front cover will come out as well so here's the water-pump like you said once we took the bolts out of tap straight off definitely want to replace the at least do the gasket on this now right underneath it is your camp position sensor we're gonna zip this off there's an 8 10 millimeter bolt and that's going to come right out and then we're gonna do our perimeter bolts on the front cover all right so two things to note you'll notice that when you're taking the perimeter bolts out the bolt that's in this position has a little bracket on it you want to make sure you make note of that so when you go to reassemble the bracket ends up in the same place that's the basically the hole down for the connector for the camp position sensor we want to make sure about that now you've got the perimeter bolts in there are also three nuts underneath there are studs that come down through the front cover and go through the coil pan and you need to take those three nuts out as well now the studs that are fairly long so you can do this one at two ways you can either take a little stud puller and pull those three studs out in which case then you can just take the front cover and pull it right off or what we need to do now is we need to unbolt the oil pan so that we can get the oil pan down out of the way so that we can then pull the front cover so we're gonna take care of that oil pan right now now what I'm gonna do is this is kind of a neat little trick you got a little bit of a stub that sticks out of the back from the crankshaft so you really can't lay this right up on end without some kind of a spacer so what I do is use that point there and we got some coolant left in there so now that we've got this leaned up you can see you've got a row of bolts on both sides basically we've already got the back bolts out and when we pull the engine you got a bracket right here that we want to make sure we note when we take that off and then there you can see where your stud is this one came out with the nut but again there's your there's your three studs so we're gonna zip these two premier lines of bolts out that's going to move the oil pan they'll be the oil pickup tube we zip that out and then from there we can just take the front cover off all right so we've taken this line of bolts out now just the note you have two more down in these wells these are at the very back of the oil pan and up inside so a lot of people forget about those I've zipped those out so now we should have all the bolts out so we can tap off the prefer to use a rubber mallet as opposed to a steel hammer obviously because it's aluminum you don't want to you really don't want to crack it you just can see somebody RTV the heck out of this but you really shouldn't do something I'll suggest to afterwards once you get all this off before you go to assemble it may get some engine degreasers or cleanup or take these to your local machine shop and have them hot tank this what it'll do is it'll clean off all the oil and grease get all the money out of it you really don't want to put a new short block in and have something like this in the bottom of it so here we have the oil pickup - we got a 13 millimeter nut here we've got two eight millimeter bolts here that will take the oil pickup tube out and then from there we can then remove the stock in there and we can remove the front cover so something also make know enough here's the yeah here's your I'll pick up two removes you have an o-ring here at the end and definitely want to replace that before you put a new one back in always put a new o-ring and then take a note that you had a stud a nut and then this spacer that went on the back of that bracket then the bolt would run through and then bolt to the block and that put this in the proper position so now you've got basically you've got everything unbolted and then we can just take a rubber mallet on this Center should break it right loose again whoever somebody's been into this engine before and obviously really likes our TV which is sort of a no-no plus they've got washers now between the oil pan and the block which is also no no and we'll lift the front cover right up and out now I'm gonna make a note we've actually touch base on another video about these front covers but essentially what you have here you can take these six Phillips screws out or actually I think they're posi drives now these are Phillips and inspect your oil pump alright you have an inner gear and an outer gear the outer gear basically is the rides against or sits in this housing the front cover so you want to make sure there's no scratches deep marks or whatnot they can affect oil pressure any marks at oil at all any scratching you want to replace the front cover and these oil pump bolts so just a note so that's pretty much it you've picked off what you need to strip off the rest is going to be on the new short block you put in and again would be a really good idea as far as the auto-pay in the front cover if you can get them cleaned off as well as possible would also be a good idea to do two valve covers at the same time and just get those items cleaned up so not only will you eliminate the fact that you could have somedirt or contamination so inside of them when you put them on the new short block but also they've making a cleaner approach to make it much nicer when you sort and put it back together and the engine itself will have a nicer appearance so we're ready to start putting this together we're gonna start at the back and essentially show you is that how to reinstall the the flywheel the flex plate and the starter that basically is going to kompis the back and then of course your crankshaft position sensor so we'll start with the flywheel and if you notice you have a pin to stick the back of the crank and that pin is gonna go to your locating hole and you'll see this sort of toothbrush all the way around that's an indication that's got to go towards the block because that's where the pin from your crankshaft position sensor is gonna ride so I usually just take one bolt and we get that locating pin lined up we can rack this back and forth until it drops in just take one of the bolts and we're gonna start we're gonna leave that half hanging out reason being is now we're going to put the other five in we're gonna put a little drop a thread lock on it and then we'll take that one back out put the drop a thread lock in and put that in all right so we've got a little thread lock you can pick this up in any automotive center and we're just gonna basically put just a little stripe right there it doesn't take much just need a little bit go in and we're gonna do that the remainder three bolts so we're gonna take this one back out actually even at this point we can do so now you got two bolts in there to keep the flywheel and dropping out squeeze a little bit on there and then put that back in alright so we're gonna do the other three the same way and then we've gone to the book and refer to your torque specs and these six bolts get torqued down to 58 foot-pounds handy little tool sort of old-school not many guys have got them anymore but this is basically for holding if it's a flywheel holding tool and they are still available so we're just gonna go around we're going to torque them all up to 58 and then we're gonna go back around and just recheck them all so you'll notice on the first torque I do it and diagonally I go across sort of in a star pattern and then just to make sure that you've got them all what you do is start at one point and then just recheck them all the way around in a circular motion so you know you've got all six and all all more torque to the right spec alright so the next thing we're gonna put on is the flex plate now you can see these are relatively thin you see these markings on here so you can see that this this originally was bolted to this side would have been to the transmission and the one with the full circular pattern would fit what you've got here so they would go on in this direction it really doesn't matter if it's the same both ways this is the plate that connects the engine to the transmission the full load of the engine basically goes through this plate to get to the transmission so what happens is on these and I've seen it happen many times they get a hairline cracking them something usually right in this area from the bull hole out to the outside and they give you a noise when they operate so you want to make sure that you inspect it really good put a good light on it go over it make sure you see no cracks in there whatsoever before you put this on so we're going to set this in place put a dab of Loctite on there just to make sure and then these get torqued to 33 foot-pounds alright so next what we're going to do is we're going to put the crank position sensor in that's going to run right here now this is a Bosch engine on the GEMs it'll be a little different but the positioning is the same and what we have then is essentially the sensor goes on then there's a pair of spacer barrels the nuts and that locks the sensor in place and then there is a heat shield cover that goes over the top of that with two long bolts the nuts that hold the sensor in are 8 millimeter the two bolts that hold the shield on are going to be seven millimeter so get your tools accordingly alright so just something I wanted to mention that should have mentioned earlier you had that groove cut in the back of the flywheel as I mentioned the the crank sensor rides inside that groove there's a little pin off the front of the crank sensor I've seen in many cases where when the process of taking the old engine out and that we're reusing the old crank sensor that sometimes that pin can get bent in the process so you want to make sure that you look at that pin it's nice and straight and you can actually look down in the opening here between the back of the flywheel and the block and you can see the pin of the crank sensor sticking out and it should ride right in the middle of that groove if that's the way it's set up then you're perfect you're fine but you just want to double-check that all right so put on the back is your starter and this is definitely a lot easier to do it now than after you drop the engine in place because this top bolt can be a bear so they're essentially the same style bolt is what you had on the flywheel 8 millimeter there allen head one on top one on the bottom we're gonna slide the starter in start the two bolts torquing down to 32 foot pounds and we'll be in and that will basically be it what we need to do with the back then we're going to show you how to put the front cover on in that area alright so just a quick review crank sensor crank sensor cover flex plate flywheel starter so now we get everything on in the back and then what we're gonna do next is front cover alright so now we're into the front of the engine and the first thing we're gonna do is put the front cover on the front cover includes your oil pump and it's actually a fairly large component and the reason we're replacing it on this because we've checked it out and we've looked at the old oil pump there's a little bit of scoring and there's some where you certainly don't want to put an old oil pump that may not be able to bring oil pressure up to where it's supposed to be on a brand new engine you want everything nice and tight so we're going to put a new front cover on it so the first thing I like to do we're going to do two things to get this prepped we're gonna take some sealant that I call it what it's called high-tech and we're gonna spray some sealant on this surface right here where that front cover makes contact and even before I do that going to pour some motor oil I like to get the chain nice and wet before I put that in this way and when I get to the point where I'm ready to start the engine I know I've got a well lubricated chain so I'll just grab any one it doesn't matter because it's mostly gonna drip off so the replacement gasket you'll notice has a black bead on one side and not on the other and this is actually going to sit in this position and you notice when I sprayed I also sprayed around the coolant portals on both sides because we want to get a good seal there and then what we'll do to now is we'll spray the back of the gasket and we're going to wait about five minutes late get a little tacky this is gonna do two things one it's gonna help seal better two it's gonna hold the gasket in place when put the front cover on we don't have to worry about pinching the gasket or having it seen out of place when we go to install it all right so gaskets in place you can see this does a really nice job holding it's got nice and tacky and we'll just a little fingertip tap there now if you don't like the the red that shows up around the seal or don't worry about that after you put the cover on you can shoot a little brake cleaner on every why not washes it right off so you won't even see it so everything's sitting in place now when you put the front cover on as they mentioned earlier the oil pump is part of the front cover if you wanted to get more information on this we actually have another video that basically is a overlook of how this is put together so here's your oil pump drive and you have a key weight on the crankshaft what we're gonna do is we want to kind of get an idea what angle that pin is that we kind of want to set this inner gear and about the same angle and it'll just make the installation easier you know we need to do really is to just line that up and slide it on so once you push it in place you'll notice now you have two locating dowsers pins here and here once you get this up in place you're gonna line those up and this will just set right in place so now it's nice and square so we're gonna do at this point is we're gonna replace install the lower bolts and we're just gonna set them in snug I'll you'll notice that some of these pass through into the block so it's recommended by Landro we're gonna put a little black RTV on the threads just so that it seals all the holes because there's a couple in particularly that paths actually go through into a water jacket in the block we certainly don't want that leaking so we'll take the bolts we'll put a little sealer on there we'll set them in place and then we're going to torque them in so we put a dam up black sealer black art any of each one of these right you got the one long bolt here and then the others are all the same length and then just take note you have a bracket right here on this particular bolt this is the bracket that's going to support the connector for the cam position sensor which is going to go right here so all you want to make sure you put that on so factory specs your recommends torque specs of 16 foot-pounds you start in the middle and then we work our way around in a circular pattern all right so we're all torqued up on the bottom bolts because we're gonna have actually two more right here and another here and then these also pass through into the block and then we've got the water-pump bolts we're gonna do that in a few minutes but on the original front cover there's an adapter right here that does a 45 degree for the oil filter and we're gonna have to take that off the other cover to install it here now it's nothing's it's sealed with an o-ring so I just wanted to explain that and we're gonna show you this is three bolts you take that off and then we're just going to transfer it onto here so this is the elbow that we're talking about and you got four bolts that hold it and I pull the bolts out they're usually on there pretty stiff so you have a little bit of a land that sticks out right here and over here so you can tap on that with a hammer because you will have to knock it off so we've shown you the piece that's got to come off now in the old cover you're also gonna find this adapter and this is what that elbow would seal on and it does nothing but just thread over the existing threaded shaft you're gonna just run that up in there and it's because it's a one inch socket we'll put a deep socket on it we got to Snug that in and now what will happen is when we put the elbow up it's going to seal around that o-ring so put a little Vaseline on there just to make the ease of the installation we'll tighten it up and then we'll put the elbow on all right so water pump is gonna go on next and same thing we did with the front we're gonna basically look at the let's look at the configuration and looks like gasket goes on like so so we're going to spray the greenside we're gonna spray a little bit on that will they get tacky for about five minutes and then we'll be able to put the water pump on all right so actually the book gives you a torque spec where it's the same as what we did on the front cover below it's going to be 16 foot pounds and you have the three bolts this one here here and here which have a six 7/16 or 11 millimeter head on them and you're gonna torque those to 16 foot-pounds the rest of them they're ten millimeter heads and they just go directly into the top and you can see they're open holes they don't go into any water jackets and those are just gonna grab a ratchet and Saki and you're just going to Snug them in all right so last two I am is last but not least we don't want to forget we definitely got to put the cam sensor back in and that essentially is going to now you before you put it in make sure there's an o-ring that sits at the bottom you want to make sure that's there so that that goes there and then of course there's our bracket now what happens on a lot of these the two little arms that act as guides to slide over this you'll see in this case coming apart they broke a little arm breaks so you can tuck one sight in and we're just gonna wrap a little wire tie around there and lock that in place so I'll just to show you what the finished product is we got a wire tie locking this in your wire your hole that's in the camp sensor for the bolt the bolts got through it the clamp in place so everything's all locked down nice and tight now we're just going to put the front pulley on and lock that down and we'll be all done basically with the front alright so same as with our pump did you have that key weight and it extends out through the oil pump so that it also locks onto the front pulley you can see the front pulley has a cutaway for the key so we get them pretty close to about the same position we'll wiggle the Sun and then we'll just wiggle this till we feel it drop in put our bolt on now if you have access to an air compressor and a half-inch hammer air hammer I would suggest use that this bolt calls for a torque spec of two hundred foot-pounds which is real hard to try to hold by hand if you can get somebody to run a tool around the flywheel to hold it in the back while you apply pressure on here or run it in with an impact because that may get you close to the 200 I've had great success over the years I just run them in with a half inch impact that usually tightens up to a little over 150 foot pounds and they never come off so now at this point we're ready to drop this in place so we're going to set this up so that we can lower it in place get it bolted up to the transmission and then just as we did when we took it out where we're going to attach it to the transmission and set it down lower than it normally would sit to gain access to these top four or five bolts and then once those are in we're pretty much bolted up up top we can lift it put the mouth side settle it down the engine action at that point will be in place and ready for assembly so at this stage of the game where we where we're at is they got the vehicle set up on the Left we've raised the lift up up a bit so that we have room for the legs for the for the crane with the air out of the front tires got to get the nose down so we can work our way over without having to climb into it so basically what we're going to do at this point is just simply Jack it up set it over the top and drop it down you notice the oil pans not on the reason for that is your sump is about five and a half to six inches deep which is that much higher you're going to have to Jack the engine to get up and over the radiator support so leave the pan off you can bolt it in once this is in the vehicle and on the mounts it's still very easy to install a pan from underneath so what we've also done is at this point I have a jack stand set up underneath the transmission with a wooden block on it to protect the pan and we can raise and lower the lift a little bit to sort of raise and lower the transmission position so that we can easily get into those top bolts and bolt up the top on on the motor now the other thing I was going to suggest or that I always suggest is you want to set one of the bolt holes for the trim for the torque converter that on the flywheel at about a seven o'clock position and then do the same thing for the torque converter so this way the two bolts are relatively close to each other so once you get the engine in and locked in it doesn't take much just to move one or the other to get it lined up so you can put that first bolt in and then after that it's just spin it and bolt it up and we'll cover that as we go along so that's where we're at right now so if you're doing this on your garage on jack stands then you can always do the height change on the transmission with a floor jack now as of right now you know we've got the strap underneath and that's basically just to keep the transmission from falling out from underneath so so we'll put a wooden block on the and of the floor jack just to protect the pan of the transmission and slide it underneath and you can raise and lower it that way so here we go let's put this engine in so you'll see something that you may notice the strap that I have on here essentially what has happened is a lot of these wealth the lot of these cranes the bar will not come out far enough to actually get the motor to reach against the transmission so using this tool and raising the lower in the vehicle on the jack I can get the angle or the transmission and the engine lined up and then once we got the engine down in its proper height we basically put a ratchet strap on here on on this pipe that's basically as I pull the ratchet strap it's pulling the pipe forward pushing the engine back up into the transmission so we're able to get the right angle so right now we're in we're all lined up so we're gonna get the top four bolts in and then torque those up and then we can lower this down and start getting things ready to put the mouse on it and get that in place all right so you see the engine in this position we've got the four bolts in on the back we've talked them in now like I said you're not going to get a torque wrench you need just gonna have to set them in really tight because obviously they torque them up before they put the engine and transmission assembly and when they first built the vehicle so now what we're going to do now is we're going to pick this all the way up so that we have enough room to attach the mounts on each side we're going to show you that and then from there we just set it down and that's going to essentially put the motor in place and then from here we can lower the vehicle on the lift and actually start assembling the top end and bottom end of the engine alright pick this all the way up we want to watch to where the bellhousing of the transmission just barely touches the bulkhead and then what happens is when this raises this shorten is essentially the arm off the front of the vehicle so the other beauty behind this tool is we can crank this in and as we do that it's also going to move the crane back a little bit from the vehicle so it's not up against the front fender all right so we're all the way up in the air now I'll show you what we have to do with the mounts so what we've got in a used driver's side and you'll see this is a new mount of course you know when you first took the engine out you're gonna inspect the mouse if you see a major cracking or even a separation of the mount from the plate then you know you got to replace it so we've put a new mount in but usually the original bracket it's nothing more than an 18 millimeter nut with a stud just change that pick the nut off that'll remove the original amount put the new one in lock it down and then tighten it good and tight so essentially the mounts it's like so down underneath now it's kind of awkward because you have one bolt on top and two on the bottom and of course one of the lower bolts is sort of hidden behind the bracket all right so we're gonna lower the mount down in there and just line up the top bolt and we'll run that bolt in not tight but we're just gonna run it in till you feel snug and then back it off just a few turns so that we have a little slack so we can line up and install the two lower bolts you know we only need to get the lower bolts in by four or five threads the rest we'll do from underneath and then we can when you come back up top to assemble the upper area then we'll tighten the upper it's all in sequence so we got that in place so just to show you what it looks like in place this is the driver's side mount and we're essentially just gonna do the same on the other side put the top bolt in put the two bottom bolts in as far as we can by hand and then we'll set the engine down because obviously it can't go anywhere once it's done that and we can tighten up the ball and bottom bolts properly from underneath all right so just a note don't be afraid if the stud under of the mount doesn't Blayne right up with the one on the frame everything is built in tolerance and that's why they use rubber mounts you'll notice the stud here we've got slack on the chain so the motor is just sitting there the stud doesn't quite line up with the frame but that's why they make flexible mounts one tap and it's in will do the same on the other side we can disconnect the from this and then set this down all right so just so you get an idea say here's how your passenger-side mouth should look now on this one instead of being behind the hole as little to the outside just nothing more than just take a little screwdriver and give her a little push and it should drop right in so now the engines sitting nice and square on both mounts take the head bolts out and then we're gonna put the vehicle up in the air and we'll start assembling underneath all right so from underneath the vehicle now you can see you got a lot better access to the two lower bolts on the mount same width on the other side so at this point with a 15 millimeter race we're going to tighten those down good and tight and then we have the 18 millimeter nut and we're gonna do the same thing we've got to basically block down the mounts you can get up into these with a long extension an 18 millimeter socket well tighten those down good and tight and that will lock the motor down all right so the other good reason for leaving the pan off when you put this in is to access the four bolts that lock the torque converter to the flex plate as you can see when we explained earlier we want to get them fairly close in position and of course they never line up but you can't blow the torque converter very easily you can slide a long screwdriver just under the flywheel and then just move that torque converter up so you can see the bolt holes so there we are we're all lined up and we can put the new bolts and put one in leave that a little loose so that we can get the other three and easily and then we'll go back around and torque them up now to spend this the easiest way I found we've got the front pulley on so you're going to take a fifteen sixteenths socket and a ratchet put it on the center front pulley bolt and then we can just turn the whole engine around to access the other two bolts all right just a note when you get this top you're gonna see this open porthole right here with the two threaded bolts the essentially Land Rover head reused the same casting from the old GEMS engines where the oil pickup would attach here and come down would feed up through a galley that's up in the block well when they went over to the Bosch system they changed the design where you pick up tube now attaches all the way up here in the front cover so don't worry about leaving that open because that galley becomes blocked off when you install the front cover so don't worry about that when in case you're wondering what that is or if anything needs to be attached there with the Bosch engines you do not worry about that just leave it the way it is all right generally the procedure for doing the torque converter bolts because we're going to put lock tight on this but we don't want to put it on the first ball because we're gonna leave that a little loose and we don't want the stuff setting up with the bolt in that position so essentially what you're gonna do is you're gonna put the first bolt in you're gonna let it snug in back it off about a turn or so so it's loose the next three when you put those in you're gonna put a little dab of Loctite on those like we showed earlier with the flexplate bolts and then run them in take this one back out put the dab on it run it in and then we're going to torque them up all the way around so our next step is going to be to add the four bolts at the middle of the bell housing what I've done is I've started the bolt just so you can see the location one here one up above and then you're going to have two on the opposite side pretty tight to get at and again they're a half-inch head what I've used to get at these has been like a very long 3/8 drive extension with a half-inch deep swivel on the end and then a regular 8 inch 3/8 drive ratchet and with that we can run those in and get them pretty good and tight it's gonna be really hard to actually torque them so all I can suggest is at that point once you snug them in just give it a good hard twist lock them in and you're done on the bolt above because the right midsection are in a very tight spot I found it the best way to get to those is a half-inch shallow socket with a three inch extension and 3/8 drive and then a universal to your long extension in your 3/8 drive ratchet yeah they're kind of tough to get at but you can do it so our next step now is we're going to put the oil pickup back in now you look on the end of it and you'll see that there's an o-ring on the end and then your gasket set will come with a replacement actually it says right on the packet hole rings strainer and pipe we'll just take a small screwdriver and usually these are still fairly flexible we'll just peel that right out of there put the new one on and I always keep a little tub of vaseline or even a little motor oil or work whatever you happen to have around we're going to lube it up just a little bit so that when we install the strainer it's not gonna twist up the o-ring.
