Fuel Injector Replacement On Late Model Land Rover 5.0L V8 Vehicles
Watch Doug, our Land Rover Master Technician, explain removal and installation of 5.0L fuel injectors for all 5.0L V8 from 2010 to 2013 or 2014 depending on your model Land Rover or Range Rover. Doug uses a bare head in our demonstration to show removal and replacement of the fuel injector (
part # LR079542). Questions about this video? Call 1-800-533-2210. I'm Doug your tech support representative here at Atlantic British in this video we're gonna touch base on fuel injector replacement on the five liter v8 from 2010 to 102 thousand thirteen fourteen depending on what model and what we're gonna do is show you how to remove and replace the injector on a bare head because there are a lot of variations to the different model and Rovers out there that use this engine so what we're gonna do is just get you take it to the point where you've done the disassembly as far as the valve covers and the and the installation covers and again the differences between supercharged and non supercharged too many differences to list here so essentially just a matter of replacing the injector so what we have here basically is a high-pressure injector now if you're not familiar with the five liters they essentially use a low pressure pump normally it's gonna run about fifty five sixty pounds of pressure to a set of high-pressure pumps that are mounted underneath the engine and they in turn are gonna raise your fuel pressure to twenty one hundred foot-pounds of pressure which means at this point right here you have over two thousand psi of pressure so this is a system you want to be careful with now in the beginning Land Rover says of course the first thing you're going to do is you want to depressurize the system before you even start any disassembly whatsoever and that's relatively easy you go to your owner's manual you can identify the fuel pump fuse you're gonna remove that fuse and then just run the vehicle until it basically quits once it quits you're going to still leave the fuse out you're going to crank the engine another five or ten seconds just to make sure you've completely depressurize the system and then from that point you can take the lines off the fuel rail that's information you can look up and get online or talk to people on the forums you're even just invest in a service manual if you're gonna do your own work so at that point then you're going to take it down to this where we're ready to remove the fuel injector now two things I want to mention is there is a teflon seal mounted on the bottom of these that if you're going to reuse the old injector you're going to actually remove the the nylon seal and we're going to show you that in a minute and the other thing that land rover recommends again is these retainers that hold them in place once the fuel rail is in and from there they say you want to keep the same retainer with the injector if you were reusing the old injectors in this case we're actually going to be looking at replacement most cases you're going to replace them you're not going to reuse them so we remove the retainer and then we have the special tool and I do strongly recommend using this as its opposed to trying to get underneath and remove this as simply pushed in place but you really don't want to try to pry on it or you might end up doing damage below so you're going to use this puller which is essentially just a small slide hammer and these jaws at the bottom will spread and you're gonna seat the tool against the top which will get you lined up in that groove and then push this collar down to lock it in so the top essentially just acts as a small slight hammer now of course if you pullin up I use the injector and you've got varnish buildup on the bottom you're gonna need a little bit more force to take it off but it will come then you're gonna just simply raise that collar split the jaws and remove that now this is the nylon ring that I was talking about way in rover States if you're gonna just replace that ring you actually have an installation tool and a resizer the installation tool just seats over the end of the injector and you're gonna slide the new ring over that of course will spread the ring so once the ring is in place you have a sizing tool now this tool is labeled number one and number two so number one will slide over the end and bring the size of the of the o-ring down to a certain point well then you flip it around number two being just a little bit smaller and then that's going to run over the top of that and now your size the reinstallation again just that easy and really just the next step is to install the new injector and put your vehicle back together so now we're ready to install this injector now when you get a new fuel injector it's already gonna come with the teflon seal already on the end and it should already be sized we're gonna take the protective ends off and then now Land Rover recommends if you're reusing the old injectors if you're just taking them out to do with new seals and whatnot make sure that you use the retainer that was on that particular injector they should stay together there's basically stating that there may be up a mated or just the fact that it's sized to fit that injector you want to reuse the old one in the case of the new ones usually recommend get the new retainers they install very easily they essentially just slide over the top of the injector you can push that down spread them a little bit and so that's what your installed retainer is gonna look like now the other thing I like to do and I've been doing this with fuel injectors over the years and the fuel rails take some clean Vaseline nothing that you dirty that you've used for engine working one up just a very very light coating and you're gonna rub your fingers on the o-ring on the top and then just a little bit on the teflon seal on the bottom and that sort of gives you a little bit more protection from ripping that teflon seal when you install now in regard to installing the tool there is a ridge right there on the injector itself we're gonna take that retainer back off and just wanted to show you how they go on because we're actually going to really install it once it's installed in the head and then of course the removal tool will also act as an installation tool so we want to wrap that around that essentially so that the little tangs inside the tool are gonna grab around the top of the injector and then slide that down to lock it in place so then what you're going to do - you have to remember your orientation when you remove the injector from off the head as far as where your your connector is now in this case we have a brand new head I really don't have the orientation here in front of me but as far as the installation I'm just gonna seat that very gently and then just tap in place lift and separate double-check just to make sure no damage to the o-ring again we just got a nice light coating on there so then at this point then you can slide your new retainer on drop that in place and now you're ready to reassemble so that's essentially all that's necessary and we have been running into a lot of calls on these injectors I'm either due to electrical or just basically getting restricted on top from from varnish build-up and whatnot and because of all the differences on the 5 liters as far as super charging non super charged you just basically gonna follow your procedure the way you took it apart just reverse everything okay so that's essentially yet very easy to do when you have the right tools this being the most important because one you could try to pry that injector out of there with another tool you probably end up doing some damage that are very fragile and you got to remember dealing with the pressures that are being applied it at these that you want to make sure everything's together and clean and seated exactly right
