Kit #: NLP000030SKA Installing Spark Plugs On Range Rover Full Size (L322) 2003-2005, 8-Cylinder Gasoline, North American SpecificationHi I'm Doug, your tech support representative here at Atlantic British. And in this video we're going to touch base on spark plugs for your 2003 to 2005 Full Size Range Rover, also known as the L322. We have the plugs available as a kit through our maintenance and repair academy. Which is also down on this sheet which we'll show you is downloadable and printable from our website. And specifically for the 2003 to 2005 we have these plugs and they are matched for the vehicle. You have kit number NLP000030SKA. And what you get is 8 Champion replacement spark plugs which is the recommended plug for this vehicle. You'll see it has the tripod tip. It is a platinum. And you get the full set of 8. So, it's recommended every 60,000 miles. If you do a lot of towing, or you put your vehicle through hard service you might want to change them over a little bit earlier, say at about 50,000 miles. Spark plugs generally do make a huge difference as far as engine performance and your fuel economy. So it's something that you want to stay on top of as far as your maintenance. So what we're going to do is go through and show you some tips on how you can change over the plugs on your 2003 to 2005 Full Size Range Rover. Alright, so, what we're going to do is show you the basics on how to get to the spark plugs on your 2003 to 2005 L322. And we're going to start with just taking the engine cover off. I use a 5 millimeter, 5 millimeter allen with what I call a swivel ball end on it so that the 2 in the back you can get to at an angle and still remove them. And they're only just a 90 degree turn and they release. And we'll give it a little wiggle...Let go there. There we are. Alright, so, up and out. So, you can already see it gives you pretty good access to what you have underneath. Just nothing more than just a plastic shield. So now that we got the cover off and you can see we've got good visible here, there are, believe it or not 2 small panels that you can pop out that are going to give you access to 2 bolts that removes this upper cover. You can just barely see the outline. If you slide a small screw driver you'll feel it pop into place. Push that in that little slot and lift out. And there's another one in the back. And you do the same thing. You find the spot where it drops in. And pop it out. So there's your 2 small bolt covers right there for your valve cover. Now we'll take a 10 millimeter socket, and you can use quarter inch on these because these really aren't torqued in all that tight. Usually once you crack them loose you can pretty much spin them out with your fingers. There's 1. And we take them out, it's always good, put all of your hardware in the same generally area so when you go looking for it to put the vehicle back together you can find it. Just don't put it in a place where you're going to brush against it and knock it down into the engine compartment. Okay, so, there's your 2 bolts. And we lift our cover up and out and we'll just place it to the side. And there you are. You have access right there to all your coils. There's your 4 coils right here. And you've got essentially a lift bracket that disconnects the coil from the harness. And just get up underneath that. Lift that. That basically unlocks the connector and you can lift the connector up and off. So, the only thing you need to do then, to remove the coil, you have 2 nuts on each side of each coil. And again,..., all you generally need to do is crack them loose, and you can spin then off with your fingers. And again, just a little patience in taking things off so that you don't drop them down below and turn it into a half hour job trying to find a lost nut. Okay. And we're just going to grab the coil, and it's going to be a little tight, especially the first time. These boots sometimes have a tendency to lock on. Now's a good time to be looking for several things. One, you might be looking for a white line or tracking on the outside of the boot of the coil. Look for a lot of this, see this white build up. That little bit there is fine, but if you have an excessive amount or a high amount, that's telling you it's ozone. Something's burning in there. Which means you don't have a good connection. You may want to replace this boot. Now you can see the spark plug itself is quite a ways down in there. And we're just going to take a long extension. Now, something I'll suggest. I've had people ask me is it better to remove the plugs when the engine's hot or if the engine's cold. Anytime you're removing either spark plugs or a bolt from something, from an aluminum housing or case, I recommend doing it cold. When it's hot or warm, and all the threads are expanded, you have a chance of actually taking the threads right out of the aluminum when you're removing whatever it is you're taking out. In this case we're taking the spark plugs out. You definitely never want to change spark plugs when the engine is warm. Now we have approximately almost 100,00 miles on these spark plugs that are in this vehicle. You can see these are the original BMW. But they are an exact match for the Champions that we show you in the kit. Again, the 4 pin design. And you can see, actually relatively, this engine's running pretty well. So that's pretty much it. The process is the same all the way down the line. Each coil you're going to remove individually. Remove a plug. Change. Put a new spark plug in. Reassemble it just the opposite of the way you just saw me take it apart. The other side exactly the same. Nothing else to be taken apart. Easy access. So, when you're ready to change the spark plugs over on your BMW engine, 2003 to 2005 Full Size Range Rover, also known as the L322, give a call to any of our knowledgeable salesmen at 1-800-533-2210. And thanks for watching.
