This video we're going to discuss and actually show you how to install a thermostat in a 4.4 LR3 or Sport, non Supercharged Sport, from 2006 to 2009. Now what happens is now is they're getting older, we're finding that some vehicles, and people talk about they don't get enough heat in the car, which is usually a sluggish thermostat. Or actually the vehicle will throw a fault code, like a P0128. It's saying it's not reaching its parameters or it's not reaching its full temperature. And that usually is also an indication the thermostat. What we also want to do is show you some options that you have, being more than likely the vehicle is going to be in like the 100,000 mile mark or more. So there are other things that you want to check while you have the system open to take care of, so you don't have to do it twice down the line. One of them obviously is going to be just the thermostat, which you can get. And you'll notice that this comes in 4 distinct pieces, that it's sort of like a build you own. And we're going to show you how to do that. It's part of the installation on it. And then plus your O ring for your outer housing. Now, the thing you might want to consider is if you're going to take the thermostat out, and some people prefer to go the whole route, this is the housing that the thermostat sits in. This runs across the front of the engine. You have 4 bolts here holding the upper section down. These 2 attach to the front of the intake manifold. And of course here is your actual housing for the thermostat. Now what happens is these have a tendency, as they get older, to crack, they split. It's a known issue. It shows up quite a bit on these. So you may want to take care of this, instead of just the thermostat. That will take care of 2 issues. Along with you also get a temperature sensor with it. Next step up would be if you have over 100,000 miles on the vehicle you want to take a good look at the hoses. Now this is the kit that you would us on the LR3. This way we'll run that clamp up without the upper hose being in the way. So this is the last of the 3. We put all 3 hoses on. We've got our clamps in place. Make sure the clamp is sitting where it was previous to disassembly. And you'll see the marks on the hoses. And then don't forget to pull over your little hoses that you stretched out of the way earlier. This way everything is where it's supposed to be. Clamps are on tight. So what we're going to do is we'll start it up. We'll let it run for a minute. And what that will do is bleed the air through. And then we'll let it sit. Top off the coolant level in the tank. And essentially you're done. We'll put the cover back on. And you're done. So, when you're ready to, or when you have to, replace the thermostat on your LR3 or your Sport with a 4.4, this would be 2006 to 2009, just call to any of our knowledgeable salesmen at 1-800-533-2210. And thanks for watching.
