Replacement Tips: Thermostat for Discovery Series II, 1999 - 2004Hi it's Jim at Atlantic British. I take care of the technical support here. The other day we had someone actually, I think it came of one of the YouTube videos, has a question about thermostats on the Disco II. It is a reasonable simple operation, but we're it is and what you kind of have to do to replace it. Here's a picture of the thermostat. It sits in the car this way. There are 2 hoses on the top, one on the bottom. Now if you are going to replace it, you have to get this top cover out of the way. There's 4 screws, 2 up here. There's another one straight down there. And another one over here, which I all ready took out. Just do a quarter turn on them, they should come loose. Get your upper radiator hose out of the way. Just lift it up out of there. With that out of the way you should be able to see where the thermostat is. I'm going to turn my little extra light on here so Cheryl can get it. It is right here. You can see the 2 top hoses and the bottom hose. Really all you're going to have to do with this is get a pair of pliers on this, take the top hose off. Pair of pliers just squeeze these and get that off. When you get that you can kind of turn it and do the same thing on the bottom. Disco II there is no real radiator drain. This is the only way you are going to get the coolant out of the system, so make sure you have a pan on the ground underneath there when you are taking the hose clamps off. Once you get your new thermostat in there, you put your cover back on, I don't really need to do that now, it is simple. The thing you need to remember, and I'm going to highlight it again, here is the bleeder for the cooling system. Before you do anything take this out and then slowly fill by the coolant tank over here, until you can see some water coming out of here. Then you are just going to start it up and let it run. Heat it up. Let the car cool down again. Check the level, top it up as necessary. Some people wonder what goes wrong with these. Common thing is they stick open and you don't have any temperature in the engine. Once in a while they'll stick close, that's not too often. Sometimes they get air bound. That will be if you have a leak somewhere in the system and a little air got in there. So if you fill it up and bleed the air out you should be fine. That's about it with the thermostat in this car. It is a very simple system. You can get thermostats here at Atlantic British at RoverParts.com or give us a call at 1-800-533-2210. We carry this 2 ways. This one in my hand is the genuine part straight from Rover, or we have an aftermarket alternative. You can buy that one. Same part just not in a Rover box. Check out your thermostats. You could have a problem there.
