Discovery Series II and All Rover Vehicles: When Rovers Overheat, What to look for & How to resolve.
Hi it's Jim at Atlantic British. I take care of the technical support here. This morning we're just going to do an overview of your engine is overheating. The first thing you need to do is check the obvious things. Check your coolant level. Like in this truck, you can see it right here. You can actually, you don't have to take anything apart. You can see the coolant is okay. Look at that. If it's okay, another thing is, you have an auxiliary fan up here. Make sure that's running when it gets warm. Also on most of the Rovers you have a viscous fan. When the engine's warmed up you can probably turn the car off when it's hot and just touch the fan. If it feels stiff, that means it's working. Next thing to do when you check for the coolant level, if it was down, you have to figure out where that went. Top it up and have somebody pressure test the system. Let it sit there and then look for obvious leaks. You'll see it on the ground. Discovery 2's are famous for leaking radiators. Everybody buys 2 or 3. Another common leak on this car, the Disco 2, or if you have a Range Rover with the Bosch engine. Over here, on the throttle body there's a heater down on the bottom. You can see 2 little hoses here. It's a throttle plate heater kit. We sell them all the time. It's a common leak. And some people can't figure it out. Some people go oh maybe it's a head gasket. But if you got a puddle of water on your valve cover there it's definitely that. It's a very common leak and it's not a hard repair. I believe we've gone over that at one time. After you do the pressure test and you're not seeing anything going on, like leaking out on the ground which would be hoses, head gaskets or that plate I was just talking about, you need to figure out what's going on. So pressure test it again, and let it sit for quite a while. While you're waiting, take all the spark plugs out. Have it set for a couple hours. And then with 2 people, have somebody turn the engine over with the spark plugs out and see if you're getting some anti freeze out the holes. That's going to tell you there is something wrong with the head gasket or possibly a block. If you tear this engine down, get the head gaskets out and don't see anything really wrong with the head gasket, I would suspect the block. You can get it pressure tested with the heads off. There's a kit that a lot of places have that can do that. If you have the liner problem, on these later engines, it used to be the liner would drop. The later engines that can't happen. They've change the blocks. But what happens is, anti freeze can work between the actual aluminum block and the steel cylinder. It actually works its way up and dumps into the cylinder. You can notice this if you start the engine up cold and it skips for a little while and then clears out. You're maybe looking at a block problem. Especially if it's one of the interior cylinders like 2 and 4 and 3 and 5. It's definitely a block problem. Here at Atlantic British we are rebuilding engines, we have a whole program going, and we actually change out the liner with what they call a top hat style liner. We bore the old one out. We push this new one in. It's sealed. It can't do that again. So if you do have the liner problem we can probably give you another engine. You can call our sales department at 1-800-533-2210. Explain to them what's going on. Think you may have a liner problem. And they can probably hook you up with a rebuilt short block. We also have all the head gaskets. All the hoses. Everything's in kits. It's easy to do. Just grab all your parts. Like I said, check us out on RoverParts.com. Or give us a call at 1-800-533-2210 and we can probably fix your overheating problem.
