2005 LR 3 Overheating/Leak
Hello everyone,
(2005 LR3 SE V8 106K miles)
A couple months ago i replaced my thermostat/housing because of a crack right by where the thermostat is. I could actually see and hear the leak. I didnt do the whole plastic assembly/housing, just the part right by the thermostat, the side thats not connected to the engine and doesnt require the throttle body to be removed. Problem fixed, no more overheating.
Today, i noticed a high-rev and looked down to see the temp pegged-out. Here we go again! When I pulled over and got out, it appeared that there was coolant on the inside of both wheel wells and on the tires. I also noticed coolant dripping from one of the bolts that holds the brush-guard (or whatever that big plate is under the engine). Pulled it off and there was plenty of coolant on it. I cant find the source though. It looks* like it may be coming from the front side of the engine, but I can't see where. Pulled the cover off the top of the engine and looked around the thermostat housing for leaks. I found what appears to be a hairline crack in the housing assembly;this time on the side that will require removing the throttle body. . The leak wasn't going crazy, just slow n steady, pooling up in a little groove right under the throttle body air intake. (I cleaned up the coolant that was there, but in the pic my finger is pointing at the groove where the hairline crack is) I didn't get on the gas or anything, just had it idling. I know that particular part has to be replaced, but I'm worried that it is not the only leak.
The top and side of the engine show no evidence of fluid on them. The bottom/front of the engine is the only place i can even remotely tell that there was a leak. Could it be leaking that bad when I'm on the gas/driving to shoot coolant out in both wheel wells? And at idle just sit there and pool up? I guess if most of the coolant was gone by the time I stood there and watched it, it wouldn't spray out all over the place. But, I thought I would have at least seen evidence of fluid on the inside of that plastic engine cover; but I dont see any wetness. Maybe it was so hot that it just evaporated? All hoses/clamps look good.
Any help is appreciated!
