not sure if you figured this out or not...
Hey all, first post. Wondering if you ever figured this out. I am having a similar problem on an 05 LR3 with 76K, started with a coolant boil over. I found that the bleed valve above the thermostat housing was cracked (replaced), thermostat was shot (replaced), bled system hoping to correct but no luck. Before the failed fix, the car would start up relatively normally (will have weak starts from time to time if a quick on and off), then after a few minutes at speed, the engine begins to heat up. At the same time, the heater isn't working. Ultimately I recreated a leak -I managed to find the source of the leak by force filling the system with coolant through the lower radiator hose and "pumping" - basically a low grade pressure test. I get a gushing flow from just under the throttle body, at the point where the engine empties coolant into various coolant hoses (it looks like it splits into two different branches, on to the throttle body the other to the rest of the system). I assume that this is the engine coolant outlet, like the DII coolant elbow that comes out of the engine. I've seen that item (the DII elbow outlet and gasket) discussed, but I can't find the part for the LR3. I'm guessing that when the T-stat failed, pressure built up in the system and did something to the gasket or the cracked part (I need to take the part out and replace, but I'd like to find out what it is). Any thoughts? I'll post pictures soon, and maybe a video so you can see this "gusher". It looks like I'm selling fractional oil interests in western Kentucky...
