This has been an ongoing problem, just last week I had new heads put on and gasket kit, new themostat, I have installed new sending unit and thermostat temp sensor, the engine will heat up all the way to the line just before Hot and then slowly climb back down, this happens with the A/C on or off. Currently with the A/C on it stays just above the second line from the Cold. I have replaced the heads on this car 3 times now. I have been told I may have a air bubble, I have cleaned out the cooling system using Preston coolant cleaner, ran if for about a week and then replaced all the coolant with new stuff. There is a hex screw in the thermostat housing unit I was told to loosen and this would allow the possible air bubble to escape? I cant remove it, it is stuck so I need solution to that, and the over heating problem, thanks.
have the same problem?
