A BHG!!! Okay... My car doesn't overheat with the thermostat out. (obviously) But when I install the thermostat it starts to overheat. But only when I'm driving it. Its fine at idle. The radiator is full with 50/50. I can drive the car and it overheats. Well I figured out that if I get out and relieve the pressure in the radiator while the car is still running, it cools down. (quick) Dumb but it works. And thats it until next time I drive the car. The thermostat is new. There is no water in the oil and no oil in the water. ???????????? HELP
