I have a cadillac sts 2000. the motor warms up after a while and the temperature over heat. The prestone overflow of the reserve tank. I have made check the head gasket to a dealer and its ok. I also changed the cap of the prestone tank and it still overheat. Tha termostat has been changed and i vacuumed the prestone under pressure... what's wrong, the dealers and mecanics can't find the problem
