I have a 2000 cavalier that had the top end of the motor rebuilt with all new gaskets. We had hit a deer and bent up the front end. Then rebuilt the whole car. Including the motor. But now it overheats constantly and the fan is working. It seems to suck radiator fluid down and bubbles out the radiator resivor. I have purged the system several times to eliminate air bubbles and changed the thermosat twice. It still overheats. Has a new head and gaskets so its not a gasket problem. But the funny thing is when the thermosat is out of the car it does not overheat. What could be the problem? Anyone know?
have the same problem?
