hey i have a 1994 2.2 cavalier and it keeps overheating.. i changed the thermostat, and that didnt solve the problem, there is no coolant in the oil so i dont think its the head gasket.. the waterpump seems to be circulating the coolant, as the level in the radiator fluxuates with the throttle. all hoses have pressure when the car is running and the fan turns on..anyone have any ideas/?????
Maybe your radiator is plugged up or blocked in front.
Is the engine fan electric for this particular car? Is it turning on? If not, fuse, temperature switch/sensor or broken motor. Usually turning on the A/C will cause most electric fans to run continuously so you can check the motor that way. Is the car really overheating or is it just a guage/indicator problem? Did you put the thermostat in facing the correct way? The bridge usually goes AWAY from the engine. Some GM cars send coolant through the heater core all the time no matter what position the temperature lever is in. If the core is clogged the car will overheat. Radiator might be clogged, after 10 years I would say it's a good bet.
Is the outlet hose for the radiator cooler?
the thermostat is in right, i just replaced it.... the fan turns on everything has pressure.. water pump flows and radiator was flushed... anything else?? and yes its really overheating, not just saying so im clueless
Why do you think it is overheating? Have you used a real temp measuring device (IR or other)? WHEN does it over heat? Have you used a sniffer on the rad tank? Is the cap new? etc.?
