Try to remove the thermostat and run it without it. If it does not overheat then you just have a defective one if you have replaced it. Or ou accidentally put it in backwards. It will not hurt anything.

96 Cavalier continues to overheat and blow cold air through the vents. I replaced the thermostat and waterpump and that didn't fix the problem.

If you don't have any noticeable coolant leaks, you might want to check the fan or fans if you have 2, start car and when it starts to overheat check to see if the fan is working. good Luck.

I have a 98 Cavalier, I have replaced the thermostat 4 times but it continues to overheat. It has a new water pump and new coolant. I replaced the head and gaskets after it overheated so much it warped the...

I have compiled a list of things for you to help you solve the problem of Overheating.#1 Radiator core blocked or radiator grill dirty or restricted.#2 Are the electric cooling fans turning on when they are supossed to? #3 Is the radiator cap maintaining proper pressure? #4 Check the ignition timing. #5 Replace the engine collant temperature sensor.The engine coolant temperature sensor sends Data to the on board computer thats how it determas part of the ignition timing and when to turn the cooling fans on and off.The only other thing I can think of is when you installed the new cylinder head did you use new cylinder head bolts? It is highly recomended to do so.I had a Cavallier myself once only a year or two older than yours and I put on a new cylinder head and every thing else.However in the end it turned out it was a bad Radiator.So I put in a new one and everything was OK. Good Luck and have agood XMASS.( PS/I hope you find this helpfull and give me a good rating).

My car is running hot within 1 mile of me driving fan kicks on when it wants to....i need to know how to fix it myself

replace coolant temp, sensor and check for a bad fan relay. check relay first ! to test the fans, run a wire from positive on battery to positive on fan connection. then run a wire from negative battery post to neg, connection on fan. if the motors are ok. the fans will turn on. and make sure you have 12 volts going to fan motors. check relay first!! the fans on a typical engine only work when idling or going slow to prevent it from heating up. have a good day!! make sure there is no coolant leaks anywhere!! this will cause it to overheat also. if need be replace coolant pressure cap on overflow, might not be holding pressure.

Over heating and radiator leaks. overheats after sitting at idle for around ten minutes. its a 5 speed manual transmission 2000 chevy 2 dr cavalier.

if there is a leak then of course you will get overheating from the engine..Be very careful as this can cause permanent damage to the head gasket and it will cost a lot more to fix..First try to stop this leak before you proceed further.
