1999 Chevy Cavalier Z24 2.4L cooling fan inoperative

I have a 99 Chevy Cavalier z24, 2.4L. The car starts to overheat slowly meaning that the temperature gauge slowly increases past the mid-point. The fan doesn't want to stay on! It's strange, when the car first starts up(whether it's hot or cold), the fan starts and stays on for about 3 seconds and shuts off. As the car keeps running and warms up, I noticed the temperature gauge going past the mid-point and keeps increasing but the fan doesn't turn on. Could this be a bad ECT sensor?

Yes you could have a bad ECT or the relay could be bad it sounds more like the relay is heating up and kicking out

Probalby not, seeing that's what's telling your over heating. it wont be a bad idea to remove it (be carefull of hot fluid) and clean it off and put it back in. (wouldn't hurt anyways) but this problem is most likly a falty relay form the PCM to the fans. wireing might be corroed and need to be cleaned. check the fans for power and gorund with an omh meter.

1999 cavalier z24 lower 2 fan settings not working. i have already replaced the resistors.


It has to be the resistor but you may have a bigger problem. if the fan motor is pulling to much power it may burn out the new resistor as fast as you put them in.
I suggest since you have to take the fan out to get to the resitor purchase a used fan at the wreckers and replace both. That should solve your problem. You can be assured our new resistor is burned out again.

Engine over heated and will not start


Did you have oil in it. depending on the severity of the overheat you may have seized the engine. You also could have a head gasket problem. The cooling system on these little cars can overheat in heavy traffic and going up a hill a little too fast. Solution? If it started and showed white smoke out of the exhaust. Head Gasket. If it won't turn over with the starter it's seized. Both will cost a mint. If you had no oil engine could now be junk.
