The coolant reservoir has a black cap with an orange label affixed to it.. Unscrew it many times to remove & fill about 3/4 ways up

Look if the engine is doing what you say then it is overheating and there is no problem with the sensor, remember the sensor only tells what is going on, it does not cause anything like overheating. Have you bled the system of air, there is a factory procedure to do this.

Check coolant temp


I just purchased a 98 Cadillac Deville which had sat at the dealers for a few months, when I drove it the check coolant light came on, I checked with the dealer and he added coolant and it went off,I'm going to keep an eye on it but as the devilles seem to have head gasket problems and that might be the first sign of a bigger issue. Hope this helps and remember to add ONLY Dexcool antifreeze as it is what is required and most auto parts stores carry this

1998 cadillac deville , cooling fans for rad will not come on and I already replaced the AC comp relay


The only other things would be the coolant temp sensor or the engine computer. Alot of the new GM's have the on and off function of the cooling fans controlled by the computer. If the coolant temp sensor is ok, then most likely the problem is in the engine computer.

Overheating problems


well check your coolant level first, if its low add some coolant. if that does not help i would assume your thermostat has went out and needs to be replaced

1998 cadillac deville looses about 1/2 collant every two to three weeks no coolant in the oil or on the ground


Check for possible leak. Also check the radiator cap. Inspect the rubber seal for signs of deterioration. Look for signs where coolant had been escaping which would have coolant stains on them.

I have a 97 cadillac deville why does my car over heats? and does one fan suppose to come on?


Change thermostat and use 50/50 coolant mixture only. Add coolant with car running. Fill up radiator, let everything go into engine, then add more until it is completely full. Fans only come on when car is idle for a period of time while stopped.
