Check coolant levels ( ck leakage if any ) and radiator fan operation. Fans should go on automatically when appropriate temps are reached. They also should go on IMMEDIATELY when A/C climate is put on AUTO. Hope this helps

My Cadillac Deville, 2002 northstar is running hot........or the temp gage goes up and I have to stop driving..I have a new thermostat,relay switches for the fans,temp control sensor and a new coolant...

Check the fan to see if it is going on. On my 1997 Cadillac Deville Limousine I had to have the 2 fans, and 3 relays replaced, as well as the wiring contacts for the relays at an auto electric shop for about $700 last fall, but it has been running cool since then.

The stereo amplifier stays on in my 97 cadillac deville ALL the time, even after the 10 minute RAP....I have to pull the fuse when the car is off to preserve the battery. How to fix?

It will depend on what kind of amp you have, most amps have a remote, you run a wire from the remote outlet to a positive that comes on when the radio is on generaly it will be the auto antenna hot wire on the radio.
