    Thank you for the information, I went and checked to see if both fans came on and they did, I didn't know that the air had to be on. So since both fans come on, what else can make the vehicle overheat.

First i would want to make sure that the fans themselves are in good working order!! You can unplug the fan and run a live wire from the battery to the fan and a ground wire to the fan and see if it is working!! if you have nothing then your fan might be burnt up or the fan is trying to come on but it is so weak that it isnt doing the job the car requires

    your thermostate or a coolant sensor is either bad!! Your air should not have to be on for 1 fan to run!! Sounds like you have a sensor that is bad!! The fastest way to fix your issue is to take to your local repair shop and have a scan done on your car for faulty sensors!! There might be an issue with your thermostate!! But if the sensor doesnt tell the fan to turn on then it doesnt know any better!! I would run with the air on low at least to get the care to a shop with a scanner to fix your issues!! THNX

2002 Cadillac Seville sls starts, idles fine. Going to accelerate have to push it to gain any speed. Have replaced plugs and wires, both oxygen sensors. Now is also overheating


Would be worth checking for a restricted exhaust gas flow. Cats sometimes get partially blocked.

If that is ok. I suggest you ask your question again.

Your title says Deville but your question is about the SLS (Seville). If you are asking about the Seville (4.6L V8) with the Key on and the engine off you should have 41-47psi.
