Try cleaning the battery posts with a solution of salt and water. This tends to take away all of the acid that may have formed on the battery and/or the posts. Or because you seen sparks from the negative cable, you may need to replace the cables

SOURCE: 1998 cadillac deville fans not coming on starts

If your fans are not coming on then your engine is not receiving the signal that it is overheating. This can be caused by bad fans (unlikely they are both out) a bad relay, or coolant temperature sensor. I would start by checking or replacing the temperature sensor as it can become corroded which is what the PCM uses to turn the fans on. Many vehicles use two sensors, one for the gauge and the other for the ECU, make sure you check/replace the right one. It should be a cheaper part and if you are unsure then match the new one with its location; it should be on the intake manifold or near it, generally with one or two wires. I think you will find your problem as they are common failed parts.

Good luck!

If my 1999 cadillac deville goes up to 232 degrees is it overheating?


Outside of radiator is most likely full of dirt,leaves,
bird feathers,etc.
Remove as many things as necessary, & use an air hose
followed by garden hose to clean radiator.

Could try a new thermostat & make sure spark plugs
& basic preventative maintenance is done

Change Power Steering,Trans & Motor Oils
Old fluids won't remove heat well

94 cadillac won't start, even with a jump. Battery is new and inside lights do come on, but vehicle won't start. Any advice? Thanks


Check the starter/solenoid - sounds like either one or both need replacing. If you can get the starter off - you can take it to an Auto Zone or an O'Reilly's to get it tested. I'm not sure of any tests for the solenoid (sometimes it's part of the starter) - some cars also have a starter relay switch. If that's the problems - it's usually cheap & easy to replace.

My 2003 cadillac deville makes 2-3 clicks then it starts, what could that be?


2 possible problems could be low charge on the battery (if it's the original battery it's definitely time for a new 1) a slick serpentine belt could also cause a low charge on the battery. A bad starter will require more and more energy to start the car until eventually it won't start the car at all.

Best way to change a starter on a 2003 Cadillac Deville.


Take it to someone else would be the easiest. On that engine you have to pull the intake. The starter is just under the intake. Not a hard job. I wouldn't call it a job for a beginner.

2003 Cadillac Deville wont start. Not even a clicking noise. They tell me it's the starter. Need to know how to change the starteror can I just change the celinoid to fix yhe problem? Thanks, K


The starter is under the intake manifold. Replace the complete starter. If you go through that much labor, it would be foolish to just replace the solenoid on a 8 year old starter.
