Question
How are you rob hope all is well I just bought a 96 cadillac sedan deville
and it seems to be overheating I changed the radiator & the problem
remains the same I took the thermostat out it was no good and it
continues to overheat it reaches temperatures to about 250 to 270
depending on the amount of time I drive I don't know what else to do I
have five kids and I just bought the car to get from point a to point b
please help with any advice
Hello,
Of all cars to buy and to need reliable transportation for the kids, this is not the car you should have bought.
I try to warn people about these junk aluminum engines when there are overheating issues. If you look in my archives its all there.
I wish I could give you good news, but there is never good news on these engines that have been run hot. You won't find a good used engine because chsnces are about 99% the engine in the car in the junkyard was overheated too.
This could get real expensive fast and from your discription at the least you need head gaskets and it just gets worse.
Somebody saw you coming!
See anything you do like changing the radiator, thermostat, its too late. This engine gets above 230 degrees and it is self destructing!
Cadillac has used aluminum engines since 1982, all with the same end once overheated. New engine will cost $4-5,000 and not worth putting in a 1994.
The only option you have is to unload it on someone not familiar with the issue.
I would love to give you better news, but there is none. You are not the only one that has been ripped off by Cadillac's engineering team, but Cadillac makes money on replacement engines.

Expertise
Alarm system questions cannot be answered on this forum. These systems are not what I can answer. Without being physically at the vehicle and not knowing what kind of electrical service has been done on the vehicle, there is no possible way to give an accurate answer over the internet. My expertise is in Ignition/key based anti-theft systems. These issues include GM VATS (resistor chip in key blade) PASSLOCK (MRD)-ignition lock rotation based, no special ignition key and the PKIII Transponder (computer chip in key) systems. These systems are not alarm based and are integral with the starting of the engine. This is why I cannot diagnose alarm problems without physically looking at the vehicle: Alarm systems are a completely different annimal than ignition key/lock based anti-theft system. Many alarm questions come from vehicles 10 years old, and since older, many hands that had been involved over the years.I am an expert in all GM factory (ignition/key based)systems. Alarm system questions pose to many situations beyond my knowledge as to what has been done to the vehicle over the years. Some guy may have actually wired the stereo into the alarm system. Who knows? Over my past 30 years in vehicle wiring repair, I have seen unbelievable wiring disaters done by guys that consider themselves "mechanics." I have seen stereos and alarms intalled using surgical tape. I have seen modules burn up, un-fused circuits, wiring jambed between the doors and even lamp cord used for a starter kill. To answer alarm questions over the internet without examining the vehicle is like asking; What does it take to remove a dent?
