Question
We have a 1998 Cadillac STS. We are having problems with this car running hot! We have replaced the thermostat, radiator hose, and the water pump! Nothing seems to be wrong with the reservior or the radiator. What other things can be wrong with this car? Can the radiator be clogged up?
Hello,
I answer these issues every week. You cannot run a Cadillac engine hot. As you are you are destroying the engine!!!! These had head gasket problems, fan problems, cracked blocks. This is what happens with an aluminum engine compared to a cast iron.
The cooling system may not be circulating, the radiator could be plugged. You need to have this engine serviced now and pray that you have not done irreversible damage. Very common for me to see where one of these turns into a $4,000 engine job.
As I have said. I love Cadillacs, but I also know them very well. They are a nice car until you run into a problem like you have and then they are money pits!!
I guess that is why I just sold my last Caddy before I had an over heating problem and bought a used Chevy truck.
Good Luck!

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?
