Having problems with your 1999 Cadillac DeVille ?
SMOKES WHEN STARTING UP SOMETIMES - 1999 Cadillac DeVille
If it is blue smoke, it is oil burning. If it only smokes after sitting, then it is a leaking valve guide(s). If it smokes randomly while running, you have leaking oil control piston ring(s). If the smoke is very heavy and white, that is coolant and your head gasket is the problem.

I have a 1994 Cadillac ETC (Northstar) and just recently had one of the ignition modules replaced because it was missing terribly.

Sometimes when accelerating it would miss and hesitate as well. The other day, I pulled up to a stop light and it just quit. I restarted it and it was running extremely rough, then clouds of smoke poured out from the front, back an

Could a water pump be the reason my car is still overheating after the radiator has been flushed, a new heater core, and a new thermostat. My mechanic says that the anti freeze isn't circulating. After all of these steps my heat is now coming on very hot but then it gets back cool, and the fans are coming on and off by themselves when the car starts to overheat. My mechanic also says that it's not the head gasket because the car , which is a 2002 cadillac deville doesn't have white smoke coming

We have a 1998 cadillac deville and sometimes the ac will blow through the vents normally and then unexpectdly they will start to blow air through the vents ontop of the dashboard. Also, when the coolent temp gets higher above 250,( we have been experiencing the car overheating, and have posted about that as well) it will stop blowing cool air. Charge is good on AC. No need to add freon.
When the cool air ceases, does any air blow? If your air flow ceases (the cooling fans run the entire time the A/C runs normally), your cooling fans might also be malfunctioning. How many times has your car overheated since the September 2008 head ... Cadillac DeVille
