We need help with an overheating problem on our 1999 Cadillac DeVille. We've replaced many parts and wonder if it may be air in the cooling system. Please help.


Could be.
Has the thermostat been replaced ?
You could run the engine without the radiator cap to see if the system has air pockets.
A restriction in the exhaust could cause the engine to run hotter on the road than on short trips.

Temp got up to 230 on my 99 cadillac deville is that normal


Make sure your engine is breathing properly, by regularly changing air filters. Flush your cooling system once each year and pressure test. There are cooling lines that cross over the rear of the engine that get corroded and may begin to weep antifreeze..you can view these lines by removing the engine cover....if you've had a consistent odor of antifreeze after running,with no drippage evident, this area is probably the culprit.....love my 99...
