Have you checked the rad to see if you are getting good antifreeze circulation. You may need a new water pump if the circulation is poor. Check to see if all you rad fins are tight & in good shape. It could be the radiator is losing it's efficiency & may need replacement. Hope this helps you. Good luck!

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...

I have a 99 camaro V6. About 3 weeks ago it started running hot. I replaced the thermostat and flushed the radiator and added more coolant. The tempature passes 260 and the fan comes on after like 5...


i have the same problem. it may be a good idea to try and flush all the hoses individually. are you seeing any yellow mustard like gunk on your radiator cap? i took off my water pump and everything seems to be ok with it. here's a few things to check up on. the water pump, the radiator cap may need to be replaced because it may be losing pressure. could be a crack in the radiator, or a soft/week hose. you could take it to a shop and have them do a pressure test to help narrow down the problem.

Why does my 2001 cadillac deville keep running hot. ive changed the water pump and the thermistat


Well there could be a couple of problems if you live in a hot place you should change the thermostat to a lower tempatured one so the water will circulate sooner that will help it run cooler if that doesn't do it it might need the radiator flushed.

No heat


the temp is controlled by a blend door near the heater core and A/C evaporator core deep inside the dash, the blend door has an electric motor called a stepper motor, it has failed, so whenever the door was when it failed is where it will stay, in your case cold air position, to change this part the dash assembly must be removed.
