Question about 1992 Cadillac DeVille
I just replaced the water pump and the system seems to be working fine, but the coolant temp light still turns on for about 30 sec then shuts! I took the engine temp at about 215 at the thermostat. Do you have any idea what is wrong? Thanks
Replace the thermostat. When the water pump went bad, you over heated the car. Once over heated, thermostats are always no good. They operate on the expansion of a wax pellet, and overheated, some wax escapes. So it will never fully open again.

Some models have a bleeder valve located on or near the thermostat. Not all manuals will show this vital component. If yours has one( if your coolant recovery bottle is above highest point of radiator you do) you need to bleed the air out of your cooling system. Do this by opening the valve until coolant comes out. Do this a couple of times as your car is getting to operating temp. should solve your problem.
