Engine Cooling problem
2003 Pontiac Grand Prix 6 cyl Front Wheel Drive Automatic 70,000 miles
I read through your FAQ's and believe I have narrowed the solution to my problem down to the coolant temp sensor but one thing leaves me unsure.
Niether of the cooling fans run under normal operation. I turn the A/C on and they kick on and off as they should so that tells me the relay and the motors are good. What has me unsure about the coolant sensor being the culprit is the fact the water temp gauge seems to be acurate. Is there a seperate sending unit for the water temp gauge? Or could the indication portion of the sensor still be functioning yet not sending a signal to the relay to kick the fans on?
have the same problem?
