2001 Alero, 3.4 GL 97,000 Mi
I read through all the posts and there doesn't seem to be a same exact problem as what I'm having.
Last year while driving down the road I looked down and saw the temp gage dropped to cold. When this happend the rad. fans would run on high speed, with climate control fan off. A few days later the temp gage would read normal (half way mark) and no fans on. So I replace the coolent temp. sensor with a wells sensor. Had no problems until then.
Just last night was driving it and noticed the same thing, the temp gage was on the cold line, fans will startup on high right when the car is first started in the morning with the climate control off.
I was wondering if the coolent temp. sensor failed again or if there could be anything else. I still have a 1 yr. warr. on the sensor and could get another one. I don't know what the resistance is supposed to be on some temps though if I wanted to test it.
Any help would be appriciated
Thank You
