Overcooling??

I have a 1992 Pontiac Sunbird, and i just wanted to know if it was overcooling because the temperature shows that it barely moves off of 100 degrees...it almost never reaches the 140 mark.
Thanks!!!

Yes! It sounds like the thermostat is stuck open and not allowing the engine to reach operating temperature. You can also have a bad temp. sensor so you may want to replace that too.

alright, thanks!!
