Car Forum / Driving, Maintenance, Tuning / Maintenance and Repair / August 2008Does the thermostat need replaced?
I have a 2001 Chevy Impala. The temp gauge is reading at the bottom and won't budge, even after I drive for an hour. Also, the A/C doesn't work and this morning I tried to drive it again and the check engine light came on about 10 miles down the road. Someone suggested the thermostat, any other suggestions? > I have a 2001 Chevy Impala. The temp gauge is reading at the bottom and > won't budge, even after I drive for an hour.

Have you verified that the thermostat is stuck open? Do you have hot heat inside after driving the car for a while? Is the top radiator hose hot or just warm? If the guage is accurate, chances are the thermostat is stuck open. How many miles are on the car? D >I have a 2001 Chevy Impala.

Could be a bad temperature gauge or sensor. Could indeed be a bad thermostat. Could be a loose wire or a blown fuse. The AC is almost certainly a different issue. The check engine light might be a third issue, but get the temperature gauge or the thermostat fixed first. --scott  Signature"C'est un Nagra.

I would be surprised that the engine stayed cool enough not to even register a temp at all on the gauge. Especially in summer. Feel the hoses and see if they are hot. If they are then check the wiring on the temp sensor and / or replace the temp sensor. Steve B. > I have a 2001 Chevy Impala.

I suggest you give a better description of the A/C and "check engine light" problems including whether their mentions are supposed to be somehow related to the temp gauge problem. |
