My temperature would "stick" sometimes. Say I park the car for 10 hours, it will start at 200F. It would only do it once a while and it wouldn't get hotter. Now it's getting worse and now reaches past* 260F. I worked on it tonight by changing the thermostat, letting the air out, and buying a new sensor. Still the same results. There is no steam,nor water bubling. Infact the Antifreeze isn't even hot enough to make tea to the Touch*. My sense is telling me it's a broken instrument? It's a 2004 SS.


Any thoughts?

Thank-you

 

this forum is so messed up right now, just wait and see, hopefully it will be up and running smooth soon!!

 

Did you check the system's pressure? If the radiator's cap is bad it could lead to overheating/erroneous reading! Also, you may want to check the integrity of the heads/manifold gaskets for air leaks! If you're getting air in the system but no leakage anywhere, a gasket maybe allowing air in and causing the system to overheat.

 

It's possible that it's just a faulty gauge, it's a common problem on our 6th gens.

If nothing is mechanically wrong, it could be your gauge cluster.
