2001 GP Overheating

[lotsofun333]

The intake gasket was replaced about a year ago....do you think it could be bad again already

If the car is overheating wouldn't it be gurgling, boiling and steaming ....or at least one of those!! It's not doing that. When you turn a car off that's overheating, it's been my experience that it does all of the above.

Hubby is now saying he thinks it is a faulty sensor because it's acting completely different than the other sensor did. ??? EVEN THOUGH it's brand new. He now says it's not a Delco
He replaced the ECT thinking it would make the Low Coolant Temp light go out. This didn't work (obviously). Until he read some other threads from this site he didn't even know the low coolant temp sensor even existed. It works now. The "dummy light" on the dash went out.

Without the a/c running before he changed the ECT it didn't overheat unless it sat in a parking lot for a long time w/the a/c on. As long as we were driving it was fine....and the faster we drove the cooler the car would run.

He did go bleed the cooling system and it's pumping water fine. It shot a stream of anti-freeze out...there was no air in it.

Sounds like you are on the right path. The ECT sensor has a big question mark at this time. Stick with an AC Delco brand because they are better calibrated for the input the Powertrain Control Module (PCM) requires in order to properly display temperature at the gauge and control the cooling fans.

TYVM for all of your help. We will let you know the outcome as soon as the temperatures OUTSIDE cools down some from 114 degrees!! My husband will then change the ECT once again.
