Wife's friends car. She says the warning comes on immediately after starting and the gauge never moves from cold on the dash.

Best I got from Google is that there are 2 temp sensors. One near "the drivers side in a plastic manifold" and the other in the radiator. Can anyone verify the locations before I order the parts? She says it's the 2.5L engine.. hopefully that is accurate.

Only asking for verification because when I call around to part stores they keep trying to sell me a thermostat with the housing, and that doesn't match the description I've been getting

Who needs AC now anyways. just roll down a window.


look on gmpartsdirect.com they have decent parts diagrams of where things are located, but i wouldn't order form them.

what code is being thrown? a GM will set that message anytime there's an error with the cooling system, including when the thermostat isn't allowing the car to come up to temp. make sure the antifreeze is full and if you can get a readout of the ECT.

I'll have to scan it in the morning before I head to the parts store at around 9. I was just going off what she said and the solution from Google haha

IIRC correctly, this is an issue with the 2.5 and yes there are two ECT sensors.

1) tells the PCM what the temp is for fuel trimming.
2) tells the CANBUS what to relay to the dash gauge.

#2 is under the engine cover and while it looks tight it's pretty simple to R&R the sensor. A little retaining clip and it should come out. You shouldn't even lose any coolant in the process. This one fixes both issues (the A/C override and the low temp on the gauge on the dash).

Here is a pic of it.

Pepboys definitely ordered the wrong part.. they got one for the radiator and also the thermostat with the housing....
