What is the recommended ACDelco Coolant Temperature Sensor to use on 2007 HHR LT?
My mechanic is going to replace thermostat and temp sensor.

found
ACDelco 131-158 Gm Original Equipment Thermostat

ACDelco 213-4514 Professional Engine Coolant Temperature Sensor
ACDelco 213-4333 GM Original Equipment Sensor (use together with mating connector PT1798)

thanks

 

The 213-4514 doesn’t require the adapter harness, I would use that, my question is why replace the sensor , not common that they fail, a P0128 code points to the thermostat which you state the correct part.

 

I also think the sensor replacement is questionable from what I have gathered.
But since it's not terribly expensive and since he will charge me the same if I replace it or not I'll just do so.
Also my car is pretty old and probably could use the new part.

I'll just go ahead and get the part # you indicated.

thaks

 

Your welcome, the thermostat is easy to change just 2 , 10mm bolts
