On my 09 Hhr ss when I turn on the a/c the belt squeals only when I take off from a low rpm in park at a light.
Another words If you are driving along even at 10 MPH and you turn the ac on no noise.
But If it is on and you stop at a light then accelerate away from the light it will squeal for about a second.
I was going to just change the belt But after reading on here I see it could be
Ac pump
Ac clutch
Tensioner etc.
Just wondering what others have found in tjis situation.
56000 miles.
Maybe I will have dealer look at since it's under warranty But I really don't want to pay $100 for a belt change

 

I changed the belt out, you will need a belt tentioner tool as there is no enough room to get a rachet or -bar inbetween the tentioner and frame, took all of 15 minutes

 

Ya I remember changing the one on my 07 2.4l (traded in for SS)
It seemed to take forever finally I got it on then come to find out after cross referencing the numbers that that Advance auto gave me the wrong one. My car was built in 4/07
Come to find out 08 and up took a 1/2" longer belt swapped the belt in 5 minutes.
Just changed a belt on a customers ford taurus.that was squealing like crazy the belt did not have much mileage but it had age against it.
I was more asking I guess if people have found that with the HHR's , the SS's in particular have issues with ac pumps or idlers more than just belts.
If there is nothing that really stands out then I guess it makes sense to swap a belt out and go from there.

 

Hmmm interesting. My car will only move forward from a stop light in D, I or L. Guess I better have it checked. (j/k, ya know).

 

He's got one of them quantum shifters. He is both parked and moving depending on when you observe him.

 

Great now my secret is out about my quantum shifter.
now everyone is going to want one.But you do end up with a squeaky belt.
