I'm looking to change the Serpentine Belt but I need to know which A/C unit is in the car. Is there a easy way to find out which A/C unit is in the car? I have a 2007 HHR with 125000 miles on it.

Thanks

there is only a 1/2 inch difference, the tensioner will take care of it.

There was a tensioner redesign mid '07, get both belt pn's and return the one that doesn't match up.

Also, with 125k on the clock, changing the tensioner out isn't a bad idea, they have a finite lifespan, and they're reasonably cheap.

I changed mine at Advance Auto they loaned me the tool and ensured I had the correct belt, they even let me wash up afterwards. mine was the shorter Goodyear Gatorback belt, I have a 2007 LT 2.2 liter
