Year: 2006
Make: Chevrolet
Model: HHR

The underhood label is unreadable, and the owner's manual is gone - and the chart on TRB help page does NOT include an HHR--so I google it and still no answer- I'm going to bed...

-------------------------
The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......

Sorry for the delay. Mitchell lists it at .9 pounds.
