I have been unable to find an answer to this question, and called Chevrolet for information. The representative with whom I spoke asked if I had installed genuine Chevy parts and, when I said "No", immediately lost interest. I haope that you can help: I have overhauled the dual-air (front and back) conditioning system and converted to R-134. How much freon does the conversion take?
