how to put freon in ac unit in 1987 chevy celebrity
Pay $85 and have it evacuated, checked for leaks 30mm of vacuum ...and filled with the correct oil PAG,# and amount. Then filled to the correct weight ONLY proper way, of refrigerant 134A. That's what I suggest...unless you have the cans of R12 Then just and through your manifold gauge set to the LOW side of the system.
