What type of refrigerant does a 1986 Oldsmobile Cutlass Supreme air conditioner require?
A 1986 Oldsmobile Cutlass Supreme likely used R-12 (Freon-12) refrigerant in its air conditioning system. However, R-12 is no longer legally manufactured or sold in most places due to its ozone-depleting properties.
If you need to service the AC system, you'll need to use a R-134a retrofit kit and convert the system. Simply adding R-12 is illegal and harmful to the environment. A qualified mechanic should perform this conversion.
