HFC-134a Air Conditioning System

Component parts of the cooling system, refrigerant, compressor oil, and other parts are not the same for the HFC-134a system and the older CFC-12 system. Do not interchange parts or liquid. Vehicles with HFC-1 34a air conditioning systems, use only HFC-134a parts that are indicated on a label (A) attached to the vehicle. Before performing any maintenance, verify the type of air conditioning system installed in the vehicle.
