HFC-134AA/C System

WARNING: This page is about a different car, the 2003 Subaru Outback, 2003 Subaru Legacy, and 2003 Subaru Baja. However, it is still accessible from the selected car via links, so may be relevant.

Unlike the old conventional HFC-12 system components, the cooling system components for the HFC-134a system such as the refrigerant and compressor oil are incompatible.
Vehicles with the HFC-134a system can be identified by the label "A" attached to the vehicle. Before maintenance, check which A/C system is installed in the vehicle.
