HFC134A Air Conditioning Refrigerant

The 1993 SVX and future Subaru vehicles will have an A/C system which uses HFC134a as the refrigerant. There is no compatibility between R12 and HFC134a. Therefore, you will need special manifold gauges, and refrigerant charge recovery station dedicated for HFC134a.

The change to HFC134a is required to reduce the harmful effects to the atmosphere from CFCs in R12.

Prepare now for this change by sourcing the proper equipment.

Subaru will be releasing more information on this change in the near future.

HFC 134a, chemical name "Tetrafluoroethane", is available.

Caution:
Before servicing, always check the labels on the compressor, radiator support and other A/C components for the type of refrigerant required to properly charge the system.

Label Color:

All R-134a system components are required to have light blue labels indicating R-134a as the only refrigerant to be used in this system. The following components are labeled:

^ Compressor
^ Evaporator
^ Hoses (different charge valves)
^ Condenser
^ Receiver-Dryer
^ Expansion Valve
^ Pressure Switch

Note:
The introduction of any refrigerant other than R-134a will damage system components. The SOA Warranty Department is aware of this information.
