Operation CHARM: Car repair manuals for everyone.

Heating and Air Conditioning: Application and ID

Refrigerant System:
Vehicles equipped with R-134a A/C systems can be identified as follows:
- Sticker in engine compartment or on condenser indicating "R-134a" or "CFC-free refrigerant"
- New service valve connection on condenser.

NOTE: All repairs for A/C, heating and ventilation components that do not affect the refrigerant system are the same as those for R-12 equipped vehicles.
