Refrigerant: Application and ID
Identifying R-134A and R-12 A/C Systems
To determine which types of A/C system a particular vehicle has, inspect the A/C system's major components and refrigerant lines for special tags. If
the system has yellow R-134a NON-CFC" tags, it is an R-134a system and uses R- I 34a refrigerant. If there are no special R-134a N0N-CFC" tags on
the A/C system components or lines, the system uses R-12. R-134a systems can also be identified by the brown-colored O-rings (HNBR) use
throughout the A/C system.
