A/C Refridgerant R-134A

In an effort to avoid use of ozone-depleting CFC refrigerants, Kia Motor Company has introduced a new refrigerant system for its vehicles (1998 - xxxx). This system uses non CFC-based refrigerant R-134a.

This new type of refrigerant has many of same properties as R-12 and is similar in form and function. R-134a is a hydrofluorocarbon (HFC)-based refrigerant, however, R-12 is a chlorofluorocarbon (CFC). With no chlorine atoms in its molecular structure, use of R-134a refrigerant will not have any harmful effects on atmosphere's ozone layer.

In order to determine which type of A/C system a particular vehicle has, inspect the A/C system major components and refrigerant lines. If the system has yellow R-134a NON-CFC tags, it requires R-134a refrigerant only.

CAUTION: R-12 and R-134a components are not interchangeable. Mixing components from these two types of system will cause component failure and damage the A/C system.

Do not add R-12 refrigerant to a system requiring R-134a. The two refrigerants are not interchangeable.
