CAUTION: Do not add R-12 refrigerant to an A/C system that requires the use of R-134a refrigerant. Also, do not add R-134a refrigerant to an A/C system that requires the use of R-12 refrigerant. These two types of refrigerant should never be mixed. Doing so may cause damage to the A/C system.
NOTE: R-12 refrigerant and refrigerant oil is not compatible with R-134a refrigerant and R-134a refrigerant oil.
In an effort to avoid the use of Chlorofluorocarbon (CFC) refrigerants that may harm the ozone layer of the atmosphere, Ford Motor Company has introduced a new refrigerant system that requires the use of a non-CFC-based refrigerant known as R-134a. This new type of refrigerant has many of the same properties as R-12 and is similar in form and function. However, R-134a is a hydrofluorocarbon-based refrigerant while R-12 is a CFC-based refrigerant. Because of the absence of chlorine in its molecular structure, the use of R-134a refrigerant will not harm the ozone layer.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
