Retrofitting to R134a
this is what you need to do
- Diagnose and repair all A/C system malfunctions. (Flush system
only if contamination exists).
- Recover the R-12 refrigerant.
- Remove compressor & drain oil from sump.
- Replace receiver-drier with one containing XH-7 or XH-9 desiccant.
- Replace A/C hose fitting o-rings with o-rings compatible
with R134a.
- Change high and low side service ports to R-134a type by
using adapters, new service valves, etc., per SAE J1660.
- Add 14 FL. OZ. ester oil to compressor & install on vehicle.
- Evacuate system (45 minutes min.)
- Charge system with R-134a. (Usually 15-20% less R-134a by
weight will fully charge an R-12 system.)

- Run system to confirm normal operation.
- Install labels to identify that the system has been retrofitted
per SAE J1660.
