Refrigerant Oil Distribution

ADDING OIL

Adding oil to the A/C system should take place after recovery and before evacuation procedure. Remove the refrigeration discharge hose at the compressor pipe connection. Pour the correct quantity of new PAG compressor oil into the discharge hose pipe. Always lubricate new O-rings with clean R-12 mineral compressor oil prior to assembly. Then properly connect hose to compressor with new O-ring. For component replacement, add new Saturn refrigerant PAG oil to the component before installation.

OIL DISTRIBUTION

Saturn air conditioning system requires 150 cc of PAG compressor oil. Service compressors have 65 cc of PAG oil installed.

New oil quantities must be added to system during component replacement and conditions stated as follows:

With no signs of excessive oil leakage, add:

A. Compressor: Remove, drain, and measure oil. Drain replacement compressor. Add the same amount of new PAG compressor oil drained from removed compressor to replacement compressor. See AIR CONDITIONING COMPRESSOR for details.
B. Evaporator: Add 67.5 ml (2 1/4 oz.) of new PAG compressor oil.
C. Condenser: Add 22.5 ml (3/4 oz.) of new PAG compressor oil.
D. Receiver-dehydrator: Add 30 ml (1 oz.) of new PAG compressor oil.
