Refrigerant Oil: Service and Repair

Refrigerant Oil Adding

Refrigerant Oil Adding

NOTE:  During normal A/C operation, oil is circulated through the system with the refrigerant, and a small amount is retained in each component. If
certain components of the system are removed, some of the PAG oil will go with the component. To maintain the original total oil charge, it is necessary
to compensate for the oil lost by adding oil to the system with the new part.

1. Refer to the chart below for refrigerant oil adding amounts and methods of installation.

a

If an excessive amount of PAG oil is lost due to a hose rupture/separation or other damage, the total system PAG oil capacity must be added.

b

The amount specified may be used for one or multiple O-ring leak repairs. Do not multiply the PAG oil amount by the number of O-ring leaks
being repaired.

Adding Refrigerant Oil After A/C Compressor Replacement

Service A/C compressors shipped without clutch and pulley

1. Rotate the old A/C compressor shaft 6 to 8 revolutions while collecting oil in a clean measuring device.

-

If the amount of oil drained from the old A/C compressor is between 85-142 ml (3-5 oz), pour the same amount plus 30 ml (1 oz) of clean
PAG Refrigerant Compressor Oil (R-134a Systems) (YN-12-D) WSH M1C231-B or equivalent into the new A/C compressor.
