Refrigerant Oil: Service and Repair
Refrigerant Oil Adding
Refrigerant Oil Adding
NOTICE: During normal Air Conditioning (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 refrigerant 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 refrigerant oil is lost due to a hose rupture/separation or other damage, the total system refrigerant oil capacity must be
added.
b The amount specified may be used for one or multiple O-ring leak repairs. Do not multiply the refrigerant oil amount by the number of O-ring leaks
being repaired.
Refrigerant Oil Adding for New A/C Compressor Without Clutch Installation
NOTE: Service A/C compressors are shipped without refrigerant oil.
1. Rotate the old A/C compressor shaft 8 to 10 full rotations (clockwise) while collecting the refrigerant oil in a clean measuring cup.
-
Add the same amount plus the amount collected during refrigerant recovery.
