Refrigerant Oil: Service and Repair

Refrigerant Oil Adding

NOTE: When separating air conditioning (A/C) connections, cap the open connections immediately. Do not leave open to the atmosphere.

1. A new replacement A/C compressor contains no refrigerant oil.
- When replacing components of the air conditioning refrigerant system, add oil to the replacement components.
- If evidence of a leak is found, source of the leak is to be rectified.
