Refrigerant Oil: Service and Repair



Refrigerant Oil Adding

1. A new replacement A/C compressor contains 150 ml (5 oz.) refrigerant oil. If the amount of oil drained from the removed A/C compressor is between 90 and 150 ml (3 to 5 oz.), pour the same amount plus 28 ml (1 oz.) of clean oil into the new A/C compressor. If the amount of oil drained from the old A/C compressor is greater than 150 ml (5 oz.), pour only 150 ml (5 oz.) of clean refrigerant oil into the new A/C compressor. If the amount of refrigerant oil drained from the old A/C compressor is less than 90 ml (3 oz.), pour 90 ml (3 oz.) of clean refrigerant oil into the new compressor.
- When replacing components of the air conditioning refrigerant system, add oil to the replacement components.
