Compressor Oil Level Check

In order to add oil to an operating compressor, check the compressor oil using the following procedure:

1. Stop the engine, discharge the refrigerant, and dismantle the compressor from the vehicle.
2. Pour oil from the system line outlet.






NOTE: If the compressor is cold, sometimes it can be hard to drain the oil. Warm the compressor (approx. 40 - 50 °C) to drain the oil.

3. Check the volume of the discharged oil. If it is less than 70 cc, it means there is a leak. Perform the leakage test on each system connection, and repair or replace faulty parts if necessary.




4. Check the oil for contamination and replenish the oil level in the following procedure:




a. When oil is clean
b. If the oil is contaminated with metal fragments or other material, clean the receiver drier after charging the refrigerant.
