Refrigerant Oil

Draining Procedure

Note: Drain and measure as much of the refrigerant oil as possible from the rear head ports of the REMOVED air conditioning compressor.

1. Drain the refrigerant oil from the crankcase and rear head ports into a clean, graduated container.
2. Rotate the air conditioning compressor shaft to assist in draining the air conditioning compressor.

3. Measure and record the amount of oil drained from the removed air conditioning compressor.
   This measurement will be used during installation of the replacement air conditioning compressor.
4. Inspect oil drained from removed air conditioning compressor. Air Conditioning Compressor Oil Diagnosis
5. Properly discard the used refrigerant oil.
6. Clean the graduated cylinder.
Note: Drain and measure as much of the refrigerant oil as possible from the rear head ports of the NEW air conditioning compressor.

7. Drain bolt and drain the refrigerant oil from the air conditioning compressor crankcase and rear head ports into a clean, graduated container.
8. Rotate the air conditioning compressor shaft to assist in draining the air conditioning compressor.

Balancing Procedure

Note: The refrigerant oil in the air conditioning system must be balanced during compressor replacement.

The replacement air conditioning compressor is shipped with 40 ml (1.4 fl. oz) of refrigerant oil.

1. Refer to the amount of refrigerant oil recorded during the air conditioning compressor removal.

2. If the amount of oil recorded from the removed air conditioning compressor is less than or equal to 40 ml (1.4 fl. oz), add 41 ml of the new PAG oil back into the new air conditioning compressor through the air conditioning compressor suction port.
3. If the amount of oil recorded from the removed air conditioning compressor is greater than 40 ml (1.4 fl. oz), add the equivalent amount of the new PAG oil back into the new air conditioning compressor through the air conditioning compressor suction port.
4. Rotate the air conditioning compressor clutch driver three times to lubricate the internal air conditioning compressor components.
Note: If additional air conditioning components are replaced during air conditioning compressor replacement, add the PAG oil directly to the air conditioning compressor to compensate the air conditioning system.

5. If necessary, refer to Refrigerant System Specifications.
