Air Conditioning Compressor Oil Balancing Delphi

Important: Drain and measure as much of the refrigerant oil as possible from the removed compressor.

1. Drain the oil from both the suction and discharge ports of the removed compressor into a clean, graduated container.

Rotate the compressor shaft to assist in draining the compressor.




2. Measure and record the amount of oil drained from the removed compressor.

This measurement will be used during installation of the replacement compressor.

3. Properly discard the used refrigerant oil.

Important: The refrigerant oil in the A/C system must be balanced during compressor replacement.

1. The replacement compressor is shipped without refrigerant oil.



2. Calculate the amount of refrigerant oil required for oil balancing.

Compare the following refrigerant oil capacities:

•	The amount drained and recorded during compressor removal.

•	The amount recommended for component replacement. Refer to Refrigerant System Capacities .

3. Add the greater amount of refrigerant oil to the A/C compressor.

Air Conditioning Compressor Oil Balancing Sanden

Important: Drain and measure as much of the refrigerant oil as possible from the removed compressor.

1. Before draining oil, position the compressor verdically (clutch facing upwards) and let it sit for 1 minute.
2. Position the compressor horizontally, with the ports facind downward, rotate the clutch and shake the compressor in order to remove as much oil from the compressor as possible.
3. Drain the oil from both the suction and discharge ports of the removed compressor into a clean, graduated container. Rotate the compressor shaft to assist in draining the compressor.



4. Measure and record the amount of oil drained from the removed compressor. This measurement will be used during installation of the replacement compressor.
5. Properly discard the used refrigerant oil.

Important: The refrigerant oil in the A/C system must be balanced during compressor replacement.




1. Before installing the compressor, the refrigerant oil will have to be fully drained.
2. Add back the same quantity of polyalkylene glycol (PAG) oil as drained from the removed compressor.

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