Air Conditioning Compressor Replacement

A new compressor is supplied filled with a full charge (X cm³ ) of refrigerant oil.

A calculated quantity of oil must be drained from the new compressor before fitting. To calculate the quantity of oil to be drained:

1. Remove the drain plug from the old compressor.
2. Invert the compressor and gravity drain the oil into a calibrated measuring cylinder. Rotate the compressor clutch to ensure the compressor is completely drained.
3. Note the quantity of oil drained (Y cm³
4. Calculate the quantity of oil to be drained from the new compressor using the following formula:X cm ³  - (Y cm ³  + 20 cm ³  ) = Q cm ³
