A/C Compressor System

Compressor Oil Replenishment
Up to 120 ml (4 oz) of refrigerant oil can collect in the crankcase. Therefore, it is important when replacing the compressor that the oil in the old compressor crankcase can be drained and measured. Discard the oil after recording the amount.

All replacement compressors will be shipped with approximately 240 ml (8 oz) of oil in the crankcase. The oil must be drained and retained. Replace the oil in the same amount as previously recorded from the old compressor.
