Draining Procedure

Before draining oil, position the compressor verdically (clutch facing upwards) and let it sit for 1 minute.
Position the compressor horizontally, with the ports facing downward, rotate the clutch and shake the compressor in order to remove as much oil from the compressor as possible.
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.
Measure and record the amount of oil drained from the removed compressor. This measurement will be used during installation of the replacement compressor.
Inspect oil drained from removed comperssor. Refer to «Air Conditioning Compressor Oil Diagnosis»(/cadillac/cts/ii-2007-2014/remont/automatic-hvac-system/#heating-ventilation-and-air-conditioning__air-conditioning-compressor-oil-diagnosis)
Properly discard the used refrigerant oil.
