Draining Procedure

WARNING: This page is about a different car, the 2015 Chevrolet Trax and 2015 Buick Encore. However, it is still accessible from the selected car via links, so may be relevant.
    NOTE:

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

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