Draining Procedure

WARNING: This page is about a different car, the 2003 Pontiac Aztek and 2003 Buick Rendezvous. However, it is still accessible from the selected car via links, so may be relevant.

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.
