Balancing Procedure

WARNING: This page is about a different car, the 2004 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.
    IMPORTANT: The refrigerant oil in the A/C system must be balanced during compressor replacement.
    Follow the balancing instructions provided with the compressor.
  1. The replacement compressor is shipped without refrigerant oil.
