Balancing Procedure

WARNING: This page is about a different car, the 2017 Chevrolet Spark. However, it is still accessible from the selected car via links, so may be relevant.
  1. Before installing the air conditioning compressor, the refrigerant oil will have to be fully drained.
    NOTE: The refrigerant oil in the air conditioning system must be balanced during air conditioning compressor replacement.
  2. Add back the same quantity of polyalkylene glycol (PAG) oil as drained from the removed air conditioning compressor. Refer to the amount of refrigerant oil recorded during the air conditioning compressor removal.
