Refrigerant Oil: Service and Repair

A/C REFRIGERANT SYSTEM OIL CHARGE REPLENISHING

NOTE: Do not mix refrigerant oils. Use of incorrect refrigerant oil will cause compressor failure.

The CVC compressor uses a low viscosity refrigerant oil, GM P/N 12378526 (Canadian 88900060).

If oil was removed from the A/C system during the recovery process or due to component replacement, the oil must be replenished. Oil can be injected into a charged system using J 45037. For the proper quantities of oil to add to the A/C refrigerant system, refer to Refrigerant System Capacities (LA1) or Refrigerant System Capacities (L61).
