Tools Required

J 39400-A Electronic Halogen Leak Detector

1. Recover the refrigerant. Refer to Refrigerant Recovery and Recharging .
2. Remove the compressor hose assembly nut from the condenser.
3. Remove the compressor hose assembly from the condenser.
4. Remove and discard the seal washer.
5. Remove the evaporator hose assembly bolt from the condenser.
6. Remove the evaporator hose assembly from the condenser.
7. Remove and discard the seal washer.



8. Remove the radiator assembly. Refer to Radiator Replacement in Engine Cooling.
9. Remove the condenser bolts  (2) from the radiator (1).
10. Remove the condenser (2) from the radiator (1).

Notice: 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 P/N 88900060).

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

1. Add PAG oil to the condenser. Refer to Refrigerant System Capacities
