Installation Notes and Tips

Verify the vehicle’s refrigerant specification, pulley style, and mounting layout before installation. Confirm the application details for Chevrolet Cobalt, Chevrolet HHR, Pontiac G5, Saturn Ion, Chevrolet Cavalier, or Pontiac Sunfire models, especially where notes specify CVC type or a 5-groove pulley. Replace contaminated refrigerant oil as required by the service procedure, evacuate and recharge the system correctly, and inspect related components such as the condenser, expansion device, and receiver/drier or accumulator.
