Installation Notes and Tips

Verify the vehicle uses an H6 compressor, 6-groove serpentine belt drive, and the listed electrical connector before installation. Confirm refrigerant type and oil specification match the system requirements, and replace the O-rings/sealing washers included in the package during service. Proper evacuation, leak checking, and recharge procedures are required after compressor replacement.
