Installation Notes and Tips

Verify the vehicle’s compressor configuration before ordering, including MSC105CA or MSC105C applications where noted. Replace the receiver drier and expansion valve during compressor service, and evacuate the system before recharging with the correct R134a refrigerant amount. Confirm all O-ring and pad-mount connections are seated properly to reduce the risk of leaks.
