Installation Notes and Tips

Verify the vehicle uses R12 refrigerant, V-belt drive, and bolt tangent mounting before installation. Confirm pulley and clutch dimensions match the existing system, and inspect the condenser, receiver/drier, hoses, and seals for contamination or wear before charging the system. Proper evacuation and recharge procedures are important for reliable A/C operation.
