What This Compressor Helps Address

• Refrigerant circulation problems in the A/C system
• Incorrect fitment from a non-OE-style replacement compressor

Installation Notes and Tips

Verify refrigerant type, pulley belt style, clutch diameter, and mounting configuration before installation. Replace the compressor only after the system has been inspected for contamination, leaks, and restricted flow. Proper evacuation, oil balancing, and recharge procedures are important for reliable operation after installation. Confirm vehicle-specific fitment for the exact year and model before ordering.
