Common A/C Problems This Part Can Address

• Loss of cabin cooling from compressor wear or internal failure
• Noisy compressor operation in an HR6 or DA6 system
• Refrigerant leakage at the suction port or sealing surfaces
• Incorrect compressor fitment after prior repair work
• High-pressure switch-related A/C system faults

Installation Notes and Tips

Verify the vehicle uses an HR6 or DA6 compressor setup before ordering. Match the refrigerant oil type to PAG 150 and confirm the system is set up for R134a service. Because the clutch is not included, reuse or source the correct clutch components separately if required by the vehicle. Inspect the mounting style, metric thread connections, and suction port block-mount design before installation. Replace the O-rings and sealing washer during service and evacuate the system before recharging.
