• Oil type: PAG46 (pre-filled at factory).
• Pulley: 6 grooves, 140 mm diameter for OEM belt compatibility.
• Recommended refrigerant charge: fill to approximately 70–80% of system capacity during installation.

How should I install and prepare the system for best performance?

Before fitting the compressor, thoroughly flush the A/C lines and condenser to remove debris and metal filings that cause premature failures. Install the compressor with new O-rings and the correct refrigerant level after vacuuming the system to specification to avoid contamination and ensure long life.

• Clean cooling system pipes to remove sundries and metal shavings prior to installation.
• Vacuum and leak-test the A/C system, then charge refrigerant to ~70–80% of capacity.
• Replace receiver/drier and expansion valve if the system had contamination or a failed compressor.
• Compare mounting points and electrical connectors with your old compressor before installation.

What performance and durability can I expect?

This compressor is built to provide quick temperature recovery and operate with reduced noise and vibration compared with worn original units. Proper installation and clean system components are essential to achieve the expected lifespan and efficient operation.

• Delivers rapid cooling through strong compressed pressure to restore cabin comfort.
• Designed for low noise and minimal vibration under normal driving conditions.
• Efficient operation can help maintain fuel economy when driving at steady speeds.
