‌How to Install a Car Air Conditioning Compressor

‌1. Safety Preparation and Oil Adjustment‌

• ‌Disconnect the battery‌ and wear safety gear (gloves and goggles)‌
• ‌Adjust compressor oil levels‌: Drain residual oil from the old compressor and calculate the required oil volume for the new compressor using the formula:New compressor oil capacity – Residual oil from old compressor = Oil to be drained from the new unit‌
• Use ‌ND-OIL8‌ or equivalent compressor oil to lubricate O-rings and fittings‌

‌2. Removing the Old Compressor‌

• Release the ‌serpentine belt‌ by loosening the tensioner pulley‌
• Disconnect ‌electrical connectors‌ and refrigerant lines (suction/discharge ports)‌
• Remove mounting bolts (note torque specifications for reinstallation) and detach the old compressor‌

‌3. Installing the New Compressor Assembly‌

• Mount the new compressor using ‌E8 spline sockets‌ and tighten bolts to ‌9.8 N·m‌ initially‌
• Secure the assembly with additional bolts/nuts, ensuring a final torque of ‌25 N·m‌ as per the manufacturer’s diagram‌
• Reconnect electrical terminals and ensure proper alignment with the engine bracket‌

‌4. Connecting Hoses and Belts‌

• Remove PVC insulation tape from hoses and apply compressor oil to O-rings before installation‌
• Attach ‌discharge and suction hoses‌ with new O-rings, tightening fittings to ‌9.8 N·m‌‌
• Reinstall the ‌multi-ribbed belt‌ and adjust tension for smooth operation‌

‌5. Evacuation and Refrigerant Charging‌

• Use a ‌vacuum pump‌ to evacuate the system for ‌30–60 minutes‌ to remove moisture and air‌
• Charge refrigerant (e.g., R134a) according to the vehicle’s specified capacity, measured with a precision scale‌

‌6. Final Checks and Testing‌

• Start the engine and run the AC at maximum cooling to verify clutch engagement and cold airflow‌
• Inspect for leaks using a ‌UV dye kit‌ or electronic detector‌
• Reinstall protective covers (e.g., air deflectors and underbody panels) and confirm no abnormal noises‌
