Installation And Service Guidance
Intended for mechanics and experienced DIYers. Follow these general steps and safety precautions:
- Have the vehicle’s refrigerant recovered by a certified technician before removal; do not vent refrigerant to atmosphere.
- Disconnect the battery to prevent electrical shorts.
- Remove the drive belt and any obstructing engine covers to access the compressor.
- Label and disconnect electrical connectors and refrigerant lines; be prepared to replace O-rings and seals.
- Unbolt the compressor from its mounts (three mounting points) and remove it carefully.
- Fit the replacement compressor, use new O-rings, and ensure correct alignment of the pulley and belt routing.
- Charge the compressor with the specified oil amount (135 ml of PAG 46) and follow the vehicle manufacturer’s procedure for vacuuming and recharging the system to the correct refrigerant type and pressure.
- After installation, test for leaks and verify clutch engagement and system pressures during operation. Follow OEM torque figures and service intervals when available.
Common Failure Modes And Causes
Understanding typical causes of compressor failure helps with diagnostics and preventive maintenance:
- Oil contamination or incorrect oil type can reduce lubrication and damage internal components.
- Seal and O-ring deterioration leads to refrigerant and oil leaks.
- Clutch or bearing wear results in noise, poor engagement or pulley seizure.
- System contamination (moisture, metal debris) from other failed components can accelerate compressor wear.
- Electrical faults or wiring/connectors failures can prevent clutch activation.
