Installation Recommendations
- Have Refrigerant Recovered: Always recover refrigerant with appropriate equipment before opening the A/C system. This must be performed in accordance with environmental and safety regulations.
- Replace Seals And Lubricant: Fit new O-rings and apply correct PAG oil compatible with the vehicle’s system to prevent leaks and ensure proper lubrication.
- Use Correct Tools And Procedure: Remove any obstructing trim or covers, loosen clamps or connections at the designated joints, separate the two-piece assembly if required, and install the replacement pipe ensuring clean mating surfaces.
- Vacuum And Recharge: After fitting, evacuate the system to remove moisture and air, then recharge to the manufacturer-specified refrigerant charge and pressure.
- Leak And Function Test: Perform a pressure/leak test and run the A/C to verify correct operation and cooling performance.
- Professional Service Recommended For Refrigerant Handling: Recovery, evacuation, and recharge are recommended to be done by a qualified workshop with proper A/C service equipment.
Why This Part Fails Most Often
- Corrosion And Environmental Damage: Exposure to road salt and moisture causes corrosion at joints and fittings, leading to leaks over time.
- Mechanical Impact: Stone chips, debris, or improper handling during repairs can dent or crack the lines.
- Ageing Seals: O-rings and seals harden or deteriorate with heat cycles, causing refrigerant leaks at connection points.
- Vibration And Fatigue: Continuous vibration can weaken crimped joints or connections, especially on older vehicles.
