Installation Notes and Tips

Ensure the vehicle’s A/C system is fully depressurized before removing the old hose assembly. Verify compatibility with your specific Ford, Lincoln, or Mercury model and year. Use the included green O-rings (part number 24668) to maintain a proper seal and prevent refrigerant leaks. Since this assembly does not include a bracket, confirm mounting points and secure the hose appropriately to avoid vibration or damage. Professional installation is recommended to maintain system integrity and performance.
