Ford 4C3Z-19860-AB Air Conditioning Evaporator Core

The tube lock coupling clip should be removed, and the spring lock coupling disconnect tool should be installed over the spring lock coupling. The tool should be pushed to the right to disengage the female fitting from the tube lock coupling spring. The technician should then carefully pull the tube away from the evaporator, ensuring that no debris enters the system. It is important to inspect the O-rings for any signs of wear or damage and replace them if necessary to prevent leaks during reassembly. Always follow the manufacturer's guidelines for proper disconnection and handling of refrigerant lines to ensure safety and system integrity.
