4. Remove electrical connector from A/C pressure cut-off switch.
5. Raise vehicle on hoist.





6. Remove lower radiator air deflector.





8. Disconnect A/C manifold and tube from A/C condenser core inlet tube. Plug the lines to prevent dirt and excessive moisture from entering.
9. Lower vehicle.
10. Remove the A/C manifold and tube from vehicle.
11. Remove A/C pressure cut-off switch from A/C manifold and tube.

INSTALLATION
1. Install A/C pressure cut-off switch to A/C manifold and tube.
2. With protective caps installed, position the A/C manifold and tube in vehicle.
3. Raise vehicle.




4. Connect A/C manifold and tube to A/C condenser core inlet tube using new O-ring seals lubricated with clean Motorcraft YN-12b refrigerant oil or equivalent meeting Ford specification WSH-M1C231-B. Refer to Peanut Fitting illustration.
5. Install lower radiator air deflector. Tighten three splash shield-to-radiator screws to 7-11 N.m (62-97 lb-in) and remaining 11 screws to 2-3 N.m (18-26 lb-in).
