Hose/Line HVAC: Service and Repair

NOTE: Whenever a refrigerant line is replaced. it is also necessary that the suction accumulator/drier be replaced.





REMOVAL
1. Discharge system. Refer to System Discharging and Recovery. Discharging and Recovery
2. Remove nut retaining A/C hose support bracket.
3. Disconnect suction accumulator/drier inlet tube from A/C evaporator core using Spring Lock Coupling Tool and position to improve access to condenser to evaporator tube. Cap refrigerant line and A/C evaporator core to prevent entrance of dirt and moisture.
4. Disconnect condenser to evaporator tube from A/C evaporator core inlet using Spring Lock Coupling Disconnect Tool T81P-19623-G1. Cap A/C evaporator core inlet to prevent entrance of dirt and moisture.
5. Raise vehicle on hoist.




6 Remove lower radiator air deflector.





7. Disconnect condenser to evaporator tube from A/C condenser core outlet tube. Plug the lines to prevent dirt and excessive moisture from entering.
8. Lower vehicle to floor.
9. Remove nut retaining ground strap to radiator coolant recovery reservoir mounting stud and position ground strap aside.
10. Remove screw retaining A/C condenser outlet tube bracket and remove A/C condenser outlet tube bracket from condenser to evaporator tube.
11. Remove retaining screw and condenser to evaporator tube from vehicle.

INSTALLATION
1. With protective caps and A/C charging valve cap installed, route the new refrigerant line.




2. Connect the condenser to evaporator tube to the A/C evaporator 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).
3. Secure condenser to evaporator tube to side rail with retaining screw. Tighten retaining screw to 7.2-10.8 N.m (64-95 lb-in).
4. Install A/C condenser outlet tube bracket. Tighten retaining screw to 7.2-10.8 N.m (64-95 b-in).
5. Install A/C hose support bracket. Tighten nut to 5.2-8.8 N.m (46-77 lb-in).
6. Install ground strap to radiator coolant recovery reservoir mounting stud with retaining nut.
7. Raise vehicle on hoist.
8. Connect the condenser to evaporator tube and suction accumulator/drier inlet tube to A/C evaporator core 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).
9. 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).
10. Lower vehicle to floor.
11. Leak-test, evacuate and charge refrigerant system. Observe all safety precautions.
12. Check the A/C system for proper operation.
