The procedure is similar for both ford and Lincoln car models:-----

F150 1/2 ton P/U 2WD/ 4WD
F250 Super Duty P/U 2WD/4WD
F350 Super Duty P/U 2WD/4WD
F450 Super Duty P/U 2WD/4WD
F550 Super Duty P/U 2WD/4WD

And Lincoln Mark model.

Removal & Installation
4.2L ENGINE
4.6L & 5.4L ENGINES:---

WARNING
If installing a new air conditioning compressor due to an internal failure of the old unit, you must carry out the following procedures to remove contamination from the air conditioning system.



If A/C flushing equipment is available, carry out flushing of the air conditioning system prior to installing a new air conditioning compressor. For additional information, refer to Evacuating and Charging.
If A/C flushing equipment is not available, carry out filtering of the air conditioning system after a new air conditioning compressor has been installed. For additional information, refer to Evacuating and Charging.
Install a new evaporator core orifice, as directed by the A/C flushing or filtering procedure.
Install a new suction accumulator as directed by the A/C flushing or filtering procedure.


NOTE
If installing a new A/C compressor, the A/C clutch disc and hub, A/C compressor pulley and A/C clutch field coil must be inspected and transferred from the old unit to the new unit if suitable for reuse.


NOTE
Installation of a new suction accumulator is not required when repairing the air conditioning system except when there is physical evidence of system contamination from a failed A/C compressor or damage to the suction accumulator.

All vehicles:
  1. Raise and safely support the vehicle.
  2. If flushing of the refrigerant system has not been carried out, recover the refrigerant. For additional information, refer to Evacuating and Charging.
  3. Remove the drive belt from the A/C compressor pulley.
6.0L diesel vehicles:
  1. Remove the cooling fan stator assembly. For additional information, refer to Cooling Fan Stator R&I.
4x2 vehicles:
  1. Remove the RH fender splash shield.
All vehicles:
  1. Loosen the bolt and detach the compressor manifold and tube from the A/C compressor. Discard the O-ring seals.

  5. Remove the bolts and the A/C compressor.
  6. To install, reverse the removal procedure.

    If a new A/C compressor is to be installed, the clutch assembly must be transferred from the old unit to the new unit. For additional information, refer to Clutch and Clutch Field Coil in this section.
    Install new O-ring seals.
    If filtering of the refrigerant system is not to be carried out, lubricate the refrigerant system with the correct amount of clean PAG oil. For additional information, refer to Evacuating and Charging.
    Compressor bolts: 25 Nm (18 ft. lbs.).
    Compressor manifold bolt: 20 Nm (15 ft. lbs.).
  7. If filtering of the refrigerant system is not to be carried out, evacuate, leak-test and charge the refrigerant system. For additional information refer to Evacuating and Charging.
