I`ve just found this in the manual:
The refrigerant system can remain fully charged
during compressor clutch, pulley, or coil replacement.
Although the compressor assembly must be removed
from its mounting, the compressor clutch can be service
with the compressor in the vehicle.
(1) Disconnect and isolate the battery negative
cable.
(2) Raise and support the vehicle.
(3) Remove the serpentine drive belt. (Refer to 7 -
COOLING/ACCESSORY DRIVE/DRIVE BELTS -
2.4L - REMOVAL) or (Refer to 7 - COOLING/ACCESSORY
DRIVE/DRIVE BELTS - 3.3/3.8L - REMOVAL).
(4) Disconnect the engine wire harness connector
for the compressor clutch coil from the clutch coil pigtail
wire connector on the top of the compressor.
(5) On models with the 3.3L and 3.8L engines, disengage
the retainer on the engine wire harness compressor
clutch coil take out from the bracket on the
top of the compressor.
(6) On models with the 2.4L engine, remove all of
the compressor mounting screws except the upper
left (rear of the compressor) screw, which should only
be loosened. Allow the front (pulley end) of the compressor
to tilt downward far enough to access the
clutch for removal, then tighten the loosened upper
left compressor mounting screw.
(7) On models with the 3.3L and 3.8L engines,
remove the three screws and one nut that secure the
compressor to the engine. Disengage the mounting
ear at the front of the compressor from the stud on
the engine, allow the front (pulley end) of the compressor
to tilt downward far enough to access the
clutch for removal, then reinstall and tighten the
upper left compressor mounting screw.
(8) Remove the compressor shaft bolt (Fig. 13). If
necessary, a band-type oil filter wrench or a strap
wrench can be placed around the clutch plate to aid
in bolt removal.
(9) Tap the clutch plate lightly with a plastic hammer
and remove the clutch plate and shim(s) from
the compressor shaft (Fig. 14). Be certain not to
lose the shim or shims.
CAUTION: Do not pry between the clutch plate unit
and the pulley to remove the clutch plate from the
compressor shaft as this may damage the clutch
plate.
(10) Using snap ring pliers (Special Tool C-4574 or
equivalent), remove the external snap ring that
secures the pulley to the front cover of the compressor,
then slide the pulley off of the compressor (Fig.
15).
(11) Remove the screw that secures the clutch coil
pigtail wire connector bracket and ground clip to the
top of the compressor housing.
(12) Using snap ring pliers (Special Tool C-4574 or
equivalent), remove the external snap ring that
secures the clutch coil to the front cover of the compressor
housing, then slide the clutch coil off of the
compressor (Fig. 16). I hope this is of use to you. Ian
INSPECTION - COMPRESSOR CLUTCH/COIL
Compressor clutch components should always be
inspected closely before they are reinstalled. The
clutch plate and clutch pulley are mated at the factory
using a burnishing operation. No attempt should
be made to separately replace the compressor clutch
pulley or clutch plate. The clutch coil may be serviced
separately.
(1) Examine the friction surfaces of the clutch pulley
and the clutch plate for wear. The clutch pulley
and clutch plate should be replaced if there is excessive
wear or scoring.
(2) Examine the friction surfaces of the clutch pulley
and the clutch plate for oil contamination. If the
friction surfaces are oily, the clutch pulley and clutch
plate should be replaced. Also inspect the shaft and
nose area of the compressor for oil. Remove the felt
packing from around the compressor shaft in the
compressor front cover. If the felt is saturated with
oil, the compressor front shaft seal is leaking and the
compressor will also have to be replaced.
(3) Check the clutch pulley bearing for roughness
or excessive leakage of grease. Replace the clutch
pulley and clutch plate if the bearing is faulty.
INSTALLATION
The refrigerant system can remain fully charged
during compressor clutch, pulley, or coil replacement.
Although the compressor assembly must be removed
from its mounting, the compressor clutch can be service
with the compressor in the vehicle.
(1) Align the dowel pin on the back of the clutch
coil with the hole in the compressor front cover, and
position the clutch coil onto the compressor. Be certain
that the clutch coil pigtail wires are properly oriented
and routed so that they are not pinched
between the compressor front cover and the clutch
coil.
NOTE: A new snap ring must be used to secure the
clutch coil to the compressor. The bevel side of the
snap ring must face outward.
(2) Using snap ring pliers (Special Tool C-4574 or
equivalent), install the external snap ring that
secures the clutch coil to the front cover of the compressor
(Fig. 16). The bevel side of the snap ring
must face outward and both snap ring eyelets must
be oriented to the right or the left of the clutch coil
dowel pin location on the compressor. Be certain that
the snap ring is fully and properly seated in the
groove.
CAUTION: If the snap ring is not fully seated in the
groove it will vibrate out, resulting in a clutch failure
and severe damage to the compressor front
cover.
(3) Install and tighten the screw that secures the
clutch coil pigtail wire connector bracket and ground
clip to the top of the compressor housing.
(4) Install the pulley onto the front cover of the
compressor. If necessary, tap the pulley gently with a
block of wood placed on the pulley friction surface
(Fig. 17).
CAUTION: Do not mar the friction surfaces of the
pulley.
NOTE: A new snap ring must be used to secure the
clutch pulley to the compressor. The bevel side of
the snap ring must face outward.
(5) Using snap ring pliers (Special Tool C-4574 or
equivalent), install the external snap ring (bevel side
facing outward) that secures the clutch pulley to the
front cover of the compressor (Fig. 15). Be certain
that the snap ring is fully and properly seated in the
groove.
(6) If the original clutch plate and clutch pulley
are to be reused, reinstall the original shim(s) on the
compressor shaft against the shoulder (Fig. 14). If a
new clutch plate and/or clutch pulley are being used,
install a trial stack of shims 1.0 mm (0.040 in.) thick
on the compressor shaft against the shoulder.
(7) Install the clutch plate onto the compressor
shaft.
(8) Install and tighten the compressor shaft nut
(Fig. 13). If necessary, a band-type oil filter wrench
or a strap wrench can be placed around the clutch
plate to aid in bolt tightening. Tighten the bolt to
17.5 N·m (155 in. lbs.).
(9) If a new clutch plate and/or clutch pulley are
being installed, the air gap between the clutch plate
and clutch pulley must be checked. (Refer to 24 -
HEATING & AIR CONDITIONING/CONTROLS -
FRONT/COMPRESSOR CLUTCH - STANDARD
PROCEDURE - COMPRESSOR CLUTCH AIR GAP).
(10) On models with the 2.4L engine only, loosely
install the four screws that secure the compressor to
the mounting bracket on the engine. Tighten the
screws to 28 N·m (21 ft. lbs.).
(11) On models with the 3.3L and 3.8L engines
only, loosely install the three screws and one nut that
secure the compressor to the engine. Tighten each of
the fasteners using the following sequence to 54 N·m
(40 ft. lbs.).
†The upper screw at the rear of the compressor.
†The lower screw at the rear of the compressor.
†The lower screw at the front of the compressor.
†The upper nut at the front of the compressor.
(12) On models with the 3.3L and 3.8L engines
only, engage the retainer on the engine wire harness
compressor clutch coil take out with the bracket on
the top of the compressor.
(13) Reconnect the engine wire harness connector
for the compressor clutch coil to the coil pigtail wire
connector on the top of the compressor.
(14) Reinstall the serpentine accessory drive belt
onto the front of the engine. (Refer to 7 - COOLING/
ACCESSORY DRIVE/DRIVE BELTS - 2.4L -
INSTALLATION) or (Refer to 7 - COOLING/ACCESSORY
DRIVE/DRIVE BELTS - 3.3L/3.8L - INSTALLATION).
(15) Lower the vehicle.
(16) Reconnect the battery negative cable.
(17) If a new clutch plate and/or clutch pulley are
being installed, the new clutch components must be
burnished. (Refer to 24 - HEATING & AIR CONDITIONING/
CONTROLS - FRONT/COMPRESSOR
CLUTCH - STANDARD PROCEDURE - COMPRESSOR
CLUTCH BREAK-IN).

U need a speacial tool clutch tool removel tool
Hi:) For Ford Compressor Clutch Removel
Step 1
Locate and remove the compressor clutch retaining bolt. Looking at the compressor clutch you will see a bolt in the center and three bolts along the outer edge. The center bolt is the retaining bolt. The three bolts around the edge of the clutch can only be accessed after removing the clutch, and are only relevant in clutch repair situations. To remove the retaining bolt you need to maintain the clutch position and relieve pressure from bolt head by applying the compressor clutch holding tool with your other hand, or have an assistant hold the tool in place. Do not lose the retaining bolt in case you need to reference it later.
Step 2
Separate and remove the clutch from the shaft of the compressor. Once the retaining bolt is removed, as described in Step 1, simply pry the clutch away from the mounting surface using your hands. If the clutch is a little difficult to remove due to damage or decay then try using a screwdriver to lightly pry the rear side of the clutch away. Spray the area with an auto lubricant and allow it to sit overnight if needed. While removing the clutch do not lose clutch spacers.
Step 3
Pull the snap ring from the clutch pulley using your snap ring pliers. You will now be able to remove the clutch pulley from the compressor. While everything is apart, and before installing your new compressor clutch, clean the area to remove dust or grime.
Reverse steps to install.
