DESCRIPTION - CIRCUIT FUNCTIONS
All circuits in the diagrams use an alpha/numeric
code to identify the wire and it's function. To identify
which circuit code applies to a system, refer to the
Circuit Identification Code Chart. This chart shows
the main circuits only and does not show the second-
ary codes that may apply to some models.

DESCRIPTION - SECTION IDENTIFICATION AND
INFORMATION
The wiring diagrams are grouped into individual
sections. If a component is most likely found in a par-
ticular group, it will be shown complete (all wires,
connectors, and pins) within that group. For exam-
ple, the Auto Shutdown Relay is most likely to be
found in Group 30, so it is shown there complete. It
can, however, be shown partially in another group if
it contains some associated wiring.
Splice diagrams in Section 8W-70 show the entire
splice and provide references to other sections the
splices serves. Section 8W-70 only contains splice dia-
grams that are not shown in their entirety some-
where else in the wiring diagrams.
Section 8W-80 shows each connector and the cir-
cuits involved with that connector. The connectors
are identified using the name/number on the dia-
gram pages.

ADJUSTMENT - DIFFERENTIAL SIDE GEAR
END PLAY
Measure side gear end play: Insert feeler gauges
180É apart between differential side gear and thrust
washer as shown in (Fig. 124). Measurement taken
here applies to both sides. Side gear end play should
be between 0.025-0.152 mm (0.001-0.006 in.). If clear-ance is greater than 0.152 mm (0.006 in.), install a
thicker thrust washer (both sides). If clearance is less
than 0.025 mm (0.001), install a thinner thrust
washer (both sides). Refer to (Fig. 125) for available
side gear shim thicknesses.

circuit.
TEST RESULT INDICATIONS
(1) If proper line pressure is found in any one test,
the pump and pressure regulator are working prop-
erly.
(2) Low pressure in all positions indicates a defec-
tive pump, a clogged filter, or a stuck pressure regu-
lator valve.

lator valve. (3) Clutch circuit leaks are indicated if pressures
do not fall within the specified pressure range. (4) If the overdrive clutch pressure is greater than
5 psi in Step 4 of Test Three, a worn reaction shaft
seal ring or a defective solenoid assembly is indi-
cated. (5) If the underdrive clutch pressure is greater

ented 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 com-
pressor. 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 fail-
ure and severe damage to the compressor front
cover.
(3) Install and securely 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. 6).
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. 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. 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.
NOTE: The shims may compress after tightening
the shaft bolt. Check the air gap in four or more
places to verify the air gap is still correct. Spin the
pulley before performing a final check of the air
gap.
(8) With the clutch plate assembly tight against
the shim(s), measure the air gap between the clutch
plate and the pulley face with feeler gauges. The air
gap should be between 0.35 - 0.60 mm (0.014 - 0.024
in.). If the proper air gap is not obtained, add or sub-
tract shims as needed until the desired air gap is
obtained.
(9) Install the compressor shaft bolt. Tighten the
bolt to 17.5 N´m (155 in. lbs.).
(10) On models with the 2.4L and 2.5L engines,
loosely install the four bolts that secure the compres-
sor to the mounting bracket on the engine (2.4L), or
the cylinder block (2.5L). Tighten the bolts to 28 N´m
(21 ft. lbs.).
(11) On models with the 3.3L and 3.8L engines,
loosely install the two bolts and two nuts that secure
the compressor to the engine. Tighten each of the fas-
teners to 54 N´m (40 ft. lbs.) using the following
sequence:
²The upper nut at the front of the compressor.
²The lower nut at the front of the compressor.
²The upper bolt at the rear of the compressor.
²The lower bolt at the rear of the compressor.
(12) On models with the 3.3L and 3.8L engines,
engage the retainer on the engine wire harness com-
pressor 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
