(3) Using hand pressure, press firmly and evenly
on the washer pump until the inlet nipple is fully
seated in the rubber grommet seal in the washer res-
ervoir mounting hole (Fig. 10).
(4)
If the vehicle is so equipped, reconnect the
washer fluid level switch vent hose to the barbed vent
nipple at the top of the washer pump/motor housing.
(5) Reconnect the washer hose to the barbed outlet
nipple of the washer pump.
(6) Reconnect the vehicle wire harness connector
for the washer pump/motor unit to the motor connec-
tor receptacle.
(7) Refill the washer reservoir with the washer
fluid drained from the reservoir during the removal
procedure.
WASHER RESERVOIR
DESCRIPTION
The molded plastic washer fluid reservoir is located
in the right rear corner of the engine compartment
(Fig. 11). Two integral mounting posts, one on the bot-
tom and one at the rear of the reservoir, each are
engaged in rubber mounting grommets, one in the
dash panel and one in the top of the right front wheel
house. A single nut and washer secures an integral
mounting hole near the top of the reservoir to a stud
nut on the right inner fender shield. Also near the
upper inboard side of the reservoir are two integral
hose routing troughs, one for the standard washer sup-
ply hose and the second for the optional vent hose used
when the washer pump/motor is equipped with an
integral washer fluid level switch.
A molded blue plastic filler cap with an integral
retainer ring and tether strap snaps over the open
end of the filler neck, and hangs from the tether
when it is removed for inspecting or adjusting the
fluid level in the reservoir. There is a sump area near
the bottom inboard side of the reservoir with a dedi-
cated hole provided for the mounting of the washer/
pump motor unit and rubber grommet seal.
The washer reservoir cannot be repaired and, if
faulty or damaged, it must be replaced. The washer
reservoir, the mounting grommets, the grommet seal
for the washer pump/motor unit, and the filler cap
are each available for service replacement.
OPERATION
The washer fluid reservoir provides a secure,
on-vehicle storage location for a large reserve of
washer fluid for operation of the washer system. The
washer reservoir filler neck provides a clearly
marked and readily accessible point from which to
add washer fluid to the reservoir. The washer/pump
motor unit is located in a sump area near the bottom
of the reservoir to be certain that washer fluid will
be available to the pump as the fluid level in the res-
ervoir becomes depleted. The optional washer fluid
level switch is designed to provide adequate warning
to the vehicle operator that the washer fluid level is
low, before the washer system will no longer operate.
REMOVAL
(1)Disconnect and isolate the battery negative cable.
(2) Remove the upper turbocharger heat shield
and the upper air cleaner housing from the engine
compartment (Fig. 12).

nector receptacle.
(4) Disengage the vehicle wire harness from the
routing clip integral to the front of the washer reser-
voir (Fig. 13).

(8) Pull the washer reservoir inboard far enough to
disengage the reservoir from the stud nut.
(9) Tilt the washer reservoir forward far enough to
disengage the rear mounting post from the grommet
in the dash panel.
(10) Lift the washer reservoir upward far enough
to disengage the lower mounting post from the grom-
met in the top of the right front wheel house.
(11) Remove the washer reservoir from the engine
compartment.
INSTALLATION
(1) Position the washer reservoir into the engine
compartment.
(2) Engage the lower mounting post of the washer
reservoir into the grommet in the top of the right
front wheel house (Fig. 14).
(3) Engage the rear mounting post of the washer
reservoir into the grommet in the dash panel.(4) Position the washer reservoir mounting hole
over the stud nut on the right inner fender (Fig. 13).
(5) Install and tighten the nut and washer that
secures the top of the washer reservoir to the stud
nut on the right inner fender. Tighten the nut to 6
N´m (50 in. lbs.).
(6) Reconnect the washer supply hose to the
barbed outlet nipple of the washer pump/motor.
(7) Engage the washer supply hose into the rout-
ing trough integral to the top of the washer reservoir.
(8) Reconnect the vehicle wire harness connector
for the washer pump/motor unit to the motor connec-
tor receptacle.
(9) Engage the vehicle wire harness into the rout-
ing clip integral to the front of the washer reservoir.
(10) Reinstall the upper turbocharger heat shield
and the upper air cleaner housing into the engine
compartment (Fig. 12).

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.
