(10) Move the heat sleeve on the power steering
return hose to expose the hose connection at the
pump (Fig. 5). Remove the hose from the power
steering Pump. Allow the remaining power steering
fluid to drain from the power steering pump and res-
ervoir through the removed return hose.
(11) Remove the power steering fluid pressure line
from the power steering pump (Fig. 6). Drain excess
power steering fluid from tube.
(12) Remove the fasteners, then the accessory
drive splash shield.
(13) Remove the adjuster nut attaching rear of
power steering pump to the cast mounting bracket.
(Fig. 7)
(14) Remove the front adjuster nut and the lower
pivot bolt (Fig. 8) attaching power steering pump
bracket to cast bracket.
(15) Remove the drive belt from the power steering
pump pulley.
(16) Remove the power steering pump and the
front bracket from the cast bracket on the engine as
an assembly through the exhaust tunnel.
(17) Remove the 3 bolts attaching the front
bracket to the power steering pump and separate the
power steering pump from the front bracket.
(18) If transferal of the power steering pump pul-
ley is necessary, (Refer to 19 - STEERING/PUMP -
DISASSEMBLY).
REMOVAL - PUMP (3.3L/3.8L ENGINE)
(1) Remove the (-) negative battery cable from the
battery and isolate cable.
(2) Remove the wiper module (unit)(Refer to 8 -
ELECTRICAL/WIPERS/WASHERS/WIPER MOD-
ULE - REMOVAL).(3) Raise the vehicle.
(4) Remove the drive belt splash shield.

(4) Install the power steering fluid pressure line
into the pressure output fitting of the power steering
pump (Fig. 11). Tighten the pressure line to pump fit-
ting tube nut to a torque of 31 N´m (275 in. lbs.).
(5) Install the power steering fluid low-pressure
return hose on the power steering pump low pressure
fitting (Fig. 11).Be sure hose clamps are prop-
erly reinstalled.
(6) Raise the vehicle.
(7) Install the routing clip on the engine for the
pressure hose (Fig. 10).
(8) Tighten the pump thru-bolt (Fig. 9). Tighten to
54 N´m (40 ft. lbs.) torque.
(9) Install the serpentine drive belt (Refer to 7 -
COOLING/ACCESSORY DRIVE/DRIVE BELTS -
INSTALLATION).
(10) Install the drive belt splash shield.
(11) Lower the vehicle.
(12) Install the wiper module (unit)(Refer to 8 -
ELECTRICAL/WIPERS/WASHERS/WIPER MOD-
ULE - INSTALLATION).
(13) Connect the negative battery cable on the
negative battery post.
(14) Fill and bleed the power steering system
using the Power Steering Pump Initial Operation
Procedure (Refer to 19 - STEERING/PUMP - STAN-
DARD PROCEDURE).
(15) Inspect for leaks.
SPECIAL TOOLS
POWER STEERING PUMP
FLUID
STANDARD PROCEDURE - POWER STEERING
FLUID LEVEL CHECKING
WARNING: FLUID LEVEL SHOULD BE CHECKED
WITH THE ENGINE OFF TO PREVENT INJURY
FROM MOVING PARTS.
The fluid level can be read on the exterior of the
power steering fluid reservoir. The fluid level should
be within the ªFILL RANGEº when the fluid is at
normal ambient temperature, approximately 21ÉC to
27ÉC (70ÉF to 80ÉF) (Fig. 15).
Before removing the power steering filler cap, wipe
the reservoir filler cap free of dirt and debris. Do not
overfill the power steering system. Use onlyMopart
Power Steering Fluid (MS-5931)or quivalent.
FLUID COOLER
DESCRIPTION
All models of this vehicle are equipped with a
cooler for the power steering system fluid. The power
steering fluid cooler is located on the front suspen-
sion cradle crossmember reinforcement (Fig. 16).
There are two different size coolers offered depending
on options. There is a standard 6-inch and an 8-inch
for vehicles equipped with the heavy duty cooling
package.
OPERATION
The purpose of the power steering fluid cooler is to
keep the temperature of the power steering system
fluid from rising to a level that would affect the per-
formance of the power steering system.
