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.

PUMP
DESCRIPTION - PUMP (2.5L DIESEL)
Hydraulic pressure for the operation of the power
steering gear is provided by a belt driven power
steering pump. The power steering pump is mounted
front lower right corner of the engine (Fig. 2).
The pump has a supply fitting for fluid coming
from the reservoir and a pressure port for exiting
fluid that is headed for the steering gear.
REMOVAL - PUMP (2.5L DIESEL)
(1) Remove the negative (-) battery cable from the
battery and isolate cable.
(2) Remove the fill cap from the power steering
fluid reservoir.
(3) Using a siphon pump, remove as much power
steering fluid as possible from the fluid reservoir.
(4) Raise the vehicle. (Refer to LUBRICATION &
MAINTENANCE/HOISTING - STANDARD PROCE-
DURE)
(5) Remove the splash shields from below the
engine compartment.
(6) Remove the accessory drive belt from the power
steering pump pulley. (Refer to 7 - COOLING/AC-
CESSORY DRIVE/DRIVE BELTS - REMOVAL)
(7) Disconnect the fluid supply hose from the
pump (Fig. 1).
(8) Disconnect the pressure hose from the pump
(Fig. 1).
(9) Remove the bolt fastening the stamped bracket
on the rear of the pump to the cast bracket (Fig. 2).
(10) Remove the three front mounting bolts
through the pulley.
(11) Remove the pump from the cast bracket and
vehicle.
INSTALLATION - PUMP (2.5L DIESEL)
(1) Install the power steering pump on its cast
mounting bracket.
(2) Install the three front power steering pump
mounting bolts. Tighten the mounting bolts to a
torque of 54 N´m (40 ft. lbs.).(3) Install the rear mounting bolt fastening the
stamped bracket to the cast bracket (Fig. 2). Tighten
the mounting bolt to a torque of 54 N´m (40 ft. lbs.).
NOTE: Before installing power steering pressure
hose on power steering pump, inspect the O-ring
on the power steering pressure hose for damage
and replace if required.
(4) Install the power steering fluid pressure hose
fitting into the pressure port of the power steering
pump (Fig. 1). 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 supply hose on
the power steering pump supply fitting (Fig. 1).Be
sure hose clamp is properly reinstalled.
(6) Install the accessary drive belt (Refer to 7 -
COOLING/ACCESSORY DRIVE/DRIVE BELTS -
INSTALLATION).

(transmission fluid) this indicates that the Transmis-
sion differential carrier seal should be replaced. If
the fluid leaking is light brown (gear lube) this indi-
cates that the Power Transfer Unit input seal should
be replaced. For replacement of these seals refer to
Power Transfer Unit Service Procedures.
If fluid is leaking from weep hole B (Fig. 5) the
type of fluid leaking will determine which seal is
leaking. If the fluid leaking is red in color (transmis-
sion fluid) this indicates that the input shaft end seal
should be replaced. If the fluid leaking is light brown
(gear lube) this indicates that the half shaft innerseal and P.T.U. input shaft cover seal should be
replaced. For replacement of these seals refer to
Power Transfer Unit Service Procedures.
Before condemning any seal or gasket be sure that
the rear rocker arm cover on the engine is not the
cause of the oil leak. Oil leaking from the rocker arm
cover is easily mistaken for a leaking Power Transfer
Unit.
STANDARD PROCEDURE - FLUID LEVEL
INSPECTION
(1) Raise vehicle on hoist.
(2) Remove PTU inspection plug (Fig. 6).
(3) Fluid level should be within 3/16º from bottom
of inspection hole. Add Moparž Gear and Axle Lubri-
cant 80W-90 as necessary with suitable suction gun
(Fig. 7).
(4) Install inspection plug and torque to 20 N´m
(180 in. lbs.) torque.
(5) Lower vehicle.
STANDARD PROCEDURE - PTU FLUID CHANGE
NOTE: PTU Fluid should be changed upon servic-
ing the unit, or at the unit's regular scheduled inter-
val. (Refer to LUBRICATION & MAINTENANCE/
MAINTENANCE SCHEDULES - DESCRIPTION)
(1) Raise vehicle on hoist.
(2) Remove PTU inspection plug (Fig. 8).
