SERVICE WARNINGS AND CAUTIONS
WARNING: POWER STEERING FLUID, ENGINE
PARTS AND EXHAUST SYSTEM MAY BE
EXTREMELY HOT IF ENGINE HAS BEEN RUNNING.
DO NOT START ENGINE WITH ANY LOOSE OR DIS-
CONNECTED HOSES. DO NOT ALLOW HOSES TO
TOUCH HOT EXHAUST MANIFOLD OR CATALYST.
WARNING: FLUID LEVEL SHOULD BE CHECKED
WITH THE ENGINE OFF TO PREVENT PERSONAL
INJURY FROM MOVING PARTS.
CAUTION: When the system is open, cap all open
ends of the hoses, power steering pump fittings or
power steering gear ports to prevent entry of for-
eign material into the components.
STANDARD PROCEDURE - POWER STEERING
PUMP INITIAL OPERATION
CAUTION: The fluid level should be checked with
engine off to prevent injury from moving compo-
nents. Use only MoparTPower Steering Fluid (MS-
5931) or approved equivalent. Do not overfill.
Read the fluid level through the side of the power
steering fluid reservoir. The fluid level should indi-
cateªFILL RANGEºwhen the fluid is at a temper-
ature of approximately 21ÉC to 27ÉC (70ÉF to 80ÉF).
(1) Wipe the filler cap and area clean, then remove
the cap.
(2) Fill the fluid reservoir to the proper level and
let the fluid settle for at least two (2) minutes.
(3) Start the engine and let run for a few seconds,
then turn the engine off.
(4) Add fluid if necessary. Repeat the above steps
until the fluid level remains constant after running
the engine.
(5) Raise the front wheels off the ground.
(6) Start the engine.
(7) Slowly turn the steering wheel right and left,
lightly contacting the wheel stops.
(8) Add fluid if necessary.
(9) Lower the vehicle, then turn the steering wheel
slowly from lock-to-lock.
(10) Stop the engine. Check the fluid level and
refill as required.
(11) If the fluid is extremely foamy, allow the vehi-
cle to stabilize a few minutes, then repeat the above
procedure.
REMOVAL - PUMP (2.4L ENGINE)
(1) Remove the (-) negative battery cable from the
battery and isolate cable.
(2) Remove the cap from the power steering fluid
reservoir.
(3) Using a siphon pump, remove as much power

a frame contact type hoist. See Hoisting in Lubrica-
tion and Maintenance.
(5) Disconnect the oxygen sensor wiring harness
from the vehicle wiring harness at the rear engine
mount bracket.
NOTE: The exhaust system needs to be removed
from the engine to allow for an area to remove the
power steering pump from the vehicle.
(6) Remove the four bolts and flag nuts securing
the catalytic converter from the exhaust manifold
(Fig. 3).
(7) Disconnect all the exhaust system isolators/
hangers from the brackets on the exhaust system (2
at the mufflers and 1 at the resonator) (Fig. 4).
(8) Remove the exhaust system by moving it as far
rearward, then lowering the front below the cross-
member and out of the vehicle.
(9) Remove the power steering fluid supply hose
from the fitting on the power steering pump. Drain
off excess power steering fluid from hose.

DISASSEMBLY - PUMP (PULLEY)
The only serviceable part of the power steering
pump is the pulley. The procedure following is for
removal and installation of the pulley from the pump
once the pump is removed from the vehicle.(1) Remove the power steering pump from the
vehicle. Refer to Removal And Installation in this
section of the service manual.
(2) Remove the pulley from the shaft of the power
steering pump using Puller C-4333 or C-4068 (Fig.
12).
CAUTION: Do not hammer on power steering pump
pulley. This will damage the pulley and the power
steering pump.
(3) Replace pulley if it is found to be bent, cracked,
or loose.
ASSEMBLY - PUMP (PULLEY)
The only serviceable part of the power steering
pump is the pulley. The procedure following is for
removal and installation of the pulley from the pump
once the pump is removed from the vehicle.
(1) Install the pulley with Installer C-4063 (Fig.
13). Do not use the tool adapters.
(2) Ensure that the tool and the pulley remain
aligned with the pump shaft. Prevent the pulley from
being cocked on the shaft.
(3) Install the pulley until it is flush with the end
of the power steering pump shaft (Fig. 14).
(4) Install the power steering pump on the vehicle.
NOTE: Once the pump is installed on the vehicle,
run the engine until it's warm (5 min.) and note any
belt chirp. If chirp exists, move the pulley outward
approximately 0.5 mm (0.020 in.). If noise increases,
press the pulley on 1.0 mm (0.040 in.). Be careful
that the pulley does not contact the pump mounting
bolts.

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.
