STANDARD PROCEDURE - POWER STEERING
FLUID LEVEL CHECKING
WARNING: FLUID LEVEL SHOULD BE CHECKED
WITH THE ENGINE OFF TO PREVENT INJURY
FROM MOVING PARTS AND TO ENSURE ACCU-
RATE FLUID LEVEL READING.
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. 17).
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 only
MopartATF+4 Automatic Transmission Fluid
(MS-9602) in the power steering system.For
additional information on Automatic Transmission
Fluid, (Refer to LUBRICATION & MAINTENANCE/
FLUID TYPES - DESCRIPTION).
CAUTION: Use only MoparTATF+4 Automatic Trans-
mission Fluid (MS-9602). Use of other MoparT
power steering fluids (MS5931 and MS9933) should
be avoided to ensure peak performance of the
power steering system under all operating condi-
tions.

FLUID COOLER
DESCRIPTION
All models (except 2.5L Diesel) 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. 18).
There are two different size coolers depending on
model and options. There is a standard 6-inch and an
8-inch.
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.
The cooler used on this vehicle is referred to as a
fluid-to-air type cooler. This means that the air flow
across the tubes (and fines surrounding them) of the
cooler is used to extract the heat from the cooler
which it has absorbed from the power steering fluid
flowing through it. The cooler is placed in the power
steering fluid return line, between the steering gear
and the power steering fluid reservoir.
REMOVAL
(1) Using a siphon pump, remove as much fluid as
possible from the power steering fluid reservoir.
(2) Raise vehicle. (Refer to LUBRICATION &
MAINTENANCE/HOISTING - STANDARD PROCE-
DURE)
(3) Remove the hose clamps at the cooler and
remove the hoses from the cooler inlet and outlet
tubes.
(4) Remove the 2 bolts attaching the power steer-
ing cooler cradle crossmember reinforcement (Fig.
18). Remove the cooler.
INSTALLATION
(1) Install the power steering fluid cooler on the
cradle crossmember reinforcement (Fig. 18). Install
the mounting bolts and tighten to 11 N´m (100 in.
lbs.).
(2) Install power steering fluid hoses on the cooler.
Be sure hose clamps are installed on hose past
the upset bead on the power steering cooler
tubes.(3) Lower the vehicle to a point where front tires
are just off the ground.
(4) Perform Power Steering Pump Initial Opera-
tion procedure. (Refer to 19 - STEERING/PUMP -
