PUMP
DESCRIPTION
Hydraulic pressure for the power steering system
is provided by a belt driven power steering pump
(Fig. 1). The pump shaft has a pressed-on high
strength plastic drive pulley that is belt driven by
the crankshaft pulley. The integral reservoir used on
the 3.7L only is attached to the pump body with
spring clips (Fig. 1). The 2.4L uses a remote fluid res-
ervoir (Fig. 2). The power steering pump is connected
to the steering gear by the pressure and return
hoses.
OPERATION
The power steering pump is a constant flow rate
and displacement, vane-type pump. The pump inter-
nal parts operate submerged in fluid. The flow con-
trol orifice is part of the high pressure line fitting.
The pressure relief valve inside the flow control valve
limits the pump pressure.Fig. 1 POWER STEERING PUMP ASSEMBLY

NOTE: Power steering pumps have different pres-

pumps.
STANDARD PROCEDURE - POWER STEERING
PUMP - INITIAL OPERATION
WARNING: THE FLUID LEVEL SHOULD BE
CHECKED WITH ENGINE OFF TO PREVENT INJURY
FROM MOVING COMPONENTS.
CAUTION: Use MOPAR Power Steering Fluid or
equivalent. Do not use automatic transmission fluid
and do not overfill.
Wipe filler cap clean, then check the fluid level.
The dipstick should indicateCOLDwhen the fluid is
at normal ambient temperature.
(1) Fill the pump fluid reservoir to the proper level
and let the fluid settle for at least two minutes.
(2) Raise the front wheels off the ground.
(3) Slowly turn the steering wheel right and left,
lightly contacting the wheel stops at least 20 times.
(4) Check the fluid level add if necessary.
(5) Lower the vehicle, start the engine and turn
the steering wheel slowly from lock to lock.
(6) Stop the engine and check the fluid level and
refill as required.
CAUTION: Do not run a vehicle with foamy fluid for
an extended period. This may cause pump damage.
(7) If the fluid is extremely foamy or milky look-
ing, allow the vehicle to stand a few minutes and
repeat the procedure.
(8) Add fluid if necessary. Repeat the above proce-
dure until the fluid level remains constant after run-
ning the engine.
REMOVAL

FLUID COOLER
DESCRIPTION
The power steering fluid cooler is located at the
front of the vehicle. It is mounted to the radiator
lower support just forward of the air-conditioning
condenser and just rearward of the front fascia. The
cooler is positioned so it is in the air flow through the
front fascia of the vehicle (Fig. 5)
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 fin/tubes 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 series with the power steering
fluid return line, between the steering gear and the
power steering fluid reservoir. This lowers the tem-
perature of the power steering fluid prior to it enter-
ing the power steering fluid reservoir where it is
resupplied to the power steering pump.
REMOVAL
(1) Remove the return line at the gear.
(2) Remove the return line at the reservoir.
(3) Remove the grille (Refer to 23 - BODY/EXTE-
RIOR/GRILLE - REMOVAL).
(4) Remove the two cooler mounting bolts. (Fig. 5)
(5) Remove the cooler from the vehicle.
INSTALLATION
(1) Install the cooler to the vehicle.
(2) Install the two cooler mounting bolts. (Fig. 5).
(3) Install the grille (Refer to 23 - BODY/EXTERI-
OR/GRILLE - INSTALLATION).
(4) Install the return line at the reservoir.
(5) Install the return line at the gear.
(6) Refill the power steering fluid and check for
leaks (Refer to 19 - STEERING/PUMP - STANDARD
PROCEDURE).
