2004 CHRYSLER VOYAGER engine

NOTE: * Steering shudder can be expected in new
vehicles and vehicles with recent steering system
repairs. Shudder should dissipate after the vehicle
has been driven several weeks.
NOTE: ** To evaluate this condition, it may be nec-
essary to disconnect the coupling at the base of the
steering column. Turn the steering wheel and feel or
listen for internal rubbing in steering column. To
avoid damaging the column clockspring, note the
following. Before disconnecting coupling, place
tires in the straight-ahead position and center steer-
ing wheel. Once disconnected, DO NOT rotate
steering wheel more than one revolution in eitherdirection and place steering wheel in original loca-
tion before reconnecting coupling. If this position is
lost, the steering column clockspring must be
recentered following the procedure found within the
procedure for steering column installation in the
steering column section.
NOTE: *** Increased low speed or stationary steer-
ing effort can be expected if the steering fluid is at
a high temperature. High fluid temperature usually
results from high engine rpm due to trailer towing,
ascending grades, or racing the engine for pro-
longed periods of time.

STEERING (Continued)

OPERATION
Turning of the steering wheel is converted into lin-
ear (side-to-side) travel through the meshing of the
helical pinion teeth with the rack teeth in the steer-
ing gear. This travel pushes and pulls the tie rods to
change the direction of the vehicle's front wheels.
Power assist steering provided by the power steer-
ing pump is controlled by an open center, rotary type
control valve which directs oil from the pump to
either side of the integral rack piston upon demand.
Road feel is controlled by the diameter of a torsion
bar which initially steers the vehicle. As required
steering effort increases, as in a turn, the torsion bar
twists, causing relative rotary motion between the
rotary valve body and the valve spool. This move-
ment directs oil behind the integral rack piston
which, in turn, builds hydraulic pressure and assists
in the turning effort.
Manual steering control of the vehicle can be main-
tained if power steering assist is lost. However,
under this condition, steering effort is significantly
increased.
WARNING
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.
REMOVAL
REMOVAL - LHD GEAR
(1) Remove cap from power steering fluid reser-
voir.
(2) Using a siphon pump, remove as much fluid as
possible from the power steering fluid reservoir.Use
care not to damage the filter mesh below the
fluid surface.
CAUTION: Locking the steering column in the
straight-ahead position will prevent the clockspring
from being accidentally over-extended when the
steering column is disconnected from the interme-
diate steering coupler.
(3) Position the steering wheel in the STRAIGHT-
AHEAD position. Lock the steering wheel in place
using a steering wheel holding tool.
(4) With the vehicle on the ground, disconnect the
steering column shaft coupler from the steering gear
intermediate coupler (Fig. 2).

PUMP
DESCRIPTION
DESCRIPTION - PUMP (2.4L/3.3L/3.8L
ENGINE)
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
on the back side of the engine on all engine applica-
tions. The pumps are different depending on the
engine option. The pump for the 2.4L engine is madeout of cast iron and steel (Fig. 1). The pump used on
the 3.3L/3.8L engine is made of aluminum (Fig. 2).
The pump for the 3.3L/3.8L engine does not have a
return fitting as the pump for the 2.4L engine does.
The power steering return hose on the 3.3L/3.8L
engine goes to the reservoir instead of the 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. 13).
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.
19 - 36 PUMPRS

OPERATION
The power steering pump is a constant displace-
ment vane type pump. The 2.4L pump has an inte-
gral fluid reservoir and there is a secondary remote
non-flow reservoir which acts only as a fluid fill and
check point. The 3.3L/3.8L pump houses very little
fluid and is therefore supplied by a remote flow
through reservoir.
WARNING
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
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
WARNING: FLUID LEVEL SHOULD BE CHECKED
AND ADJUSTED WITH ENGINE OFF TO PREVENT
INJURY FROM MOVING ENGINE COMPONENTS.
CAUTION: Use only MoparTAutomatic Transmis-
sion Fluid (MS-9602) in power steering system. Use
of other MoparTpower steering fluids (MS5931 and
MS9933) should be avoided to ensure peak perfor-
mance of the power steering system under all oper-
ating conditions. 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
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
steering fluid as possible from the power steering
fluid reservoir.
(4) Raise the vehicle on jack stands or centered on
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.(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.
