OPERATION
POWER STEERING PUMP — LHD
Removal
(1) Disconnect the negative battery cable.
(2) Remove the A/C line support bracket from the
rear of the rocker cover.
(3) Disconnect the A/C compressor electrical con-
nector.
(4) Remove the (2) engine mount upper sill plate
nuts (Fig. 1).
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 indicate
COLD
when 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) Start the engine and let run for a few seconds
then turn engine off.
(3) Add fluid if necessary. Repeat the above proce-
dure until the fluid level remains constant after run-
ning the engine.
(4) Raise the front wheels off the ground.
(5) Slowly turn the steering wheel right and left,
lightly contacting the wheel stops at least 20 times.
(6) Check the fluid level add if necessary.
(7) Lower the vehicle, start the engine and turn
the steering wheel slowly from lock to lock.
(8) Stop the engine and check the fluid level and
refill as required.
(9) If the fluid is extremely foamy or milky look-
ing, allow the vehicle to stand a few minutes and
repeat the procedure.

CAUTION: Do not run a vehicle with foamy fluid for
an extended period. This may cause pump damage.
(5) Make
sure
the
steering
wheel
is
in
the
unlocked position.
(6) Raise the vehicle on a hoist.

REMOVAL AND INSTALLATION (Continued)
CAUTION: Avoid turning the steering shaft while
disconnected from the steering gearbox. Damage to
steering column clockspring could occur.
(16) Support the A/C compressor with mechanics
wire before proceding to the next step.
(17) Remove
the
(4)
A/C
compressor
retaining
bolts.
(18) Remove the left engine mount throughbolt nut
only. Do not remove the bolt at this time.
(19) Position a jack stand and raise weight off left
engine mount.
(20) Remove the track bar support bracket retain-
ing bolts and remove bracket (Fig. 3).
(8) Remove the power steering fluid supply hose
from the pump and let the fluid drain.
(9) Loosen the (4) H-Block retaining bolts. Do not
remove the bolts at this time.
(10) Remove the accessory drive belt from the
power steering pump pulley. Refer to Group 7, Cool-
ing System for procedure.
(11) Remove the power steering pump pulley. Use
a hex socket to secure the pump shaft while remov-
ing the pulley nut with a box wrench (Fig. 2).

(21) Remove the lower engine mount bolt from the
sill plate (Fig. 3).
(22) Remove the (4) engine mount bracket bolts
from the engine block.
(23) Remove the engine mount throughbolt.
(24) Remove the engine mount and engine mount
bracket from the vehicle.
(25) Remove the (2) power steering pump retaining
nuts (Fig. 4).
(26) Remove the power steering pump from the
vehicle.
NOTE: Mark the position of the H-Block in relation
to the A/C Compressor so it may be reinstalled in
the same position.
(12) Remove the (2) bolts retaining the H-Block to
the power steering pump shaft coupler.
(13) Loosen the coupler pinch bolt and slide the
coupler towards the pump.
(14) Remove the power steering pump pressure
line from the steering gear. This is more accessible,
but will require you to install the pressure line on
the new pump prior to installation.
(15) Remove the remaining 2 bolts from the
H-Block and remove the H-Block from the compres-
sor.
