Chrysler PT Cruiser. Manual — part 457
DISASSEMBLY
(1) Remove the three hex drive bolts and washers
that attach the power steering pump to the water
pump (Fig. 27).
(2) Use the following steps to access the water
pump impeller hex.
(a) Place a
1
⁄
4
inch drive 10 mm socket in
through the coolant inlet tube, then back it into
the heater hose fitting area as shown (Fig. 30).
Backing the socket into the heater hose fitting
makes it easier to perform the following step.
(b) Holding the socket in this position, insert a
1
⁄
4
inch drive extension (6 inches in length or
longer) in through the heater hose fitting into the
rear of the 10 mm socket.
(c) Push the socket with the extension into the
pump placing the socket on the hex built into the
center of the water pump impeller.
(3) While holding the power steering pump shaft
from turning using a hex wrench in the pulley end of
the shaft, loosen the impeller by rotating the
1
⁄
4
inch
drive extension counterclockwise using a ratchet. The
water pump will rise off of the power steering pump
as the impeller is rotated.
(4) Once
the
threads
have
been
disengaged,
remove the entire water pump assembly from the
power steering pump. If the water pump will be
used again, the 10 mm socket and extension can
be left inside the water pump until reassembly
is completed.
(5) If the water pump inlet cover needs to be
removed, remove the seven fasteners around the
perimeter of the pump and remove the cover. Discard
the housing O-ring type seal.
(6) If the power steering pump pulley needs to be
removed, (Refer to 19 - STEERING/PUMP - DISAS-
SEMBLY).
NOTE: For reassembly, (Refer to 7 - COOLING/EN-
GINE/WATER PUMP - ASSEMBLY).

WATER PUMP/POWER STEERING PUMP ASSEMBLY (Continued)
ASSEMBLY
(1) If the water pump inlet cover needs to be
installed on the water pump:
(a) First apply Mopar
t Dielectric Grease or
equivalent to a NEW water pump O-ring seal.
(b) Place the O-ring seal in the housing groove
where the cover contacts the housing.
(c) Install the seven fasteners around the perim-
eter of the pump. Tighten them to 12 N·m (105 in.
lbs.) torque.
(2) If a pulley needs to be installed on the power
steering pump, (Refer to 19 - STEERING/PUMP -
ASSEMBLY).
(3) Place the water pump assembly onto the power
steering pump shaft.
(4) Rotate the water pump so the water pump out-
let is near the water pump upper mounting holes
(hole with dowel guide). Arrange the three pump fas-
tener holes so they line up.
(5) If the water pump impeller hex has not been
accessed with a socket, use the following steps to
access the water pump impeller hex.
(a) Place a
1
⁄
4
inch drive 10 mm socket in
through the coolant inlet tube, then back it into
the heater hose fitting area as shown (Fig. 30).
(b) Holding the socket in this position, insert a
1
⁄
4
inch drive extension (6 inches in length or
longer) in through the heater hose fitting into the
rear of the 10 mm socket.
(c) Push the socket with the extension into the
pump placing the socket on the hex built into the
center of the water pump impeller.
(6) While holding the power steering pump shaft
from turning using a hex wrench in the pulley end of
the shaft, tighten the water pump impeller rotating
the
1
⁄
4
inch drive extension clockwise using a ratchet.
This will draw the water pump in toward the power
steering pump. Tighten the impeller to 26 N·m (19 ft.
lbs.) torque.
(7) Remove the 10 mm socket,
1
⁄
4
inch extension
and ratchet from the water pump. Remove the hex
wrench.
(8) Align the three pump fastener holes and install
the three hex drive bolts with washers (Fig. 27).
Tighten the bolts to 26 N·m (19 ft. lbs.) torque.
(9) Install assembly on the vehicle. (Refer to 7 -
COOLING/ENGINE/WATER PUMP - INSTALLA-
TION)
INSTALLATION
NOTE: Water pump and power steering pump must
be attached to one another before installation in
vehicle. For proper procedure, (Refer to 7 - COOL-
ING/ENGINE/WATER PUMP - ASSEMBLY).
(1) Install
water
pump/power
steering
pump
assembly into engine compartment in reverse of how
it was removed.
(2) Install all four power steering pump mounting
bolts (Fig. 29). Tighten bolts to 28 N·m (21 ft. lbs.)
torque.
(3) Install coolant outlet connector hose at water
pump outlet. Install clamp.

WATER PUMP/POWER STEERING PUMP ASSEMBLY (Continued)
(4) Using a lint free towel, wipe clean the open
power steering hose end and the power steering
pump port. Replace the used O-ring with new. Lubri-
cate the O-ring with power steering fluid.
(5) Attach the power steering fluid pressure hose
to the pump outlet port (Fig. 28). Do not tighten the
tube nut at this time.
(6) Install the bolt fastening the power steering
pressure hose to the reservoir bracket (Fig. 28).
(7) Tighten power steering pressure hose tube nut
