POWER STEERING PRESSURE
SWITCH
DESCRIPTION
A pressure sensing switch (Fig. 6) is included in
the power steering system (mounted on the high-
pressure line). This switch will be used only on vehi-
cles equipped with a 4.7L V–8 engine and power
steering.
OPERATION
The power steering pressure switch provides an
input to the Powertrain Control Module (PCM). This
input is provided during periods of high pump load
and low engine rpm; such as during parking maneu-
vers. The PCM will then increase the idle speed
through the Idle Air Control (IAC) motor. This is
done to prevent the engine from stalling under the
increased load.
When steering pump pressure exceeds 3275 kPa
6
690 kPa (475 psi
6 100 psi), the normally closed
switch will open and the PCM will increase the
engine idle speed. This will prevent the engine from
stalling.
When pump pressure drops to approximately 1379
kPa (200 psi), the switch circuit will re-close and
engine idle speed will return to its previous setting.

REMOVAL
This switch is used only with 4.7L V-8 engine.
The power steering pressure switch is installed in
the power steering high-pressure hose (Fig. 6).
(1) Disconnect electrical connector from power
steering pressure switch.
(2) Place a small container or shop towel beneath
switch to collect any excess fluid.
(3) Remove switch. Use back-up wrench on power
steering line to prevent line bending.
INSTALLATION
This switch is used only with 4.7L V-8 engine.
(1) Install power steering switch into power steer-
ing line.
(2) Tighten to 14–22 N·m (124–195 in. lbs.) torque.
(3) Connect electrical connector to switch.
(4) Check power steering fluid and add as neces-
sary.
(5) Start engine and again check power steering
fluid. Add fluid if necessary.
PULLEY
REMOVAL
CAUTION: On vehicles equipped with the 4.7L, Do
not reuse the old power steering pump pulley it is
not intended for reuse. A new pulley must be
installed if removed.
(1) Remove pump assembly, (Refer to 19 - STEER-
ING/PUMP 4.7L - REMOVAL) OR (Refer to 19 -
STEERING/PUMP 5.2 L & 5.9L - REMOVAL).
(2) Remove pulley from pump with Puller C-4333
(Fig. 7).
INSTALLATION
CAUTION: On vehicles equipped with the 4.7L, Do
not reuse the old power steering pump pulley it is
not intended for reuse. A new pulley must be
installed if removed.
(1) Replace pulley if bent, cracked, or loose.
(2) Install pulley on pump with Installer C-4063-B
(Fig. 8) flush with the end of the shaft. Ensure the
tool and pulley remain aligned with the pump shaft.
(3) Install pump assembly, (Refer to 19 - STEER-
ING/PUMP 4.7L - INSTALLATION) OR (Refer to 19
- STEERING/PUMP 5.2L & 5.9L - INSTALLATION).
(4) With Serpentine Belts; Run engine until warm
(5 min.) and note any belt chirp. If chirp exists, move
pulley outward approximately 0.5 mm (0.020 in.). If
noise increases, press on 1.0 mm (0.040 in.). Be
careful that pulley does not contact mounting
bolts.

STEERING GEAR HOUSING
PLUG
REMOVAL
(1) Rotate retaining ring until one end is under
the hole in the housing. Unseat and force ring from
groove (Fig. 1).
(2) Rotate stub shaft slowly COUNTER-CLOCK-
WISE to remove end plug out from housing.
CAUTION: Do not turn stub shaft any further than
necessary. The recirculating balls will drop out of
the rack piston circuit and fall inside the rack pis-
ton chamber.
(3) Remove O-ring seal (Fig. 2).
