STEERING
DESCRIPTION - POWER STEERING SYSTEM
This vehicle comes with power steering as stan-
dard equipment and it is the only steering system
available. The power steering system consists of
these major components:
²POWER STEERING PUMP
²POWER STEERING GEAR
²POWER STEERING FLUID RESERVOIR
²POWER STEERING FLUID SUPPLY HOSE
²POWER STEERING FLUID PRESSURE HOSE
²POWER STEERING FLUID RETURN HOSE
²POWER STEERING FLUID COOLER
For information on the first two components, refer
to their respective sections within this service man-
ual group. Information on all other components can
be found in POWER STEERING PUMP.
OPERATION - POWER STEERING SYSTEM
Turning of the steering wheel is converted into linear
(side-to-side) travel through the meshing of the helical
pinion teeth with the rack teeth within the steering
gear. The lateral travel pushes and pulls the tie rods to
change the direction of the vehicle's front wheels.
Power assist steering is provided by a belt driven
rotary type pump. It directs fluid through power
steering fluid hoses to the power steering gear where
it is used to assist the driver's 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.
DIAGNOSIS AND TESTING - POWER STEERING
SYSTEM FLOW AND PRESSURE TEST
ALL ENGINES
The following procedure is to be used to test the
operation of the power steering system on this vehi-
cle. This test will provide the flow rate of the power
steering pump along with the maximum relief pres-sure. This test is to be performed any time a power
steering system problem is present to determine if
the power steering pump or power steering gear is
not functioning properly. The following flow and pres-
sure test is performed using the Power Steering Ana-
lyzer Kit, Special Tool 6815 (Fig. 1), hoses, Special
Tools 6905 and 6959, and fittings from adapter kit,
Special Tool 6893.
Assemble hoses on Power Steering Analyzer, Spe-
cial Tool 6815, as shown. Install Pressure Hose, Spe-
cial Tool 6905 (in 6893 kit), in the inlet fitting on
Power Steering Analyzer. Install Pressure Hose, Spe-
cial Tool 6713 (in 6815 kit) on Pressure Hose, Special
Tool 6905. Install Pressure Hose, Special Tool 6959,
in the outlet fitting on Power Steering Analyzer.
Install the following adapters from Adapter Set,
Special Tool 6893 (Fig. 2), on the analyzer hose ends:
Install Adapter Fitting, Special Tool 6844, on Pres-
sure Hose, Special Tool 6713. Install Adapter Fitting,
Special Tool 6826, on Pressure Hose, Special Tool
6959.

CAUTION: To prevent personal injury, safety gog-
gles should be worn at all times when performing
any test procedures on the power steering pump or
power steering gear.
The following procedure is to be used to test the
operation of the power steering system on the vehi-
cle.
(1) Check belt tension and adjust as necessary.
(2) Disconnect the power steering fluid pressure
hose from the power steering pump (Fig. 3) (Fig. 4).
(3) Connect Adapter Fitting, Special Tool 6844,
attached to pressure hose from inlet (gauge end) ofPower Steering Analyzer to the pressure fitting on
the power steering pump.
(4) Connect vehicle power steering fluid pressure
hose to Adapter Fitting, Special Tool 6826, which
should be already installed in the outlet hose (valve
end) of Power Steering Analyzer.
(5) Completely open valve on Power Steering Ana-
lyzer.
(6) Start engine and let idle long enough to circu-
late power steering fluid through the analyzer and
hoses, until the air is out of the fluid. Shut off
engine.
(7) Check power steering fluid level and add fluid
as necessary. Start engine again and let idle.
(8) Gauge should read below 862 kPa (125 psi). If
above, inspect the hoses for restrictions and repair as
necessary. The initial pressure should be in the range
of 345-552 kPa (50-80 psi). The flow meter should
read between 1.3 and 1.9 GPM.
CAUTION: The following test procedure involves
testing maximum pump pressure output and flow
control valve operation. Do not leave valve closed
for more than five seconds as the pump could be
damaged.

NOTE: Power steering pump maximum relief pres-
sure is 9,653 to 10,342 kPa (1,400 to 1,500 psi.).
(9) Close analyzer valve fully three times and
record highest pressure indicated each time. All three
readings must be above specifications and within 345
kPa (50 psi) of each other.
²If power steering pump pressures are above
specifications, but not within 345 kPa (50 psi) of each
other, replace pump.
²If power steering pump pressures are within 345
kPa (50 psi) of each other, but are below specifica-
tions, replace pump.
CAUTION: Do not force the pump to operate against
the stops for more than 2 to 4 seconds at a time
because, pump damage will result.
(10) Completely open the valve on the Power
Steering Analyzer. Turn the steering wheel to theextreme left until the stop in the steering gear is
met, then turn the steering wheel to the right until
the right stop is met. Record the highest indicated
pressure at each position. Compare the recorded
readings to the specifications. If the highest output
pressures are not the same against either stop, the
steering gear is leaking internally and must be
replaced.
