DIAGNOSTIC INFORMATION AND PROCEDURES
POWER STEERING SYSTEM
PRESSURE TEST
Tools Required
124 589 06 21 00 Power Steering Pump Testing Unit
Check the fluid pressure as follow to trouble is in the
pump or gear unit.
Test Procedure
1. Disconnect the pressure hose from the oil pump
and connect a pressure gauge between the oil
pump and pressure hose.
2. Bleed the system. Start the engine and turn the
steering wheel form lock several times until oil
temperature is up to 50 °C.
3. Run the engine at 1,000 rpm.
4. Close the gauge valve fully, and read pressure.
The pump pressure with the valve closed should
be between 7,355 kPa to 8,041 kPa (1,067 psi to
1,166 psi).
Notice: Do not keep the valve closed for more
than 10 seconds.
5. Remove the pressure gauge and connect the pres-
sure hose.
6. Do bleeding procedure.

LEAK TEST
General Procedure
Inspect the following :
The power steering fluid reservoir for overfill.
Fluid for aeration and overflow.
The hoses for loose connections.
The torsion bar, stub shaft and adjuster seals for
leaks.
The component sealing surfaces for damage.
Important: Verify the exact point of the leak. The point
from which the fluid is dripping is not necessarily the
point at which the system is leaking. When service is
required, clean the leak area upon disassembly,
replace the leaking seal, check the component sealing
surfaces for damage and reset the torque bolt to
specifications required.
External Leak Check
The purpose of this procedure is to pinpoint the location
of the leak. In some cases, the leak can be easily lo-
cated, but seepage-type leaks may be harder to find.
To locate seepage leaks, use the following method:
1. With the engine off, wipe dry the complete power
steering system.
2. Check the power steering fluid level in the pump’s
reservoir. Adjust the fluid level as necessary.
Refer to “Checking and Adding Fluid” in this
section.
Notice: Do not hold the steering wheel at a stop
for any length of time as this can damage the
power steering pump.
3. Start the engine. Turn the steering wheel counter-
clockwise and clockwise from stop to stop several
times.
4. Find the exact area of the leak and repair it.

BLEEDING THE POWER
STEERING SYSTEM
1. Disconnect the fuel line. Using a starter motor,
crank the engine and turn the steering wheel from
lock to start 5 or 6 times.
Notice: Do bleeding with engine cranking. If bleed
with idling, there can be a air contact with oil.
2. Connect the fuel feed line and start the engine at
idle speed.
3. Turn the steering wheel from lock to lock until there
is no more air in oil reservoir.
4. Connect the oil level is within specification.
5. By turning the steering wheel left to right, check
the oil level change.
Notice: If oil is not changes more than 5 mm, do
bleeding again. If oil level rises suddenly when
stopped engine, again.
MAINTENANCE
CHECKING AND ADDING FLUID
Notice: When adding fluid or making a complete fluid
change, always use DEXRON. - II power steering fluid.
Failure to use the proper fluid will cause hose and seal
damage and fluid leaks.
1. The power steering fluid level is indicated by marks
on a fluid level indicator on the fluid reservoir cap.
2. If the fluid is warmed up to 66 °C (150 °F), the fluid
level should be between the MAX and MIN marks.
Add fluid as needed.
3. If the fluid is cool, 21 °C (70 °F), the fluid level should
be at the MIN mark. Add fluid as needed.

6B-2 POWER STEERING PUMP
DESCRIPTION AND OPERATION
GENERAL DESCRIPTION
The power steering pump is a multivaned hydraulic
pump. The serpentine accessory drive belt on the en-
gine drives the power steering pump. The power steer-
ing pump provides the hydraulic pressure to the power
steering gear.
The power steering gear uses the hydraulic pressure
to assist in steering the vehicle.
When steering conditions exceed maximum pressure
requirements, such as when the wheels are turned
against the stops, the pressure built up in the steeringgear exerts pressure on the spring end of the flow
control valve. The high pressure lifts the relief valve
ball from its seat and allows oil to flow through a trigger
orifice located in the outlet fitting. This reduce pressure
on the spring end of the flow control valve which then
opens and allows the oil to return to the intake side of
the pump. This action limits maximum pressure output
of the pump to a safe level.
No repair procedures are to be done on the internal
components of the power steering pump. The only ser-
viceable components of the power steering pump are
the power steering pump pulley and the pump itself.

6C-2 POWER STEERING GEAR
POWER RACK AND PINION
The power steering rack and pinion system has a rotary
control valve that directs hydraulic fluid coming from
the hydraulic pump to one side or the other side of the
rack piston. The integral rack piston is attached to the
rack. The rack piston converts hydraulic pressure to a
linear force that moves the rack left or right. That force
is then transmitted through the tie rods to the steering
knuckles, which turn the wheels.
DESCRIPTION AND OPERATION
If power rack and pinion steering is not available, manu-
al rack and pinion control is used; however, with this
system, more steering effort is required. The movement
of the steering wheel is transferred to the pinion. The
rotary movement of the pinion is then transferred
through the pinion threads, which mesh with teeth on
the rack, thereby causing the rack to move in a linear
direction.
A vane-type of hydraulic pump provides hydraulic pres-
sure for both steering systems.
