Principles of Operation
The steering wheel rotational movement is
transferred to the steering gear through the steering
column shaft. The steering gear converts this
rotational movement, through the action of the rack
and pinion gear into lateral movement. This
movement in turn is transferred to the wheel
knuckles through the tie-rods and tie-rod ends.
Hydraulic fluid under pressure is supplied to the
steering gear by the power steering pump. As the
steering wheel is rotated, the hydraulic fluid is
allowed to pass through the steering gear valve to
one side of a double acting piston, dependent on
which direction the steering wheel is rotated. The
fluid moves the piston, which forms part of the
steering gear, giving power assistance to the effort
required to rotate the steering wheel.
Vehicles with petrol engines, due to the extra load
on the engine imposed by the power steering
pump, have a power steering pressure (PSP)
switch. The switch, which is normally closed, sends a signal
to the powertrain control module (PCM)
during low speed parking manoeuvres. The PCM
responds by maintaining the engine idle speed.
lnspection and Verification
1. Verify the customer concern.
2. Visually inspect for obvious signs of mechanical
or electrical damage.

air bag module at the top of the steering column.
6. Start the engine and turn the steering wheel
from lock to lock several times until the power
steering fluid has reached normal operating
temperature.
7. Using a suitable torque wrench and socket,
check the steering wheel turning effort.

1. N0TE:When filling the power steering fluid
reservoir, make sure that the power steering
fluid is clean and not agitated prior to use.
The power steering fluid should be poured
slowly into the reservoir to minimize the
possibility of aeration. The power steering
fluid level should be checked with the power
steering fluid cold.

2. Raise and support the vehicle making sure
that the road wheels are just clear of the
floor. For additional information, refer to:

3.
N0TE:Do not start the engine at this stage.
N0TE:Make sure that the power steering fluid in
the power steering fluid reservoir does not fall
below the MIN mark,
as air could enter the system.
Slowly turn the steering wheel from lock to
lock and add power steering fluid until the
power steering fluid in the power steering

in the power steering fluid reservoir stops
dropping.
5. Switch the engine OFF and using the special
tools, create a vacuum of
62cm-Hg - 75cm-Hg
for 30 seconds.
6. Observe the vacuum gauge reading.
If the vacuum decreases by more than
5cm-Hg
in 5 minutes, the system should be
checked for leaks.

GENERAL PROCEDURES
Start the engine and slowly turn the steering
wheel from lock to lock and add power
steering fluid until the power steering fluid
in the power steering fluid reservoir does
not drop.
8. Switch OFF the engine and examine the
power steering hose connections, steering
gear boots, power steering valve body and
power steering pump for external leaks.
9. Check the power steering fluid level. Fill the
power steering fluid reservoir to the MAX
mark with the appropriate power steering
fluid.

N0TE:When bleeding the power steering
system the vacuum will decrease. Using
the special tools, maintain a sufficient
vacuum of
38cm-Hg. If the vacuum
decreases by more than
5cm-Hg in 5
minutes, the system should be checked for
leaks.
Using the special tools, bleed the power
steering system in the following sequence.
1. Start the engine and slowly turn the steering
wheel from lock to lock once; then turn the
steering wheel to the right, just off the stop.
2. Switch OFF the engine.
3. Using the special tools, create a vacuum of
38cm-Hg. Maintain the vacuum until the air
is evacuated from the system (minimum of
five minutes).
4. Release the vacuum.
5. Repeat the power steering bleeding
procedure, turning the steering wheel to the
left, just off the stop.
11. Remove the special tools. Fill the power
steering fluid reservoir to the MAX mark

with the appropriate power steering fluid (
as necessary.
For additional information, refer to:

12. Start the engine, turn the steering wheel
from lock to lock. If excessive noise is
apparent, repeat the power steering
bleeding procedure.
13. Lower the vehicle.
14.
If the noise level is still unacceptable, leave
the vehicle standing overnight then repeat
the power steering system bleeding
