2. Note that air in the fluid can temporarily result in PAS pump
noise, but this will not cause damage. The time allowances
mentioned in the above procedures are to reduce the possibility
of a customer collecting a vehicle while still subject to
excessive pump noise.

e
ral Procedures
• NOTE: If heavy steering or contamination within the power steering system is found, it is necessary to carry out the
system flush procedure as detailed below. If any components have been replaced in the power steering system the
procedure below must be carried out in full.
• NOTE: Some variation in the illustrations may occur, but the essential information is always correct.
1. Remove the power steering fluid reservoir cap.
2. Using a suitable syringe, remove the power steering fluid from
the power steering fluid reservoir.

3. CAUTIO
N: Be prepared to
collect escaping fluids.
• NOTE: Note the orientation of the clip. Detach the power steeri ng fluid reservoir.
De
tach but do not remove the power steering fluid
reservoir.
Re lea
se the power steering fluid return hose from the
power steering fluid reservoir.
If a qui
ck release coupling is fitted to the power
steering return ho se, release the powe r steering fluid
return hose from the coupling by removing the clip.

4. CAUTIO
N: Be prepared to
collect escaping fluids.
• NOTE: Make sure that all openings are sealed. Use new
blanking caps.
Using a suitable blanking cap, cap the power steering
reservoir return pipe.
5. CAUTIO
N: Be prepared to
collect escaping fluids.
• NOTE: Make sure the extended pipe is not kinked or twisted
and is correctly secure d with hose clips.
Attach a suitable pipe to the power steering return hose to
allow the fluid to drain.

6. NO
TE: The suitable funnel should have the a capacity of 4
litres and O-ring seal
• NOTE: The suitable funnel must be tightly sealed to the
power steering fluid reservoi r to avoid fluid leakage.
Install a suitable funnel onto the power steering fluid
reservoir.
7. WARNING: Do not work on or under a vehicle supported
only by a jack. Always support the vehicle on safety stands.
Raise and support the vehicle with the wheels just clear of the
ground.
8. CAUTI
ONS:
Steps 8 and 9 must be carried out within 2 - 3 seconds of
each other. Failure to follow this instruction may result in damage
to the power steering system.
Be prepared to collect escaping fluids.
Using the suitable funnel, top up the power steering system
with the specified fluid. Make su re the fluid level is maintained
at two thirds full in the funnel.
9. CAUTI
ONS:
Be prepared to collect escaping fluids.

Do not al
low the power steering fluid level in the power
steering fluid reservoir to fall below the minimum power
steering fluid level. Fa ilure to follow this instruction may result
in damage to the po wer steering system.
Make sure the engine is swit ched off as soon as the full
4 litres of power steering flui d has entered the power steering
fluid reservoir.
Flush the power steering system.
St art
the engine
W
it
h assistance turn the stee
ring slowly lock to lock 3
times at approximately 1 revo lution every 5 seconds.
Continue
to flush the power steering system until 4
litres of power steering fl uid has been added to the
power steering reservoir. This should take
approximately 30 seconds.

10 . CAUTI
ON: Be prepared to
collect escaping fluids.
Remove the suitable funnel.

11 . CAUTI
ON: Be prepared to
collect escaping fluids.
Remove the suitable pipe to th e power steering return hose.
12. CAUTI
ON: Be prepared to
collect escaping fluids.

•
NOTE: Note the orientation of the clip.
If a quick release coupling is fitt ed to the power steering return
hose, connect the power steerin g fluid return hose to the
coupling by installing the clip.
13. Install a new power steering fl uid reservoir. For additional
information, refer to: (211-02) Power Steering Fluid Reservoi r - 4.2L/3.0L/2.7L Diesel

Description an
d Operation

Parts List
The power steering system is a rack and pinion design, with an engine-dri ve n pump providing the steering assistance. The
system features variable steering assistance with vehicle spee d, a variable ratio steering rack, and a hydraulic control valve
which has a torsion bar arrangement giving improved center feel to the steering.
Absolute cleanliness must be observed wh en replenishing the fluid or dismantling any part of the system. If any major
component is renewed a new fluid rese rvoir must be fitted. New fluid from a sealed container must be used.
