Power Steering System Flushing

Power Steering System Flushing

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
CAUTION: Be prepared to collect escaping fluids.
NOTE:
Note the orientation of the clip.
Detach the power steering fluid reservoir.
- Detach but do not remove the power steering fluid reservoir.
- Release the power steering fluid return hose from the power steering fluid reservoir.
- If a quick release coupling is fitted to the power steering return hose, release the power steering fluid return hose from the coupling by removing the clip.




4
CAUTION: 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
CAUTION: Be prepared to collect escaping fluids.
NOTE:
Make sure the extended pipe is not kinked or twisted and is correctly secured with hose clips.
Attach a suitable pipe to the power steering return hose to allow the fluid to drain.




6
NOTE:
The suitable funnel should have the a capacity of 4 liters and O-ring seal
NOTE:
The suitable funnel must be tightly sealed to the power steering fluid reservoir to avoid fluid leakage.
Install a suitable funnel onto the power steering fluid reservoir.

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
CAUTION: 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.
CAUTION: Be prepared to collect escaping fluids.
Using the suitable funnel, top up the power steering system with the specified fluid. Make sure the fluid level is maintained at two thirds full in the funnel.




9
CAUTION: Be prepared to collect escaping fluids.
CAUTION: Do not allow the power steering fluid level in the power steering fluid reservoir to fall below the minimum power steering fluid level. Failure to follow this instruction may result in damage to the power steering system.
CAUTION: Make sure the engine is switched off as soon as the full 4 liters of power steering fluid has entered the power steering fluid reservoir.
Flush the power steering system.
- Start the engine
- With assistance turn the steering slowly lock to lock 3 times at approximately 1 revolution every 5 seconds.
- Continue to flush the power steering system until 4 liters of power steering fluid has been added to the power steering reservoir. This should take approximately 30 seconds.





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





11
CAUTION: Be prepared to collect escaping fluids.
Remove the suitable pipe to the power steering return hose.

12
CAUTION: Be prepared to collect escaping fluids.
NOTE:
Note the orientation of the clip.
If a quick release coupling is fitted to the power steering return hose, connect the power steering fluid return hose to the coupling by installing the clip.

13 Install a new power steering fluid reservoir. For additional information, refer to Power Steering Fluid Reservoir - 4.2L/3.0L/2.7L Diesel
