Hi This is from a fellow Zoner,I just copied and pasted.


You will need:
• Some latex gloves (the old fluid is very nasty stuff)
• Large syringe or something to remove the old fluid from the reservoir.
• A small bucket and old oil can for the waste fluid.
• Plenty of rags or cloth for spillages.
• Some white spirit for cleaning.
• Small paintbrush (1/2â€a).
• 2 new jubilee clips to replace the pipe clips on the hoses to the reservoir.
• New fluid (Dexron II ATF) (not sure about the quantity - 2 litres?)
• An assistant for the flush & bleed phase.

1. Using the large syringe, empty the reservoir of the old fluid.

2. Put some rags under the reservoir to catch spillage & protect the paintwork.

3. Remove the 3 bolts for the reservoir clamp, cut off the old hose clips and, after making a note of which pipe goes where, remove the pipes from the reservoir.

4. Remove the fluid reservoir and clean it thoroughly with the white spirit and paint brush.
Pay special attention to the mesh screen on the fluid return port of the reservoir (this screen, when blocked, can be the source of any noises).

5. Once cleaned & dried off as much as possible, temporarily plug the fluid return port of the reservoir (make sure that the plug can be removed quickly though) and refit the fluid feed pipe to the reservoir using one of the new jubilee clips.

6. Route the fluid return pipe from the rack into the bucket or old oil can to catch the fluid that will be lost during the flush.

7. Fill the reservoir with fresh fluid, get your assistant to start the engine and slowly turn the steering wheel from full lock to lock & back again several times. As the fluid is sucked out of the reservoir by the pump, keep adding fresh fluid until clean fluid starts dumping in to the waste bucket.

8. Turn off the engine. Make sure the second jubilee clip is slipped over the fluid return pipe then quickly remove the temporary plug and refit the return pipe to the reservoir. Tighten the jubilee clip.

9. Top up the reservoir with fresh fluid to the Max mark on the cap dipstick, get your assistant to start the engine again and slowly turn the steering wheel from full lock to lock & back again several times, in order to bleed the system. Re-check & top-up the fluid level with the engine running until you are certain that no more air bubbles are coming up into the reservoir. Check the pipes for leaks and, if OK, refit the clamp bolts.

10. Remove the rags from the engine bay (it's embarrassing when they start smouldering!!!) and take the car for a test drive but do keep in mind that you have been playing with the steering system, so be carefully.

Did mine this afternoon.
