SH#T I' never heard of that before!

is the car hard to steer?

you should empty the whole lot out and put new fluid in
you will have to introduce air to the system,

take the return line off and position it so it emties into a container
start the motor and let it idle and swich off when empty (dry running will
damage the pump)
reconnect the return line and add new fluid
evacuate system air by turning steering wheel from side to side (the steering
will be stiff initially or may feel "lumpy" or intermittent but should come
good)
once the steering feels normal, you're set!

of couse that there will be a small amount of old fluid but this is nothing
to worry about,

If this happens again, theres somethin' seriously gone wrong
this is where experts should be called apon.

good luck mate!

Thanks for all of the great input. Turns out this time around I went ahead and used the "turkey baster" approach however with some modification. I started by running the car, then turning it off and removing just enough fluid (about half of the reseviour) so not to introduce air into the system. Did this a number of times. Fluid improved. Then I decided just to let it run and idle -- as I changed more fluid out -- again just about half of the tank -- did this several times -- continued to improve. Then I decided just to drive the car to a lot where I could turn it lock to lock then change 1/2 fluid. Then drive again change half fluid. Repeated this several times. In the end I matched colour from res fluid to new fluid and the match is almost identical (started very very grey). Overall, I went thru a total of about 10 quarts -- it took a total of four+ hours. Did not have an assistant thru this process, did not introduce much air (if any) and did not jack the car off the ground. It appears that the fluid is remaining clean and the steering feels positive and solid.

Next time around, I'll probably apply the more traditional technique with assistant and flush by removing hose. I see where this would be quite a bit faster.

Thanks again for all of the input!

Mine was black. Tried changing the whole resevoir using the turkey baster a couple of times, but soon it looked just as bad as before. Used the complete flush method in the FAQ and it has stayed looking good since.

It is still hard to steer when cold, though.

Use ATF for replacement fluid. Synthetic ATF if you want the the very best possible.

See the 700/900 FAQ under features button above for tips.

The method in the FAQ of pulling the return line and cranking the engine (disconnect ignition first) worked pretty good for me. Others will probably have more creative tips.
