Total time approx 30 minutes... most of it letting it drain.
Total Cost about $5 bux
Locate the power steering lines going to the cooler

Remove the power steering cap to allow the fluid to drain freely

Remove both lines and let it drain.

Once it has stopped drainning, bump the starter a couple of times to move fluid along. Alot more fluid will come out doing this.
When it's done draining, replace both lines on the cooler
Brownish in color (normal according to the manual)

Refill with approx 1 quart of ATF-4 fluid (found at walmart for $4.46/quart)

Fire it up and crank the wheel lock to lock
Check fluid level and top off as needed.
Check for leaks and repair as needed.
Done!
System takes about 34~36 oz of fluid... 1 quart is really all you'll need.
