i bought all new fluid form mercedes ...(about 80 bucks...yikes!) but how do i drain the old stuff?

this is info on the W123 chassis, by Steve Welty dtd 1-31-01:
" . . just remove the top of the holding tank and unscrew the metal fitting that feeds into it. Syphon out all the fluid in the holding tank and fill it with fresh fluid. Connect a hose to the metal end and put the other end into a bucket. Have someone start the engine and you keep feeding the fluid into the reservoir until the outcoming fluid runs clear. When that happens-turn off der engine! Change the filter. Reassemble."

Don't let the system run dry.
ps was just on my mind, that fluid runs $9.50 a liter jug - I just bought some that's how I know.
