mike28117, one quart of FeBi 02615 or Mercedes 0009899103 should be enough.

About a quarter of the old hydraulic fluid remains in the hoses and cylinders if you empty only the reservoir. For a perfect flush (if you are not having us rebuild all the cylinders this time), you want to empty the reservoir, get the sludge off the bottom of the reservoir, and then cycle all top cylinders manually. Cycling the cylinders manually will push the old fluid into the reservoir. If the reservoir is empty or near empty, then the cylinders will be sucking in air, which is what you want for a perfect flush.

The hydraulic system is self bleeding. As long as the pump has enough fluid in it, it will produce pressure. It takes some five cycles to get all air out of the cylinders again. On the first couple of cycles, when there is still a good amount of air in the main lift cylinders, you will find the top "falling" towards the windshield. Slow that descent with your hand, or let go of the button as soon as the top picks up speed when coming down.

Thanks for the links. No need to refer to the SLK thread in the future, because the SLK pump fill procedure is quite different. It's actually easier on the Crossfire pump, because the Crossfire pump has a fill port directly on the reservoir.
