How to drain all the hydraulic fluid from the power steering system

Disconnect the return line to the reservoir,put the return hose in to a gallon container (add a longer hose and fitting if needed) jack up the car so the front wheels are of the ground. turn the steering from side to side while adding fluid, get a friend to start the engine and slowly turn the steering from side to side while you keep adding fluid, keep doing this until the fluid coming out is clean. Reattach hose drive and recheck fluid level. There is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate http://bit.ly/AllData_Repair_Manuals_Online

Without seeing it, I would try the one higher off ground level. You want the one that pupms fluid back to the reservoir....perhaps trial and error.

Hey I live in RSM email me I would like to talk to you about service places and common problems with my own 2003 AMG SL55. I am new to this area so I don't where to take my car for service. Plus I have become interested in repairing minor problems that I am having. Really annoying stuff that seems like it could be fixed easily. Thanks
