 Can the power steering be damaged if turned with pump not running? w140 with SPS Can the power steering be damaged if turned with pump not running? Turned more than a few times that is... don't know how many turns and for how long. So is it possible to damage the steering box? |

 Generally no, for one specific poorly designed car yes. When the wheel is turned, fluid is displaced from the steering rack / box and it ends up in the pump reservoir. If there is an overfill situation or a low free space reservoir, fluid can be displaced out the vent. My 1984 Ford Bronco will dump fluid if I turned the wheel with the engine off. The specific car I've seen damage occur was on a 1997 ish Pontiac Grand Prix, these used a sealed power steering cap and this particular car may of had an over filled condition. The drive belt broke, car was driven, power steering return hose popped off the barb. ( these are attached with a hose clamp since it is a no pressure return hose. ) If you car has a non vented system, I'd open the cap to release pressure and then once the engine had run / shut off, open int again to release vacuum. |

 I drove my '77 240D from San Diego to Carson city with no power steering belt once. No damage. |

 As a side note, if you have to drive without the PS pump turning, drain the fluid out.  This way you are not displacing fluid every time you turn the wheel. |
