On our 2000 Ml320, the power steering line at the radiator is leaking enough to where we have to add more fluid once a week. Are the clamps that hold the line a part of the recall on this car in the past? The dealer here says they performed the update back in 2003. Should I just go and get two new clamps from the dealer or replace the whole line, which dosent look pleasing. Also I have been topping off with valvoline synthetic ps fluid. Should this be flushed out and genuine mb stuff put in?
Thanks for any replies.
