Hi Gilly,
the pwr steering hose blew off the radiator one cold morning about a month ago. I took a cab to the local mb dealer and bought the power steering fluid.

I then refit the hose and tightened the clamps.

Then I filled the power steering reservoir with the fluid - just about 1/2 the bottle.

Did I need to do anything else? I haven't had problems yet, but should I have bled the system and is there some procedure for filling?
