Hi guys, how do you empty the power steering fluid on my car?
the level always stays at the same mark, just wondered if you have to empty it every so often and put fresh stuff in?
have ordered some Forte power steering additive, should i add it to my old fluid, or empty old stuff then add it?

only asked because i get a slight "noise" when turning full lock to the right hand side
i dont think its anything to worry about, car drives like a dream, tracking is fine etc etc
recently had 4 tyres put on.... and it still does 120mph on the M40 with NO juddering etc.........er......not that i do that often, lol
