The reason no one has replied is cos you don't say what year and car it is. Early cars ran on Dexron 2 ATF and the later cars on VW mineral oil.
Depends how well you drain the system. I would guess (and I mean guess) at around 1 1/2 to 2L. Christ you don't want much do you
lol golden it owuld be alright if she was doing the work! got to replace the pump hoping that will fix the dodgy power steering. so will drain it as much as possible
this ps system is p****** me off. unless i can get 17mm brake pipe spanner i'll give the pump to garage to change! never had any prbs with the others
