I changed PS fluid two months ago. I think to change the reservior is quite
easy.
1) syphon all ps fluid out of reservior
2) Disconnect all hoses from reservior and remember the connecting position.
It's better to mark it with marker or tapes
3) Find all screws fixed reserviors and remove all of them after spray some
wd40
4) Install the new reservior
5) Connect all the hoses
6) Fill ps fluid until full and turn steering wheel to remove air in ps
system.
Things need: Enough ps fluid. Extra bolts
