Sorry mate, i thought I had completed it.
There is a hidden bolt you need to undo! if looking at the pump from the front it's on the right of the pump and is about 4" in so you can't really see it. get an extension on your socket and it should be ok, this will release the pump and it will swivel down if you have undone the others

Do not over tighnen this bolt when you put it back on!
O yeah, may aswell replace the alternator belt while your at it as this has to come off first to get the power steering belt off! (I think, don't qoute me)

Good luck
