Replacing power steering fluid

[cinquecento]

Hi All,

Will be changing my Gearbox oil this weekend (T5).. and figure I'll have enough ATF left over to do the power steering too.

How do you drain the power steering fluid?. Is there a special bleed valve on the rack.. or can I undo a lower hose, left if drain out and simply refill.

Any air locks/traps to be aware of?

Many thanks
