the pulley kits are really cheap
but on my mondeo i had to remove the pump in order to get to the circlip, what a pain in the arse that was, but on the bench it was 2 minutes, after i'd parked the car up for 8 months
on the fiesta it looks easier but it's trying to get the part in the first place
i got one off ebay for £15 for the complete pump so i'm not that fussed for themoment
i'll let you know over the weekend how it goes
