davo, i replaced my water pump on me 1.6 driver, was piece of pi55,
this is how i did it maybe an easier way
1.undo and move alternator out the way(1x6mm allen key in bottom of alternator, 1x 13mm nut,used to tighten the belt)
2.disconnect all the water hoses from the water pump(3if i remember correctly)
3.there will be 3 13mm nuts holding water pump on undo tap the water pump with small hammer and it should just fall off.
fitting is reversal,
i would buy a whole pump if u think urs has gone, taking em apart is not worth the hassel trust me i found it out, fit it with new o ring and job done.
good luck hope i aint confused u
