I, personally, have no experience with the Zetec engine, but as a side note:
My wife owns a 96 neon, 4cyl, and the WP is driven by the timing belt, on the lower front of the engine, on the passenger side.
I had to follow those exact instructions to remove hers... I had to remove the top right mount bracket, and I had to get a damper pulley remover, take off the timing belt and then remove the waterpump...
Make sure to mark the timing location on the crankshaft in at least two locations, and then reinstall according to that.
To lock the pulley in place, we used an iron bar shoved through an eye in the pulley itself, and it wedged in to the engine. A little elbow grease from me, while dad loosened the pulley nut, and it was good to go..
Afterwards, I decided that is the WP ever goes out again, I will be "totalling" the car out... screw THAT $H|#...
