I just did this.
There are 4 13 mm bolts that hold the water pump to the block.
There is a bracket that has one bolt to the water pump and two bolts that thread into the AC
There are three hoses a small one underneath and a larger one underneath the other one on the upper side and to the front.
That is all that has to come off the car as far as the getting the waterpump completely disconnected from the car.
Now here's the "tricks"
Get a piece of paper and draw out the way the belt is routed.
Take the belt off with the serpentine belt tool.
Jack at least the passenger side of the car up, put it on a jackstand.
Pull the wheel
Pull the front piece of the wheel liner.
It has two screws that attach it to the back piece
It has one screw holding it to the fender
One screw holding it to the lower valance.
This gives you access to the three little bracket bolts that attach to the AC
It also gives you access to one of the waterpump bolts that is a bitch to get.
It gives you better access to the two hoses on the lower side.
Tools required are 10,12,13 sockets. Shallow and deep if you have them.
A 3/8 Universal joint ,a couple of different size extensions.
Long needle nose and a pair of channel locks
A tool to put in the hoses to break the seal.
This is the 3rd pump I have put on my 2000 Duratec. I changed it at 100K, 200K and it just went out at 89K because I ran it dry when I was changing the coolant out.
Anyway on the two lower hoses, I removed the factory squeeze clamps and put worm gears on there. That made it a lot easier to loosen and tighten the clamps with a socket,u joint and extension. Make sure they are pointed out so you have access to them.
