This car has a 4.6L Northstar? If not, disregard my answer.
First, check that your new water pump came with a new o-ring. If not (many brands don't) you need to get one before you begin. You will also need some silicone sealer (suck as GM assembly adhesive or Permatex Ultra-black) and new antifreeze.
Remove the air cleaner, then the upper radiator hose, and then the (small) water pump drive belt.
There will be 1 or 2 small brackets in this area you need to remove now.
Then, unbolt the water pump housing (cover over the water pump.)
Using a Northstar Water Pump Tool, rotate the water pump clockwise to remove it.
Remove the old o-ring and put a new one in place using a dab of sealer to hold it.
Now put everything back together and fill the cooling system.
