Engines
CAUTION
When draining the coolant, keep in mind that cats and dogs are
attracted by the ethylene glycol antifreeze, and are quite likely to
drink any that is left in an uncovered container or in puddles on the
ground. This will prove fatal in sufficient quantity. Always drain the
coolant into a sealable container. Coolant should be reused unless it is
contaminated or several years old.

Remove the radiator shroud halves.
Remove the fan clutch and fan.
The fan clutch bolts are left hand thread. Remove them by turning
them clockwise.
Remove the power steering pump belt.
Remove the air conditioning compressor belt.
Remove the vacuum pump drive belt.
Remove the alternator drive belt.

Remove the bolts attaching the water pump to the front cover and
lift off the pump.
Thoroughly clean the mating surfaces of the pump and front cover.
Get a hold of two dowel pins - anything that will fit into 2
mounting bolt holes in the front cover. You'll need these to ensure
proper bolt hole alignment when you're installing the water pump.
Using a new gasket, position the water pump over the dowel pins
and into place on the front cover.
Install the attaching bolts. The 2 top center and 2 bottom center
bolts must be coated with RTV silicone sealant prior to installation.
Also, these 4 bolts are a different length than the other bolts. Torque
the bolts to 14 ft. lbs.
Install the water pump pulley.
Wrap the heater hose fitting threads with Teflon® tape and screw
it into the water pump. Torque it to 18 ft. lbs.

Hi:
I don't know exactly what engine you have, but here is the basic process for changing a water pump:
Drain the radiator . loosen and remove all belts.
Remove the fan assembly, and the shroud from the engine side of the radiator.
Remove the radiator.
Inspect and remove the radiator hoses from the engine. The waterpump is held in place on the engine by approx 5-6 bolts. Remove all and carefully remove the water pump from the engine.
Clean the engine surfaces of all old gasket material.
Install the new waterpump and gasket with the recomended sealant as needed. Install all bolts and torque them to the proper tightness.
Install the radiator, hoses, shroud and fan .
Install all drive belts.
Fill engine and radiator with fresh coolant,
start engine and check for leaks.
Hope this helps,
