This takes moderate skill and you will want to replace your timing belt and your tensioner at the same time. The reason to replace both of these is that they are prone to failure and you will have them off anyway.

Remove coolant from bottom of radiator petcock. remove shroud and radiator.

remove fan clutch and fan. remove acessory belts. remove timing cover and thermo housing.

you will now see the timing belt going over the idler, cams, water pump and crank pully.

put the #1 piston at top dead center and your two cam pulleys and crank pulley should be at the marks corresponding to the block. mark them loudly anyways so you can see them better. try real hard not to move these three.

loosen tensioner and remove belt. unbolt water pump, cleanup face and install new one.

reverse order assembly. make absolutely sure your cams and crank are in the correct relationship when the belt goes on. It is a good idea to replace the front seal too since you are into it this far.

I left out some minor details but you'll figure it out or you shouldn't be doing this.
