alright it is very tidious to replace the water pump... u first have to take off the engine mount and set it aside.. make sure the engine is supported a little by a jack or someting. u then have to remove the belts for power stering and ac if equiped and alternator. then take the pullys off for the water pump.. make sure your engine is at top dead center with ## marks alined on crank pully and cam pully/pullys. then u want to remaove the crank pullys so u can remove the timing cover.. after all these steps are complete lossen th automatic tensioner and remove it, that will alow for you to take off the timing belt... when you are finished getting the timing belt removed you want to losen all bolts for the water pump and then remove it... make sure to take a gasket scraper and get any old gasket material or rtv sylicone of the bloc...
