If it has a 3.4 liter engine in it, the water pump is bolted on the passenger side, front of the engine, it has a pulley that is completely smooth on it, with 4 bolts. the bolts are not very hard to remove. once you take the bolts out of the pulley, it should pop off, but might have some rust around the center and you may have to gently pry it off. There are obvious steps i skipped, like Removing the belt, she shield over the water pump and draining the coolant.
