Okay, the water pump is driven by the timing belt so you will have to remove the timing belt too. I would replace it sense it will be off. You need to remove the air cleaner assembly the upper fan shroud all the drive belts and engine fan. Now remove any oil cooler hoses that go to the timing cover, now remove the front timing cover and then align the timing marks (use picture included). If the timing belt is fairly new and are not replacing it then not or mark the direction the belt is on so (which side it out and which direction it rotates) the timing belt cogs will be set as how it is on now. You will also need to remove the crankshaft pulley and such before the timing cover will come off. Now once the everything is aligned now loosen the timing belt tention-er and remove the belt. Now you can remove the water pump bolts and water pump. Put together in reverse order.
