The water pump is tucked neatly under the bracket supporting the blower tensioning pulleys and it's hard to see. To remove the pump loosen the four 10mm bolts and slide the pump out. It may be necessary to tap the pump with a rubber mallet to free it up. Additionally, some coolant may leak out, but that's not a problem. These water pumps seal to the block with an integrated O-ring so there is no fussing with gaskets and/or RTV.
