The pump is located under the smooth pulley with no ribs. Remove the belt by unloading the tensioner, then remove the 4 bolts that attach the pully to the pump. The pulley may be stuck to the pump, so spray some penetrating oil on the pulley to pump hub area and let it soak. After a few minutes, you should be able to tap on the pulley which will dislodge it from the pump. There are 5 bolts that hold the pump to the timing cover. Remove the bolts and the pump. Clean all the old gasket material away using a scraper or razor blade. Install the new pump and reinstall the pulley and the belt. You will need to fill the cooling system by opening the bleeder screw on the top of the fitting above the pump and possibly the bleeder on the tstat housing where the upper radiator hose meets the engine. Open both of these bleeders while you fill the radiator. Only close the bleeders once coolant comes out of the bleeder. Now it should be alright to start the engine. If you don't bleed the air this way, you will overheat the engine.
