You need a special water pump tool. you can rent one from Auto Zone. The water pump housing is the bottom radiator hose on the right side of the engine. remove the hose and the outer-caseing, the waterpump is now slightly visable. Use a .5 inch rachet with the Special tool and turn clockwise.

The water pump can be removed without lifting the engine out. But, you should take the belt off with a 1/2" breaker bar.
