Hello bugzdagr8: My name is Roger and I will answer your question. Yes you do need a special tool to remove the water pump. The GM tool number is J38816-1A. You should be able to get one from a tool dealer. Snap-on ,Mac or Matco sales them. Most parts stores sell them also. The water pump has a lock plate that must be turned. Please rate the quality of your answer. This is how we know you received the correct answer.Should you need more help please just ask. Thank You for using FixYa. Roger

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.
