Replacing a water pump requires many steps. You may want to have this done by a mechanic. Or, if you feel confident, I recommend that you purchase a repair manual for your vehicle. Chilton makes a good and reasonably priced one and you will find them in most parts stores. If you have the manual, it will provide step by step instructions and it will include pictures to help.
If you have any other questions, let me know.
