Changing a water pump is pretty basic. Since the coolant system is a closed system you only need to be concerned with that system. For instance you since you have to mess around with it anyway you might as well change the thermostat and flush the coolant system. Make sure your radiator hoses are in good shape and that's about it.
If you have basic mechanical skills and tools you will have no problem replacing a water pump.


As far as information with the actual replacement there are a number of experts here including myself that could explain how to do it.
However no matter how good our explanations are it just can't compare to a good repair manual.
A repair manual for your car at Auto Zone would likely cost between $12 and $15. It is a great investment if you are going to keep your car for any length of time. When you sell, it shows the buyer you took the time to maintain and repair it right.
I personally like Haynes Manuals.
I hope this helps.
