I changed mine last winter after the SOB was dripping on me for a while. It was pretty straightforward.
Remove the intake and upper shroud of the radiator fan. Then just unbolt the fan and the water pump is right there behind it with some more bolts waiting to come off. Make sure the surface is cleaned WELL of all gasket material. Also, make sure your radiator is drained before attempting all this, . Then apply gasket to new pump and reinstall. The trickiest part for me was putting the pump back on and bolted without smearing the liquid gasket all to hell, took me a couple tries before I got a satisfactory job. My trick that worked was to tape all the bolts into their holes on the pump so when I install the pump the bolts being there allowed me to center the pump precisely and then rip the tape off and start each bolt one at a time, then spin them in to ease the pump on. And since you're dealing with a gasket, it's probably a good idea to make sure you use a torque wrench unless you are good at winging it.
A lot of people have had trouble with residual air in the system after a complete drain. I read up on their experiences and when I refilled the radiator I parked the car on a VERY steep incline (hood uphill) and let it run with the rad cap off and bleeder open until the needle started to rise, then shut off. After that I topped it off, closed rad cap and bleeder, and did some tests with my eye on the temp gauge.
It took me maybe 3 hours of work in total. There is really no reason it should take that long, but I was going very slowly/deliberately, triple checking, and kept running in to check the FSM for torque specs or what have you. I just wanted to learn about the car and I had some free time. Not trying to scare you off, but this is something that if it is done incorrectly, you basically have to start from scratch. So if you're thinking of doing it youself, make sure you do your research ahead of time.
