I done mine recently.......Wholy Crap.....Pay someone to do it.
The water pump is part of the timing belt, What a job! you may even have to lift the engine a bit so it will clear the frame, when taking it out.
I got mine all back together with a new pump, but it idles rough now as I got the timing belt off a bit.
Really......Pay a professional , its worth it.
It dep[ends on exctly which engine you have as to how difficult it is, Get a manual you your car and do the job correctly .
if its a 4 cylinder, its located inside the timing case.
Check autozone.com it tells a bit about it. some engines you have to remove the timing belt so its not a very east job.
you undo the tire housing and pull off the exaust manifold. replace the muffler fluid and then your done
remove belt pump is accessable remove bolts make sure coolant is drained first replace
the library should have a shop manual for this vehicle :)

Look at the belt on the engine, then look at the pulleys. The water pump is behind the pulley without any groves in the pulley.
