how tough is the water pump change
 

I've got an '02 SE and the pulley on the water pump is loose and making much noise. How big of a job is this? Thanks.

Not real hard. A few hours and no special tools needed. Just drain teh coolant, remove teh belt, remove teh power steering pump, careful you don't drop it, the oil pressure sensor is right below it. Remove the 7 or 8 bolts and it comes out.
