How hard is it to change a water pump on a 99 Tahoe?

My water pump needs to be changed as it is leaking and making noise. Is this something I should do myself or have someone else do? If I should do it myself, does anyone have any tips? thanks

Does it have the original radiator hoses and water pump bypass hoses? Now might be a good time to change them. The bottom radiator hose clamp is a little tricky. Its pretty tight down there.

Seperating the fan from the pump can be a pain allso, I used a oil filter strap wrench to hold the pulley and then broke the nut loose.

They do make a fan clutch tool that can be rented that makes it a lot easier to take the clutch off. After you get the clutch off its a breeze.
