How hard is it to change a water-pump on a 2001 Silverado V-8?

Question

It has a small leak that started this day and it has 60000 miles on it , also new or rebuilt . What is the appr. cost to
have a shop do it ?

Answer 1

If your engine is a 5.3L, then these are it. May be similar to the other v-8's as well. Also says about 2 hours to do it. Course that'd be mechanic time.

Answer 2

Its not hard at all but you do have to have that special tool which is around $60.00. But if you are crafty you can make your own, easily. Don't go for a rebuilt one get a new own. Make sure that it is level before putting it on. We put one on my Z71 and found out it was slightly warped and had to go exchange it after trying to get it tight enough and never could.
