Engine/Transmission (1998.5 - 2002) Water Pump Life Expectancy

[rmrc]

What would you estimate the life expectancy of a water pump should be taking into account that the coolant is changed as per normal schedules?

I can tell you that the WP on my truck had already been replaced when I bought with 69k on it?

I would guess the average miles before failure would occur between 100-150k - assumes good maintenance. I'm sure that some get replaced earlier and lots live forever.
