99 Venture 3.4L replaced water pump at 85,000 miles

Mine leaked at 87,000. I replaced it to find that the one on there
had been replaced once already. This is a real pain on a 1993 3.8
Buick Lesabre since in their infinite wisdom, GM engineers make it
necessary to raise the engine and remove the right motor mount which
is difficult and also, the only place to jack up the engine is the
harmonic balancer or the oil pan. Work on a GM vehicle and you soon
learn they are NOT built for ease of repair, but more for junk yard
fodder.
Jap vehicles with their timing belt driven water pumps are bad enough,
but GM keeps up by turning a 25 minute task into an all day job; and
the Jap pumps seem to last lots longer that GM pumps.
Automotive engineers must rotate from company to company since that's
about the only way I can conceive of that inept engineering can be so
widespread.

So far I don't see a pattern. Some seem to fail fairly early and some last
well into the 100K+ mile range. Based on these responses it seems to me
that it would not be helpful to just replace a water pump that is working
fine. You may replace one that would have given you 150K miles of service
with one that will only give you 40K miles...doesn't make much sense then.

1990 Chevrolet Celebrity with a 3.1 V6

Replaced water pump 2 years ago at about 125,000 miles. May have been
previously replaced.

Rarely have had to replace a water pump on any of my vehiles. My 1990
5.7L Suburban needed a new one at 109,000 miles and my 1985 2.5L
Celebrity got over 102,000 miles on its water pump. The 1987 2.8 Liter
Blazer needed a new pump at 120,000 miles and now has 90,000 miles on
that pump. The trick is to maintain the cooling system as well as you
maintain the engine oil or transmission (do it on a regular basis).
