Unpopular opinion: I think the OEM water pump on the 6.7 Cummins is actually a weak point, but my boss swears by them.
Just had one fail at 120k miles on a fleet truck in Denver last week, and it took the fan clutch with it. Anyone else seeing this pattern, or did I just get a bad one?

Funny how that works, your boss probably hasn't paid the repair bill. The altitude in Denver might be a factor people miss. Thinner air means less cooling, so everything runs hotter and works harder. That extra stress could be pushing marginal parts over the edge sooner than they would at sea level. Seen similar early failures on trucks that do a lot of mountain passes.

My buddy's 6.7 in Cheyenne lost its pump at like 110k. I mean, maybe it's just me but that altitude thing makes sense. Stuff just cooks up there.
