Im in uncharted territory here. My GM truck has 120K and the water pump has not failed. How long could it possibly last? I need to change the anti-freeze this year but doing both at the same time would be preferred. I was thinking of a preemptive strike but would reconsider if people are seeing a lot more miles out of them. Thanks.
It’s impossible to tell. Some only last 50k some will go 200k. Most will suggest just letting it go until it fails.
Mine is 210k and still going strong.
210?! That’s great! I have always had them fail under 100k so this is a pleasant surprise.
Between 2 Astros, 2 express vans, and a tahoe had one water pump last 150k. I’d replace if it were mine.
I’d absolutely replace at any convenient point after 100k. It doesn’t owe you anything at that point, but having it start to fail right before or during a big rip would be a major PITA and a hassle most of us don’t need.
This is yet another item that I found out my local shop will do for far less than was quoted to me by my local Chevy dealer. It really pays to check around on stuff like this. I got my struts done with a Monroe lifetime strut and alignment for 27% less than the dealers quote using a GM part.

My buddy has a lift and will do it ( I will help) so price is not an issue.
I’ll just do it this summer. Like mentioned I dont want to have an inconvenient issue with it. I just replaced my battery for the same reason. I dont care to get stranded setting a new personal record.

I have noticed that in all my post-2005 vehicles (we’ve had 5 vehicles made after 2005), the batteries go from working to stone dead, no hope of revival in 1 day.
It used to be you’d get about a month of warning where the vehicle would “load down” when starting in the morning, but I’ve had 5 batteries go from working to absolutely no sign of life overnight. Just had my SUV and my mother in law’s SUV both go stone dead this summer within a week of each other. No amount of charging or jump starting would get even 1 more start out of them. Dang good thing I replace batteries myself anyway, 2 quick trips to Sams Club and we were good to go.
So yes, IMO batteries are now a deal where if you think it’s been long enough, it’s been long enough.

I wouldn’t recommend replacing the water pump just based on miles alone. My GM 5.3 has 250,000 on it and the original pump is still going strong. I’ve seen many new aftermarket pumps fail within a year or two. I honestly think the pump on your truck is a better part than an aftermarket replacement. The fact of life is that vehicles will break down. No amount of preventative maintenance will ever guarantee that you won’t have an issue. I’m a firm believer in not fixing if its not broken. Flush the cooling system and run it!
I sold mine with 243k and it was still original.
I have had odd experience with batteries failing on 2000’s vehicles. I think they start so quickly, you never get to hear that battery low and the starter struggle like you would when you had to really crank and crank to get the car started.
I’ve has to replace them at 60k and seen others last over 200k. No pattern to GM water pumps. Batteries you can test and usually get a read on if their lifespan is close to coming to and end.
Very interesting info. Maybe I will ride the pump out since some of you are seeing them go past 200k. I am definitely changing AF once it gets warm out.
I hear you about the batteries. I was lucky this time and got a “warning”. It hesitated every so slightly a few times when cold so I jumped on it before complete failure.
