Or use cheap parts. Not all water pumps are created equal.
Tell me you've never red-lined a holden V6 without telling me you've never red-lined a Holden V6.
Shame to replace this one, feels perfect with 60K kms on it. A German made Hepu brand.
Lies! My VR reached at least 4300rpm before it started feeling like it was going to throw a rod.
This. Cars are engineered to last the warranty period and (hopefully) a bit longer, but there's a reason the warranty period ends. If cars had to be warranted for 10-20 years they'd be built a lot differently. They'd also be a lot heavier, and likely a lot more rudimentary.
I had a VL with a RB26DE head on it. 8500rpm was fun with a crappy live axle.
This!In the BMW scenario, you could consider (from an enthusiast owner's point of view) it's actually good thing as there's a mechanically superior alternative available. As to it being cheaper, yeah - when you're not running a dealership, arrange international distribution and stock holdings, or have to provide (easily accessible) warranty it's easy to sell things at a lower cost. Yes, it would be nice if it didn't have the fsult to begin with - bit there's not too many mechanically flawless sports cars out there in the real world. And you can always buy an 86/BRZ instead if coolant pump reliability is your jam, just prepare to be sad when you have to change the spark plugs.
That's the least of their worries, I bet BMW is making a living out of replacing the leaking oil filter housing o-rings.For anyone interested in why you shouldn't own a BMW past its warranty period.
This is a 2000s M3 (E46) water pump.
They haven't improved since then.
This is a 1980-1990s Nissan RB series water pump next to it's fancy N1 motorsport brother.
Note that Nissan reduced the number of blades by 1 in the N1 for high rpm racing.

If you run genuine water pumps and genuine coolant, water pumps seem to last for years. The over-tensioning of belts is probably the biggest killer, even with the spring loaded or automatic tensioners because sometimes they get sticky and tight.View attachment 408551
Just pulled this off now, all this water pump talk got me inspired
But it’s timing belt driven, so off it comes. Belt pullies also felt nice, but plastic so off they come too…
That's pretty scary. How much of that is due to having a cast impeller vs a forged/stamped one.
I ran a modified VN V6 for years, tyres used to last me a couple of months, I bounced that motor off the rev limiter nearly every day .
How dare you skite you got a good one!Lies! My VR reached at least 4300rpm before it started feeling like it was going to throw a rod.
Great combo, some serious power made with that arrangement and some hair-dryers.
If this was an accessory belt driven pump I would totally have left it in. But it’s only a $40-50 pump so not worth not changing while doing a belt.
Except if you track a BMW M Motorsport car where plastic impellers have been known to explode and the warranty won't cover you for track use. Audi, VW and non GT Porsches are also track shy.
Hey what about Toyota GRs and Hyundai Ns? They be covered too. I like Porsche's attitude, you just spend $900k on a GT2RS and an extended track day is mandatory for delivery!
