Water pump Gates or Pierburg

Pierburg. It’s literally exactly the same just no BMW logo.

Pierburg is the OEM maker of the BMW water pump. Spending the extra for the BMW is ridiculous when they are 100% the same exact same pump from the same company from the same factory.

I have a Gates part with a plastic impeller in my car now and it's been attached to that motor since late 2015 with no issues when it was in my e34 and isn't showing any issues now in my E30.

Water pumps, I tend to stick with OEM now. Gates used to be great but has gone down hill imo.

Gates water pumps failed on both my friend's Toyota Echo and my Sienna, his after under a year and mine in about 2 years. Less than 3,000 miles on my Sienna since pump was changed. Ugh. The labor cost, of course, is the bee-atch, more than the pump cost, of course.

I bought a Gates water pump off Amazon thinking I could go with a name I trust. Impeller grenaded after 5 months and less than 6k driven.

Installed this GATES water pump 5k miles ago…. Pully seems wobbly as fuck, safe to assume it’s already going out? gonna have to find a better brand

I picked the pierburg for all aluminum casing and impeller. They were both about the same price last time I needed to get one. Note that the pierburg failed at not even 10k miles. I replaced with another pierburg chalking it up to bad luck. The only advantage I can think of with the pierburg is the fact that you can torque down the hoses that use clamps and not have to worry about cracking the housing. But in reality doubtful that is a risk. Also it won’t be in service long enough to get brittle enough to matter.

I had a gates kit on my Subaru and the water pump failed and leaked after less than 1000 miles.

The water pumps i’ve seen leak a few times on the v6 hondas.
