Water pump Gates or OEM BMW

I used a Gates kit which seemed good quality and included a water pump, tensioner and idler pulleys.

Same shit different box. Sometimes the aftermarket takes care of issues as well like bmw and older Audi/Vw plastic water pump impellers, where most aftermarket ones are metal.

Just buy the wole WP+ housing as an assembly. Who cares if it's OEM. I install Gates WP/Timing belt kits on many other cars and they are excellent. Better than OEM.

Gates is the brand everyone get and refers to for the water pump. Good quality and cheap enough. If you can't get gates. There are two main impeller designs. Cast and sheet metal tabs. Supposedly the cast impeller design performs better. So if you're ordering from a generic parts store, make sure it's the cast impeller design (but the sheet metal design works just fine).

Last time I got a new Gates water pump (made in china) the flange position on the shaft was a little different than my old one but it was close enough.

Gates waterpump broke in 2, the base is still mated to the block with all the bolts in-tact

This has happened to my husband. He drives 2021 m340i with 17k miles. Water pump exploded last night.

Gates water pumps have been going downhill. I bought one for a Toyota Rav4 v6 and it started leaking after two months of service.

The new Gates water pump installed last month started leaking. I have only driven around 1000km. Does this happen a lot for Gates pumps?

Years ago I would use the Gates kit on my 03 Evo with no issue, but a few years back I had a failure (from a different component) after 19k miles and the Gates pump was weeping when I removed it. The shop I use also doesn’t recommend them either so I go OEM for the water pump anymore.
