Water pump Gates or OEM BMW

Update: it was the water pump. Got a new Gates water pump (screws and gasket included). Installed it, no sealant or anything. Works flawlessly. Not a drop anywhere.

I used the gates kit from rock auto including the gates water pump… Car seems to be driving fine for the past few thousand miles since install.

I usually end up with Gates or AC Delco.

Can't go wrong with a Gates pump.

I only use gates kits on any HDI I work on. Out around 30 fitted to friends and family cars I had one water pump bearing fail after 4 months they changed it with no issues but as it was a home fit not garage no labour cost offered no other issues.

Did hear Gates did have a bad batch of 2.0 Blue HDI OEM water pumps with impellers coming loose

It’s still baffles me how BMW can’t get a quality water pump on its vehicles.

I don't trust the BMW oem pumps any farther than you can throw them

Good choice on going with Aisin. I had to redo the job on mine after 2 months when the shitty Gates water pump started pissing out the weep hole. Will never buy another Gates pump again.

Did a gates kit on mine. Water pump is leaking after 60k miles.

The water pump had a micro leak that would spray coolant on the air box. Never enough to make me want to go through the trouble of replacing it.
