Water pump OEM BMW or Hepu

Graf & Hepu brand water pumps are both metal impeller high quality oem suppliers

I also used a kit from FCP Euro about 8 years ago and it included a HEPU water pump that worked fine for 7 years until I dismantled that car.

my hepu has been in for 9 years with zero issues

Hepu pumps are the best.

Water pump if stock would have a plastic impeller known to fail, but you can find metal impeller options from Graf and Hepu brands and from other aftermarket brands too.

Buy the M340i new and prepay your services. Great on gas but insurances and tires have been expensive. Water pump blew at 48k.

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

I am dealing with a similar issue right now on my CJAA which I changed the timing belt in April this year. Leaking from same spot. Hepu waterpump.

a Hepu which went seven years/60,000 miles before it started leaking. I think the additional mass of the metal impeller put more stress on the bearing and seal.

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.
