Water pump AISIN or OEM BMW

That\u2019s what I have in mine and I\u2019ve had zero issue with the water pump.

Water pump and timing belt done with OEM Aisin kit (March 2024)

Just replaced my water pump and thermostat on my 2015. Aisin pump, which is oem was $150 on amazon. $40 for the thermostat. Super easy to replace yourself. Especially if they want $4000 to do it.

My impression was (recommended by many) this specific seller had everything OEM, water pump was the correct Aisin one.

RockAuto Aisin with the logos ground off. That’s when you know it’s the real deal.

Aisin only. It's the Oem.

The fel pro gasket set and head bolts + head bolt tool will be close to 300 and then you'll need RTV sealant. Another probably 200 for the Aisin water pump.

The cooling system is the major weak point (ask me how I know) - water pump failed before 70k (changed under warranty)

Replaced with Asin, failed in 7k miles. The propeller disintegrated on the second one.
