Water pump AISIN or OEM BMW

If yours is the later style timing kit, get the Aisin kit from Rock. That kit is ALL OE supplier, including an Aisin water pump.

Just wanted to update the community that it took me about 1.5 hours with me taking things slow to change the water pump on my Kentucky made 2018 Camry SE with 165 miles. I changed the water pump with an Aisin model with a new seal as well as drained and refilled the coolant. From what I understand there is a tsb about a false positive water pump error but in my case it was a part failure. After replacement the check engine code went away on its own immediately on first start.

The aisin on amazon might ship faster ? I would go Aisin tho

The OEM water pump is indeed prone to failure after 100k miles and is easy to replace. It will absolutely cause the death rattle.

The AISIN WPT-190 I bought on Amazon for $142 was was legit OEM. AISIN box etc. Toyota was scratched off the unit as expected.

I would STRONGLY recommend you to buy ONLY a BMW stamped WP. I learned my lesson the hard way and want to help you avoid my mistakes. The main thing that fails in electric water pumps is the electronics, and the ones not stamped with a BMW logo often have these issues.

AISIN WPT-190 is $143 on Amazon. Directly comparing it with one from bought from dealer. Aside from the box, they look identical with the same plastic wrap.

I ordered this water pump from aisin hoping to receive an oem quality part but it seems the molding is not of quality.

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.

Aisin is of course the manufacturer of the defective one you are replacing. So there is that.
