Reviews of AISIN parts For Business

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

I have installed them in two rebuilt, and they are working perfectly fine

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.

Got the Aisin kit on mine. Just hit 35K with it. So far so good. I used the belt that came with the kit.

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.

The water pump is probably the one part on any car I wouldn't cheap out on. Just get an Aisin as the other commenter said.

Aisin is good, I’ve run them on both of my Acuras with no issues.

Aisin. The bearings in the idlers are better, the tensioner is better, and the water pump wont fail on you in 20k miles.

I just replaced the water pump on my 2011 today. Took me about 1.5 hours and was 150$ from Amazon. Aisin pump.

At this point the entire clutch kit gets warrantied and replaced with and Aisin kit. I drive it around 200 miles. The noise is still there, but now there's also a higher pitched metal on metal ring/chatter and the original ratchety sound is less frequent. The pedal still feels like absolute shit. There's still a clack.
