I have installed them in two rebuilt, and they are working perfectly fine
Pros: perfectly fine operation
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.
Pros: legit OEM, AISIN box
Part number: WPT-190
Got the Aisin kit on mine. Just hit 35K with it. So far so good. I used the belt that came with the kit.
Pros: good reliability, durable
Mileage: 35000 km
AISIN WPT-190 is $143 on Amazon. Directly comparing it with one from bought from dealer. Aside from the box, they look identical with the same plastic wrap.
Pros: looks identical to dealer
Part number: WPT-190
The water pump is probably the one part on any car I wouldn't cheap out on. Just get an Aisin as the other commenter said.
Pros: Aisin is good
Cons: risk engine failure
Aisin is good, I’ve run them on both of my Acuras with no issues.
Pros: no issues
Vehicle:
Acura
Aisin. The bearings in the idlers are better, the tensioner is better, and the water pump wont fail on you in 20k miles.
Pros: better bearings, tensioner
Cons: water pump fails
Mileage: 20000 km
I just replaced the water pump on my 2011 today. Took me about 1.5 hours and was 150$ from Amazon. Aisin pump.
Pros: 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.
Cons: noise, rattling, pedal feels bad, clacking
Mileage: 200 km
