How's Aisin?
Best WP on the planet. A guy on the ClubLexus forum cut one apart to examine the design of their mechanical seal. He is a very knowledgable fellow who has worked in the automotive repair business his whole life. He said the Aisin WP is, by far, the best design with the best quality of any WP he has ever seen. I installed a NAPA WP on my 99 Avalon which I believe was a reboxed Gates unit. It was loud as heck. I replaced it with an OEM Aisin which was perfect. I replaced the original at 85k miles while I was doing the TB. Looking back I wish I would not have spent the time and money to do what I believe was unnecessary PM work. I would say factory Aisin WP's will pretty much last as long as the engine.
We would second this ! There are a few Camry's in the family with mileage over 200K,
specifically 225K and 268K. While the belts and hoses have been replaced, the water pumps have not. Absolutely no noise or evidence of weeping. If and when they are replaced, it will be with Aisin water pumps.
