Maybe your Aisin problems are specific to that particular model? I like Aisin for my Honda. I like Aisin for my Volvos. Just finished timing belt on the ‘04 Volvo S80 over the weekend. The original pump (made in 2003) was branded Aisin and Volvo, while the new one was branded Aisin, but had the Volvo name ground off. (See pic)
The original pump had 226K miles on it and it was operating great (smooth, quiet, no leaks). Pretty sure the pump could have gone another 100K, but the new Aisin Timing Belt Kit came with a new Aisin WP, INA idler and INA tensioner, and Gates belt. Looking forward to another 200K+ miles.
Aisin Honda water pump any good?

I got the Aisin timing belt kit on my Odyssey as well. Works fine.
Well in fairness I change the water pump with every timing belt change, so it is usually about 100,000 miles, give or take.
But on my old ECHO with a timing chain it has been longer. I changed out the water pump a while back just because it had never been changed, the old one looked fine though.
Over the past decade, I have installed AISIN timing belt kits with AISIN water pumps in four Honda J35s and one F23 engine. All have gone over 100,000 miles since then, with one reaching 180,000 miles (yes, waaaay overdue) with no component failure other than one slightly leaky hydraulic tensioner. Count me as an AISIN fanboy based upon actual personal experience, not innuendo.
FYI, the Honda Element we bought new in 2003 has the mighty K24 engine with >273,000 miles on the original OEM (Yamada?) water pump. Honda OEM parts are top shelf, but AISIN is high quality aftermarket.

Aisin is just a name/co that I use as a benchmark- is there better? Sure as shyt there is worse product out there. Most jobs on my honda and toyota's are a pita that I want to do once......
I stay away from any Airtex or Carter. IMO, just another Dorman. YMMVSad to see Aisin pumps not doing well with Honda
The OEM pump is $95 from this Honda dealer. It could also be cheaper from other online Honda dealers. Please don't buy it from eBay or Amazon unless it's sold from AND shipped by a dealer. Sometimes dealers actually do sell on Amazon (for example, I've seen Amazon listings sold and shipped by Lee Honda in Maine)
Do you remember if the original factory pump was made by Aisin? Even if a new one from the dealer is made by Yamada now, the original installed in 2006 could've been from Aisin. These problems could've been why Honda switched suppliers.
Since Aisin is Toyota, maybe they intentionally sabotage their Honda water pumps
Aisin pumps seem to be fine for non-Honda Japanese cars.
Would you trust another aftermarket WP for the K24? GMB? NPW? Airtex? Carter? Maybe there's this GMB water pump on eBay if you don't want to spend $100 at the dealer. If GMB still makes them in Japan, you can just order a new one from Rock Auto or a similar site. Otherwise, that ebay listing will guarantee a Japan-made GMB. I don't think GMB is counterfeited as much as Aisin. Confirm with GMB if it's still made in Japan
Partsgeek has the NPW water pump. Partsgeek is a reputable site and uses Worldpac.
I just had a aisin water pump fail after 2 years and 25k kms.
Got the kit from Rock Auto.
This blows my mind. I bought Aisin thinking I was getting the best.
Hopefully these short lived pumps are statistical outliers.
Ya me too.
Sadly not anymore.
Weird. My 03 accord with the k24 had the original water pump till I traded it in at 270something thousand miles. That is unless the original owner ever replaced it before I bought it at 90k.
My hindsight is pretty darn good. 8 years ago I shoulda drove over to Acura and bought the pump from them.
My 2007 accord se with the 2.4 had 386000 on it when I traded it in... It still had the original water pump in it.....
The TSX OEM Water Pump is made in Japan Yamada brand, when I replaced mine at 90K I went to the dealership to buy another one. The Dealership tried to sell me a water pump that said Assembled in Canada on the box. I suspected it was Chinese and re-boxed in Canada. I ended up buying a NPW made in Japan from Napa. Car has 140K on it now, no problems with the pump. I would not hesitate running a Asian or NPW Water Pump. I have run those on my Accords and Integra without any problems. I think you can still get the Yamada pump from https://www.amayama.com/en
I'm hearing a little noise coming from the accessory drive area my TSX. I swapped the bearing on the tensioner pulley, which was definitely on the way out, but it wasn't the noise I was hearing. Thinking back to this thread and the short lived Aisin pumps. ~40k on it at this point. Again, we'll see...

I can only venture a guess and say yes, it's very good quality. My LS430 got a timing belt done with an Aisin kit and that was 8 years and 65k miles ago.
You're reading it here, I won't be having it done next year based on 9 years....I doubt I'll do it in 25k either (factory says 9/90 but when the original was pulled out it looked brand new at 10/86k)

I ended up buying a made-in-Japan NPW pump and swapped it today. 40k miles on the Aisin. Very disappointed in the Aisin. @JeffKeryk
Are Genuine Honda pumps made by Yamada for that application?
