Perfect fit for 2008 is250. Genuine aisin water pump 💪

I'm very happy with this part. It was identical to the original part. Much less expensive than going through the dealer, of course. It certainly isn't an "easy fix" but it's a very do-able DIY job to replace a water pump. It was one of those very rewarding fixes because of the dramatic change in engine noise, and coolant leakage.

This was a bit cheaper when I purchased it but it was a perfect fit. Great quality. Zero issues and super quiet.

Item came on time. Works well after 1 week. Let's see how it'll hold to. 2008 Lexus gs350.

Replaced this myself this weekend and the part fits great and sound of rattling bearing is gone. Toyota is scratched off on the part but it is still OEM part. Comes with the gasket and seals that need to be replaced as well. Don't take it to the dealer to do this if you are somewhat mechanically inclined. I was able to change it out myself and save about $600. I used this DIY on club lexus: http://www.clublexus.com/forums/is-2nd-gen-2006-2013/725467-diy-how-to-replace-the-water-pump-on-the-is-250-a.html I also replaced the thermostat and serpentine while i was at it. You have to take these off anyways while replacing the pump. Make sure you order two gallons of toyota super long life coolant too. You will have to drain it out.

Was concerned about they would remove the Toyota and Asian labels. Received one with only the Toyota label removed which make more sense. Compared with OEM part’s picture, the differences are the design of pulley mount and bleeding part. It could be just new designs. I spent a whole afternoon to replace the water pump, thermostat, and radiator cap . Compared with the old pump, I could feel that they were both well made. Upon the review, I have put more than 400 miles on the new pump. No leak. No noise. Literally saved a new iPhone gift money for my wife. Totally worth it. Update on 2025 June: 4 years with more than 25k miles on it. No problem at all!

If you need a water pump for your Toyota get Aisin and forgot about overheating .

As soon as my 2006 IS250 hit 90,000 miles, my water pump started to whine. I took my car in to a local Lexus dealer for an unrelated maintenance and the dealer advised me that my pump is ready to go. He quoted $980 for replacement of just the water pump. Dealer also suggested I change the serpentine belt for another $200, even though my belt looked fine. I thought $1200 was a bit much so I told the dealer I'd like to think about it but I really wanted to check and see how much other mechanics would charge. I never did call another mechanic, but rather I decided to research this to see if I can do these repairs myself. Club lexus and youtube are great resources, but I admit I was quite hesitant to tackle on this repair as I am not mechanically inclined. I am more of an office guy as I am really good on spreadsheets but not on cars. However, I wanted the satisfaction of being able to do this myself. After I bought this pump, a serpentine belt and tools, I watched, almost to the point of studying, the youtube videos several times and read the club lexus instructions to get familiar with the steps before tackling on the actual job. This water pump looks just like the OEM product, except with the model number scratched off. Overall, this job took me just over 4 hours to do the repairs. I think dealer said it would take about 3 hours. Take pictures along the way is helpful just in case. It's been about a month since I made the repairs and so far so good. The pump is holding up nicely and I saved enough to purchase a trip to Hawaii. Aloha!

No issues, high quality, just like original.

Perfect! why pay 300+ tax at dealership when this is the same part for half the price. AISIN is perfect. (90% of all toyota/lexus is made by AISIN. This is trusted. If you notice a grinding/shaving marking on your product is due to "Toyota/Lexus" marked on it that has been removed for legal reasons. Fits perfectly. now see how long it lasts.

Replaced old water pump as it was making noise. New water pump solved issue and runs well

its the stock toyota waterpump, perfect fit.
