AISIN WPT-137 New Engine Water Pump with Gaskets - Compatible with Select Lexus GS300, GS350, GS450h, IS250, IS300, IS350, RC300, RC350

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.

The only pump you should use on Toyota or Lexus vehicles! Period!

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

Price is very competitive as it similar to an original product, no hassle on fitment as it assembles perfectly and intended. Installing will be easy if all preparation is considered; proper tools, parts, and safety precautions working on vehicles.

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!

been well over a year. no leaks or issues at all. I'm not a mechanic and never changed anything on a car myself. but with you tube videos and a socket set. I got it done myself in half an hour. half an hour because i already learned the area when figuring out what the jddue was. otherwise insay an hour max. very simple as long as you're not an idiot and a chick like man. saved me at least 200$ in labor. and I say at least because my old friend wanted 200$ to do the job. dealer is probably 4-500. if you do it yourself. don't back the car up like the videos say. you can drain the radiator fluid by just sticking your hand in and raising the little valve which drains everything. just out a fun under your car to catch it all.

The original water pump on my 2007 IS350 developed a rattle. It lasted 110k miles. Plan was to bring it to a shop to replace until I heard it'd cost nearly $1k to do the job. Ordered this part, went full on DIY, and replaced it with the help of DIY info and videos. Can't thank those meticulous brave souls who documented steps so well. AISIN is an OEM brand Lexus uses. This part is an exact fit. Some reviewers mention that it is not genuine AISIN because of shaved off stamping. FALSE. What they shaved off was the Toyota stamping for legal reasons. Since this is a genuine part made by AISIN for Toyota, they have to shave off the Toyota stamp because it's not sold as a Toyota part through the dealership but as an OEM part.

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.
