Great pump
This is the upgraded version of the OE water pump that comes in Toyota siennas, everything fit as it should and seems to be working great. Hopefully the upgraded version will outlast the original version but only time will tell. The Toyota service manual says the engine needs to be pulled to do this job, there are a few videos on the Internet that show you how to do it without doing that. The process involves removing the upper torque mount and the nuts from the lower engine mount and jacking up the engine from the oil pan with a block of wood. It's still a timely process, but for the total cost of a little less than $200 for the water pump and the coolant you save a lot of money if you're able to do it yourself instead of paying someone. Just be sure while you have everything undone to inspect your serpentine belt and pulleys because some of those may be due to be changed out also.

AISIN WPT-803 New OEM Water Pump Kit saved the day!
I am not rich so i wanted to do this job with as little $$$ as possible. Since the Dealership wanted almost $1700 for this job, i decided to tackle the job my self. I spent a whole week watching YouTube videos on how to install this water pump on my 2013 Toyota Highlander 3.5L Limited 4WD with 150,000 miles.. The noise coming out of the water pump was becoming unbearable especially in the morning when I start the car. My neighbors could hear the annoying grinding noise every morning and i am sure they loved it :) Anyways, I originally bought a Gates Water Pump (WH061821 from Amazon but realized that I had a small leak after installing the water pump. I tried to diagnosing the leak and took the water pump apart again, cleaned the mating surface, used thread sealer on the long bolts but this didn't work. I realized the Gates water pump gasket may be the problem so i decided to by an OEM water pump. I saw the AISIN WPT-803 New OEM Water Pump Kit on Amazon and read all of the reviews and deiced to but it. I received the ASIN WPT-803 in about 3 days and it took me at least 6 hours to do the job. It's been almost a week and I have no single leak and no more grinding annoying noise and my neighbors are now waving and saying hello to me again :). Things you need to know before you do this job: Don't just change the water pump when you do this job. Put some efforts and cash to it and change the serpentine belt, the tensioner and idler pulley, and the thermostat. also invest in a small toque wrench (I didn't have this the first time and I believe I over tightened the bolts and this may have caused the metal gasket to break and leak). You need to raise the engine a little bit on the passenger side...just unbolt the head bolt to the mount but no need to completely remove the bolt or the mount. I also remove the 3 bolt under the front/middle mount but I did not remove the mount itself. Overall, the AISIN WPT-803 New OEM Water Pump Kit is solid and a good fit for my Toyota Highlander. The price was reasonable and worth it! The job wasn't really hard but you need to be patient and be sure to have all of the tools you need before starting the job.

Works for 2015 Toyota sienna with 2GRFE engine.
This water pump is the newer version of Aisin water pump and look exactly like the original toyota one with a notable improvement. The hub of the water pump is notched at the right places so that during installation the pulley can be wiggled around with a much higher degree to provide the MUCH NEEDED room to install (tighten, and torque wrenched) with the right torque specs. For 2GRFE engines such as the one on my 2015 toyota sienna, it made the installation of the new replacement pump much easier than removing the old original one. The logo for Toyota has been grinded away at the factory so it is sold as Aisin brand. It fits exactly the same with OEM quality. I woild highly recommend this part to anyone who would want to DIY on replacing the water pump. No leak and worked perfectly for the road trip we had. It came with the two gaskets that are needed for the thermostat body and engine.

Great fit
Perfect fit for 2011 Sienna. Same OEM brand also. Original lasts 231k miles! Well packaged also. Job took about 7 hours but also changed the belt tensioner. All were getting a little noisy at that mileage! 🤣. I figured I saved myself $2000 by doing these myself. Recommend getting the gear wrench serpentine belt tool…very versatile and well made.

OEM parts that works
It's been over a year since we have my wife rx350 water pump replaced with Aisin part. The mechanic had no issue with the installation, and we have no issue with it ever since.

Lexus/Toyota upgrade water pump
This is the newest upgraded water pump made for Lexus and Toyota. Where Toyota would have been imprinted on the pump was ground off. It appears to be of good quality and has AISIN imprinted on the casing. The main gasket for the water pump came in the box, but the thermostat housing gasket ,Toyota part #16325-31010. and the Toyota part # 96761- 24019 o ring for the cross over pipe was not. Nice and quiet again no worn bearing sounds.

2011 Toyota Camry
Put this on my 2011 Camry SE V6 after the original gave out at 109k. Aisin is the company that provides the OEM pump and from what I've read they grind off "Toyota" due to resale reasons. Even though they have the picture of the old version up (round circle). They sent the updated version with the cutout design. Came with two O rings and gasket and so far everything is good, no leaks whatsoever. Just like the day I bought it. Installation can be pretty time consuming if you're not familiar with your car but after hearing quotes up to $1,800 I decided to DIY. You don't have to take the engine out but you do need to raise it up -- I learned from CarCareNut on YouTube.

Perfect oe replacement
This pump was an exact replacement for the pump on our 2014 Highlander and is working well. We only got 86k on the oe pump ( I think it was the oe pump)but that’s better than some other Toyota pumps I had. It was half the cost of the same pump from a local dealer.
