AISIN WPT-803 New Engine Water Pump with Gaskets - Compatible with Select Lexus ES350, RX350, RX450h Toyota Camry, Highlander, RAV4, Sienna, Venza

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.

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.

Fit perfectly, works great. This is literally the toyota water pump with the name Toyota ground off ... same great quality, US Made part. Will use these as my standard replacement. Learned my lesson using a much cheaper water pump, this is a big job and the $50 el cheapo pumps will leak out the weep hole within a year.

I have confidence that this is a good unit (time will tell), judging by the gaskets that sandwich the water pump. The gaskets have a black coating and a raised ridge that will get compressed when the bolts are tightened, sealing the water pump. The water pump that I removed was sealed with silicone and appeared to be leaking slightly. Take care during the install to tighten bolts slowly and evenly around the water pump. For my 2GR-FE torque is about 15ft lbs for the 12mm (head) and 7 ft lbs for the 10mm bolts, that's not much pressure. Check the torque specs for your application and use a torque wrench as much as possible but because some of the bolts are almost inaccessible, you'll probably have to tighten a few by feel.

Great oem part came with gasket and o rings although the the thickness of the larger one is too thin and won’t stay in the groove so I reused the original figure it’s thicker than the replacement and was in good shape I couldn’t get the replacement one to stay in place while lining up the water pump it’s back together no leaks working as it should

Exact fit to vehicle. Funny, original water pump on my Toyota 2012 Sienna was had two words on the aluminum casting - Aisin and Toyota. The new one I bought had Aisin on the casting in the same spot, but where “Toyota” appeared on the original something had been ground off the new part I bought at that same spot that was approximately the same size. I could not tell any difference. Original pump lasted 175k miles, had not failed yet but was weeping coolant so it was going to fail soon. New pump working great so far. Installation was probably not for beginners but was easier than I expected. Took me two days working slowly.

Good quality, it's been 8 months, everything working well. Bought for es350 07

As good as OEM! Asin makes this part for Toyota. Comes with gasket and needed seals. Such a pain in the…back to replace this as space is tight and this requires medium shade tree mechanic skills. But I gotta stress, even if you think you need a new idler pulley or tensioner and/or idler pulley ( you need to buy a complete tensioner unit and steal the pulley off of it , or else you need to remove the AC compressor to replace the entire tensioner—you don’t want to do that.) the water pump is well made. Smooth, and quiet!
