Review: 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 desertcart 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 desertcart 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. Review: 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. ## Features - AISIN is the number one original equipment manufacturer of water pumps in the world - AISIN's advanced design produces water pumps with smooth coolant flow channels, efficient rotors, ball bearings, and carbon ceramic mechanical sealing for optimum cooling performance and longevity - Crafted from all new, not remanufactured, components that feature upgraded design and materials enhancements to ensure top performance - Water pump construction materials have been carefully selected for their resistance to common water pump killers - rust, corrosion, and coolant scaling - Gasket included - Compatible with select vehicles (Note: Engine may affect fitment - verify specific fitment details with fit checker above): LEXUS: 2007-18 ES350, 2007-15 RX350, 2010-15 RX450h; TOYOTA: 2005-18, 2007-17 Camry - Compatible with (continued): TOYOTA: 2008-16 Highlander, 2006-12 RAV4, 2007-16 Sienna, 2009-16 Venza ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B008EEZ8A6 | | Automotive Fit Type | Vehicle Specific Fit | | Best Sellers Rank | #37,544 in Automotive ( See Top 100 in Automotive ) #31 in Automotive Replacement Engine Water Pumps | | Brand | AISIN | | Brand Name | AISIN | | Compatible with Vehicle Type | Car | | Customer Reviews | 4.7 out of 5 stars 496 Reviews | | Global Trade Identification Number | 04954514998727 | | Included Components | Engine Water Pump | | Item Type Name | Engine Water Pump | | Item Weight | 3.2 pounds | | Manufacturer | Aisin | | Manufacturer Part Number | WPT-803 | | Manufacturer Warranty Description | Includes manufacturer provided warranty | | Material | Carbon Ceramic | | Material Type | Carbon Ceramic | | Model Number | WPT-803 | | Number of Items | 1 | | Number of Packs | 1 | | OEM Equivalent Part Number | 16100 09440, 1610009440 | | Part Interchange Info | changeable | | Unit Count | 1 Count | | Vehicle Service Type | Car | | Weight Class | Medium weight | ## Product Details - **Automotive Fit Type:** Vehicle Specific Fit - **Brand:** AISIN - **Global Trade Identification Number:** 04954514998727 - **Item Weight:** 3.2 pounds - **Manufacturer:** Aisin - **Material:** Carbon Ceramic - **Number of Packs:** 1 - **OEM Part Number:** 16100 09440, 1610009440 - **Vehicle Service Type:** Car - **Weight Class:** Medium weight ## Images ![AISIN GENUINE WPT-803 New Engine Water Pump with Gaskets - Compatible with Select Lexus ES350, RX350, RX450h Toyota Camry, Highlander, RAV4, Sienna, Venza - Image 1](https://m.media-amazon.com/images/I/71ICRToCR2L.jpg) ![AISIN GENUINE WPT-803 New Engine Water Pump with Gaskets - Compatible with Select Lexus ES350, RX350, RX450h Toyota Camry, Highlander, RAV4, Sienna, Venza - Image 2](https://m.media-amazon.com/images/I/314H9w3rU4L.jpg) ![AISIN GENUINE WPT-803 New Engine Water Pump with Gaskets - Compatible with Select Lexus ES350, RX350, RX450h Toyota Camry, Highlander, RAV4, Sienna, Venza - Image 3](https://m.media-amazon.com/images/I/31hlcFhQJ8L.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Is this fits 2008 toyota sienna?** A: Yes! **Q: Has this pump updated to the new version?** A: Yes, this is the updated version of Aisin WPT-803. **Q: is this the correct fit for the lexus rx350** A: Yes.

No leaks! *by T***R on July 10, 2026* The waterpump on my girlfriend's 2008 Toyota Highlander V6 is making a loud rumbling noise. I watched many youtube videos with how to replace it. I spent the whole weekend Saturday and Sunday working on it. After I completed the job, test drive, no leaks, the water pump is so quiet. Victory!! This is a $1700 job at the dealership or $1200 at local shops. I saved my gf a lot of money there. The part actually has the "Toyota" engraving but it was scraped off or piled out. The same spot where the old one has it. Not sure why is that. I can tell this is an OEM part and AISIN is a part distributior. Thanks. ## Frequently Bought Together - AISIN WPT-803 New Engine Water Pump with Gaskets - Compatible with Select Lexus ES350, RX350, RX450h Toyota Camry, Highlander, RAV4, Sienna, Venza - AISIN THT-019 Engine Coolant Thermostat - Compatible with Select Lexus ES, HS, LS, RX, SC Scion tC, xB, xD Toyota 4Runner, Avalon, Camry, Corolla, Highlander, RAV4, Sienna, Tacoma, Tundra + More - Gates K070610 Micro-V Serpentine Drive Belt --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/12384217-aisin-genuine-wpt-803-new-engine-water-pump-with-gaskets](https://www.desertcart.sk/products/12384217-aisin-genuine-wpt-803-new-engine-water-pump-with-gaskets) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-09-24*
