AISIN Engine Water Pump WPT-804 with Gaskets for Lexus LX570 & Toyota V8 — OE-quality, Ceramic Seal

AISIN WPT-804 is a brand-new, OE-quality engine cooling water pump with gaskets designed to restore reliable coolant circulation for select Lexus LX570 and Toyota V8 models.

This pump is manufactured by AISIN, a leading original equipment supplier with decades of automotive engineering experience. Built from all-new components, the WPT-804 emphasizes durable materials, precision machining, and design features aimed at resisting rust, corrosion, and coolant scale. It ships with the necessary gasket(s) for replacement and is intended to match or exceed factory standards for fit and function when paired with the correct engine variant.

How does the AISIN WPT-804 improve cooling system reliability?

The WPT-804 uses a smooth-flow impeller and precision bearings to maintain consistent coolant circulation and minimize turbulence that can reduce thermal efficiency. Carbon ceramic mechanical sealing helps prevent leaks and prolongs service life compared with lower-quality seals. Together, these design choices maintain performance under varying operating conditions.

• Efficient impeller geometry for steady coolant flow
• Carbon ceramic mechanical seal to reduce leaks
• Durable ball bearings for long-lasting rotation
• Materials selected to resist rust, corrosion, and scaling

Will this water pump fit my Lexus or Toyota?

The WPT-804 lists compatibility with specific Lexus and Toyota V8 models, but engine sub-variants can affect fitment. Always confirm compatibility with your vehicle’s year, model, and engine code using the seller fit checker or your VIN before purchasing. The included gasket(s) are matched for the listed applications.

• Compatible models: Lexus LX570 (2008–2011, 2013–2021)
• Toyota compatibility: Land Cruiser (2008–2011, 2013–2021), Sequoia (2008–2022), Tundra (2007–2021)
• Verify engine variant and VIN-based fitment to avoid returns
• Gaskets included to support a proper seal on the listed vehicles

What materials and features help this pump last longer?

AISIN selects construction materials specifically to withstand common water pump failure causes like corrosion and coolant deposits. The combination of upgraded alloys, precise machining, and a high-quality mechanical seal reduces wear and leak risks. Because the unit is new rather than remanufactured, internal tolerances and finishes are controlled to factory-level specifications.

• All-new components—not remanufactured—ensure fresh tolerances
• Corrosion-resistant materials minimize premature degradation
• Smooth coolant passages reduce scaling and deposit buildup
• High-grade bearings and seals improve longevity

What comes in the box and what should I prepare for installation?

The package includes the AISIN WPT-804 water pump and the required gasket(s) to complete the replacement. Basic mechanical skills and common hand tools are typically sufficient for installation, but depending on vehicle layout you may need to remove accessories or engine covers. Follow a service manual or professional installer guidance for torque specs and coolant bleeding procedures.

• Included: AISIN WPT-804 water pump plus gasket(s)
• Recommended: service manual or OEM torque values for fasteners
• Prepare new coolant and follow proper system-bleeding steps
• Inspect drive belts, pulleys, and thermostat while replacing pump

Who is this for? The AISIN WPT-804 is aimed at owners and mechanics replacing a failing or worn water pump on compatible Lexus LX570 or Toyota Land Cruiser, Sequoia, and Tundra models who want an OE-level, all-new component with sealed bearings and upgraded materials. It suits DIYers comfortable with engine cooling system work, independent shops seeking reliable replacement parts, and anyone prioritizing longevity and corrosion resistance in their cooling system repair.
