AISIN engine water pump WPH-054 for Acura & Honda — gasket + pulley, OEM-fit corrosion-resistant

AISIN WPH-054 is a complete aftermarket engine water pump with gasket and pulley designed to restore coolant circulation for select Acura and Honda engines.

Built by AISIN — a global OEM supplier — this new (not remanufactured) water pump uses carefully chosen materials and an advanced rotor and seal system to resist corrosion, scaling, and wear. The WPH-054 is engineered to replicate OEM fit and function while including a replacement gasket and pulley to simplify installation and reduce the need for additional parts.

How does the AISIN WPH-054 improve engine cooling compared to worn pumps?

The WPH-054 uses a smooth coolant flow path, precision-balanced rotor, and a carbon-ceramic mechanical seal to maintain steady flow and minimize leaks. Bearings and sealing surfaces are upgraded for longer service life under typical driving conditions.

• All-new components rather than remanufactured parts
• Carbon-ceramic seal for stronger leak resistance
• Ball bearings for quieter, stable operation
• Flow-optimized channels to reduce hotspots

Will this pump fit my vehicle and how do I confirm fitment?

The WPH-054 is compatible with a range of Acura and Honda models, but compatibility can vary by engine and year. Always confirm fitment using your vehicle’s VIN or the seller’s fitment checker before purchasing to ensure proper match.

• Compatible models: Acura TSX (2004–2008)
• Compatible models: Honda Accord (2003–2007)
• Compatible models: Honda CR-V (2007–2009) and Element (2003–2011)
• Verify specific engine and VIN with the fitment tool

What hardware and features come with the water pump package?

The unit ships as a complete kit including the water pump assembly, a replacement gasket, and the pulley to match factory mounting. Providing these parts together helps speed up installation and reduce the risk of reuse-related leaks or failures.

• Water pump assembly — new, not remanufactured
• Matching gasket included for sealed installation
• Pulley included to mirror OEM drive alignment
• Materials chosen to resist rust and coolant deposits

How long should I expect this AISIN water pump to last?

Service life depends on driving conditions, maintenance, and coolant quality, but AISIN’s manufacturing standards and improved sealing typically extend longevity over worn or low-quality replacements. Routine cooling system care and correct coolant mixture are essential to achieve the best lifespan.

• Durable materials to reduce corrosion and scaling
• Precision seals to limit leaks over time
• Ball bearings to reduce premature wear
• Recommended: flush cooling system and replace coolant as specified

Who is this for? The AISIN WPH-054 water pump with gasket is intended for owners and technicians seeking a reliable, OEM-grade replacement for affected Acura TSX and Honda Accord, CR-V, and Element models. It’s a good choice if you want a new, full-assembly pump with matching gasket and pulley to restore proper coolant flow and reduce the chance of rework or additional parts purchases. Confirm fitment for your specific model and engine before ordering to ensure a correct, hassle-free installation.
