Detailed Description

Dayco DP904 is an engine water pump built for vehicles that use a timing belt to drive the pump. Fitment includes 2022-2026 Acura MDX, 2021-2026 Honda Odyssey, 2021-2026 Honda Passport, 2021-2025 Honda Ridgeline, and 2021-2024 Honda Pilot, along with earlier timing belt driven Acura and Honda applications such as MDX, RLX, TLX, TL, TSX, Accord, Crosstour, and Accord Crosstour. It also covers 2004-2007 Saturn Vue. For fitment-based searches, this is a Dayco DP904 water pump for Honda Odyssey water pump replacement and Acura MDX cooling system service.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Is Used For

Replacing a leaking or worn engine water pump
Restoring coolant circulation in timing belt driven engines
Addressing overheating caused by pump wear or seal failure
Supporting scheduled timing belt and water pump service together
Serving as a replacement water pump for Acura and Honda V6 platforms

Installation Notes and Tips

Review the vehicle-specific fitment before ordering, since this pump is used across multiple engine and model combinations. The fitment notes state that the timing belt should be replaced with the water pump, so plan the service accordingly on Acura MDX, Honda Pilot, Honda Odyssey, and other listed applications. Confirm the exact model year and engine configuration against the vehicle VIN and service information before installation.

Quality Assurance

Dayco supplies aftermarket engine cooling components for timing belt driven applications, and the DP904 is cataloged for direct replacement use on the listed vehicles.

This part fits 173 vehicles

Always verify fitment with your vehicle's VIN if unsure. Submodel & trim restrictions may apply.
