The Honda 90101-YE6-003 Bolt-Washer (10X25) is a genuine OEM fastener designed for WP20 and WP30 water pumps. Sourced directly from Honda, this part carries the exact specifications Honda engineers designed into these pumps from the factory. It is listed for both the WP20 and WP30 — confirm your model and serial number against the fitment table to ensure this is the correct part for your unit.
Key Features
- Genuine Honda OEM — manufactured to Honda's own specifications, ensuring the correct thread pitch, shank diameter, and integrated washer bearing surface for the WP20 and WP30.
- Integrated Washer Design — the combined bolt and washer construction distributes clamping load evenly, maintaining consistent retention without a separate loose washer to track during service.
- Serial Number Verification Advised — Honda supersedes fasteners at production breaks, so check your pump's serial number against the fitment table before ordering to confirm part number 90101-YE6-003 applies to your unit.
A bolt-washer is a fastener that combines a hex bolt and a captive washer into a single piece. On the WP20 and WP30 water pumps, fasteners like this one secure pump housings, covers, and structural components, keeping the assembly tight under the vibration and load of pump operation. When a fastener stretches, strips, or is lost during service, replacing it with the correct OEM specification piece ensures proper clamping force is restored and the pump operates as intended.
