The Honda 90103-YE5-003 Bolt-Washer (8X25) is a genuine OEM fastener designed for WP20 and WP30 water pumps. As a direct Honda OEM component, this part is built to the same specification as the hardware originally installed at the factory. Honda supersedes fastener part numbers at serial breaks, so confirm part number 90103-YE5-003 against your pump's serial number in the fitment table before ordering.
Key Features
- Genuine Honda OEM Hardware — sourced directly from Honda, this bolt-washer meets the exact dimensional and retention requirements of the original part it replaces.
- Integrated Washer Design — the captured washer distributes clamping load evenly, eliminating the need to source a separate washer during reassembly.
- Confirmed WP20 and WP30 Fitment — listed for Honda WP20 and WP30 water pumps; verify your serial number against the fitment table to ensure this is the correct part for your unit.
A bolt-washer combines a threaded bolt with a permanently attached washer, allowing a single fastener to both clamp and spread load across the mating surface in one step. On Honda water pumps, keeping the correct fasteners in place ensures that pump housings, covers, and other components are held securely under the vibration and pressure conditions the pump encounters during operation. A missing or incorrect fastener can allow components to work loose, leading to leaks or accelerated wear at the joint.
