The Honda 78101-YF2-505 Casing is a genuine OEM replacement built for the WX15 water pump. As a direct Honda OEM component, this casing is manufactured to the same standards as the original, ensuring a proper fit and correct internal geometry for the pump. This part is designed specifically for the WX15, so verify your unit's serial number against the fitment table before ordering.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this casing matches the original part in every dimension, ensuring the pump's internal flow path is restored exactly as designed.
- Correct Fit for the WX15 — engineered specifically for the WX15 water pump, this casing installs as a direct replacement with no modification needed to connect to existing pump components.
- Pump Performance Restored — a damaged or cracked casing causes pressure loss and reduced flow output; replacing it with this genuine part brings the pump back to its rated delivery capacity.
- Serial Number Verification Recommended — Honda updates parts at production breaks, so cross-check your WX15 serial number against the fitment table to confirm this casing is correct for your unit.
The casing is the outer housing that forms the primary fluid chamber of the WX15 water pump, enclosing the impeller and directing water flow from the inlet through to the discharge outlet. It must maintain a precise internal profile to sustain proper pumping pressure and flow rate — any cracking, erosion, or damage to the casing disrupts this flow path and causes the pump to lose output or prime. Replacing a worn or damaged casing with a genuine Honda part restores the pump's ability to move water at its intended volume and pressure.
