FAQ

Q: How do I verify this water pump fits my Hino engine?
A: Check your existing water pump part number (stamped on the housing). It should match 16100-3801 or 16100-3632. Also confirm your engine model (EL100, EC100, or M10C) and pulley tooth count (22). If unsure, send us a photo of your old pump for verification.

Q: What is the installation procedure for this water pump?
A: Drain coolant, remove fan and belt, unbolt old water pump, clean gasket surfaces, apply new gasket (included), install new pump with torque specs (typically 25-30 Nm), refill coolant, and bleed air. We recommend replacing the thermostat and coolant simultaneously.

Q: How often should I replace the water pump on my Hino excavator?
A: Typical replacement interval is every 2,000-3,000 operating hours or as part of major engine overhaul. Signs of failure include coolant leaks, bearing noise, overheating, or visible shaft play. Regular inspection during coolant changes is advised.
