Water Pump ME994451 For Mitsubishi Fuso Canter 4M50 — Engine Coolant Pump 4.9L Diesel
ME994451 Water Pump for Mitsubishi Fuso Canter FE83D FE84D FG84D 4M50‑3AT7 4.9L Diesel — Engine Coolant Pump with Gasket
Product Overview
The Water Pump (Engine Coolant Pump) with OEM number ME994451 is a verified direct-fit replacement for Mitsubishi Fuso Canter light-duty trucks equipped with the 4M50 4.9L inline-4 turbo-diesel engine (engine variants: 4M50-3AT7, 4M50-5AT5). Compatible vehicle models include Fuso Canter FE83D (2008-), FE84D (2008-), FG84D (4x4 4WD, 2008-), FE85D (2008-2011), as well as FB_, FE_, FG_ series chassis with 4M50 engine. This water pump is also applicable to certain industrial equipment powered by the 4M50 engine, including Sany SY215C excavators.
The water pump is a critical component of the engine cooling system, mounted on the front of the engine block and driven by the accessory drive belt (serpentine belt) or timing gear system. It continuously circulates coolant through the engine block, cylinder head, and radiator to maintain optimal operating temperature and prevent overheating — especially critical for the 4M50 engine which operates under high thermal loads in commercial truck duty cycles.
This OE‑spec water pump features a high-strength cast aluminum housing, a 7-blade stamped metal impeller for superior coolant flow, and includes the OEM‑equivalent gasket/seal for a leak‑free installation.
Weight: 1.333 kg — precision-engineered for OE-spec fitment
Material: Cast aluminum housing / stamped metal impeller (7 blades)
Impeller type: 7‑blade stamped metal — optimized for high flow rates and corrosion resistance
Included: Pump assembly with gasket/seal

Common Failure Indicators
Coolant leak through weep hole — indicates internal shaft seal failure
Bearing wear / noise — grinding or rumbling noise from pump area
Impeller corrosion or erosion — reduces coolant flow
Gasket failure — external coolant leak at pump-to-block interface
Recommended Replacement Indicators
Coolant puddle under the vehicle (passenger/front side)
Low coolant level warning recurring despite topping up
Engine temperature gauge fluctuating or rising above normal
Grinding or squeaking noise from accessory drive area
Visible coolant residue or white crystalline deposits around water pump housing
Mileage exceeds 100,000 km with unknown pump service history
Maintenance Schedule: • Inspect water pump for external leaks at every 20,000 km oil change • Replace coolant every 2 years or 50,000 km • Preventive water pump replacement at 100,000 km recommended for commercial truck fleets
