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.

Installation & Maintenance
⚠️ IMPORTANT: Water pump replacement on 4M50 engines requires moderate mechanical competence. Professional installation recommended for in‑experience DIYers.
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
Features & Benefits
| Feature | Benefit |
|---|
| Cast aluminum housing | Superior heat dissipation and structural integrity — resists warping and cracking under thermal stress |
| 7‑blade stamped metal impeller | Optimized coolant flow — delivers consistent flow across entire RPM range. Metal impeller outperforms composite alternatives |
| Precision sealing gasket included | Leak‑free installation — no additional gasket purchases required |
| IATF 16949 / ISO 9001:2008 certified | Consistent OEM-level quality — manufactured under strict automotive quality management systems |
| 100% factory leak‑tested | Reliable out of the box — each pump undergoes pressure testing at multiple RPM points |
Quality Control
| QC Item | Verification Method |
|---|
| Housing casting integrity | Pressure decay test — zero porosity allowed |
| Impeller balance / runout | Dynamic balancing at rated speed |
| Shaft seal leak integrity | Dry air pressurization to 1.5 bar — zero leakage for 60 seconds |
| Flow rate at multiple RPM points | Flow bench measurement at idle, rated speed, and max speed |
| Total functional test | Random 2-5% of each batch tested on full circulation loop for 2 hours |
