MITSUBISHI FUSO CANTER FB300 FB308 FE100 FE111 FE211 ROSA BUS 4DR5 4DR50 4DR51 4DR7 2.7L 2.8L DIESEL ENGINE COOLING WATER PUMP ASSY (OE: ME996783 / ME996781 / ME996782 / ME996784 / ME996780 / A-3675 / A3675 / GWM-68A / WPM-041V / MADE IN JAPAN QUALITY)

Overview

The Mitsubishi Fuso Canter FB300 / 4DR5 Engine Water Pump Assembly (Water Pump Assy ME996783 / ME996781 / ME996784 / A-3675 / A3675 / GWM-68A) is a commercial-grade engine cooling system component engineered specifically for Mitsubishi Fuso Canter light commercial trucks, Rosa minibuses, and utility vehicles powered by Mitsubishi 4DR5, 4DR50, 4DR51 (2.7L), and 4DR7 (2.8L) 4-cylinder direct-injection diesel engines (Fuso Canter FB300, FB300A, FB308, FE100, FE111, FE211 commercial cargo lorries, wooden body trucks, tippers, box vans, and Rosa light buses). Manufactured to Japanese OEM standards, this water pump features a precision-machined pulley mounting flange hub, reinforced cast iron volute housing, precision multi-bolt perimeter mounting base, and high-efficiency cast internal impeller designed to deliver continuous, pressurized coolant circulation through the engine block, cylinder head, and radiator. Replacing a worn, noisy, bearing-seized, or leaking water pump restores optimal operating temperatures, preventing engine overheating, cylinder head warping, and blown head gaskets under continuous commercial haulage.

Key Dimensions & Specifications

• Top Pulley / Fan Mounting Hub: Pre-installed CNC-machined steel mounting flange featuring a multi-hole pattern and precision center pilot register collar for concentric pulley and fan clutch alignment.

• Rigid Cast Iron Volute Casing: Thick-walled cast iron housing with internal coolant flow runners and external structural reinforcement ribs designed to absorb continuous belt tension and high thermal stress.

• Precision Multi-Bolt Mounting Base: Multi-hole perimeter mounting flange base with a flat CNC-machined rear sealing surface for direct installation onto the engine timing gear housing / front block cavity.

• Bearing & Mechanical Shaft Seal: Industrial-grade high-capacity sealed roller/ball bearing cartridge paired with a wear-resistant silicon-carbide/carbon mechanical shaft seal to resist shaft play and coolant weepage under heavy load.

• Coolant Flow Impeller: Dynamically balanced high-efficiency cast internal impeller designed for continuous, high-volume coolant displacement across the 2.7L–2.8L 4-cylinder block and radiator.

• Please verify your existing water pump top flange diameter, pilot collar step, and mounting bolt pattern against your old sample pump before ordering.
