MITSUBISHI FUSO FIGHTER FM515 FK515 FM215 FK115 6D14 6D14-2AT 6D15 6D15-T 6.6L 6.9L TURBO DIESEL ENGINE COOLING WATER PUMP ASSY (OE: ME035247 / ME035245 / ME035246 / ME996931 / ME075049 / A-3659 / A3659 / FWP-027 / MADE IN JAPAN QUALITY)

Overview

The Mitsubishi Fuso Fighter FM515 / FK515 6D14-2AT Engine Water Pump Assembly (Water Pump Assy ME035247 / ME035245 / ME996931 / ME075049 / A-3659 / A3659 / FWP-027) is a commercial-grade engine cooling system component engineered specifically for Mitsubishi Fuso Fighter FM and FK series medium-to-heavy commercial transport trucks and tippers powered by Mitsubishi 6D14, 6D14-2AT (6.6L Turbocharged), and 6D15 / 6D15-T (6.9L Turbocharged) 6-cylinder direct-injection diesel engines (Fuso Fighter FM515, FK515, FM215, FK115 commercial cargo lorries, wooden body trucks, tippers, dump trucks, and box vans). Manufactured to Japanese OEM standards, this heavy-duty water pump features a precision-machined pulley mounting flange hub, reinforced cast iron volute housing, multi-bolt perimeter mounting base, and high-flow cast internal impeller designed to deliver continuous, pressurized coolant circulation through the cylinder block, cylinder head, and engine oil cooler. Replacing a worn, noisy, bearing-seized, or leaking water pump restores optimal operating temperatures, preventing severe 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 6.6L–6.9L turbocharged 6-cylinder block and oil cooler.

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

Always check your chassis plate [FM515] and engine type [6D14-2AT] prior to ordering.)

Why Choose Our Commercial Truck Parts?

• High-Volume Turbocharged Coolant Flow: Dynamically balanced internal impeller delivers continuous, high-volume coolant circulation across the cylinder block, cylinder head, and oil cooler, preventing localized hot spots under sustained turbo boost and heavy loads.

• Precision CNC-Machined Pulley Flange Hub: High-strength steel mounting flange ensures concentric fan and pulley alignment, eliminating belt runout, vibration, and premature belt wear.

• Heavy-Duty Sealed Bearing & Mechanical Seal: High-capacity bearing cartridge paired with a wear-resistant silicon-carbide/carbon shaft seal withstands continuous radial belt tension and cooling system pressures without developing shaft play or weeping.

• Rigid Cast Iron Volute Housing: Thick-walled iron casting resists thermal fatigue, engine vibration, and cracking during heavy commercial operation.

• Ready Stock & Fast Shipping: Readily stocked for quick dispatch.
