HINO RANGER FC FD GD FT BUS BC144 W06D W06E W06C 5.8L 6.0L OD 80MM 45MM 4-HOLE HUB 7-HOLE BASE ENGINE COOLING WATER PUMP ASSY (OE: 16100-2531 / 161002531 / 16100-2530 / 16100-2532 / S1610-02531 / HP-3302)

Overview

The Hino Ranger W06D / W06E / W06C Engine Water Pump Assembly (Water Pump Assy 16100-2531 / 16100-2530 / 16100-2532 / HP-3302) is a commercial-grade engine cooling system component engineered specifically for Hino Ranger medium commercial transport trucks and buses powered by Hino W06D, W06E, and W06C (5.8L / 6.0L) inline-6 diesel engines (Ranger FC, FD, GD, FT series commercial cargo lorries, wooden body trucks, tippers, dump trucks, box vans, and BC144 buses). Built with a pre-installed 4-hole threaded pulley/fan mounting flange hub (OD 80M / 80mm outer diameter with 45M / 45mm pilot step), 7-hole mounting flange base, and 6-vane curved cast iron impeller configuration, this heavy-duty cast iron water pump delivers continuous, high-volume coolant circulation through the engine block and radiator to maintain stable operating temperatures under heavy commercial payloads. Replacing a worn, noisy, bearing-seized, or leaking water pump restores cooling efficiency and prevents engine overheating during daily fleet operations.

Key Dimensions (As Labeled in Product Photos)

• Top Pulley / Fan Hub Configuration: Pre-installed CNC-machined steel mounting flange featuring 4 threaded bolt holes, OD 80M (80mm) flange outer diameter, 45M (45mm) stepped pilot register diameter, and a precision protruding center pilot shaft.

• Mounting Base Configuration: 7-hole mounting flange base for direct installation onto the engine block / timing case.

• Housing Structure: Heavy-duty cast iron housing reinforced with external triangular support ribs around the sealed bearing neck.

• Impeller Design: Precision-cast 6-vane curved impeller on the rear cavity engineered for optimal coolant displacement.

• Measurement Notice: Key specifications including the OD 80M top hub diameter, 45M pilot step diameter, 4-hole threaded hub, 7-hole base pattern, and 6-vane impeller are shown directly in our product photos.

• Please verify your existing water pump top flange diameter (OD 80M), pilot step (45M), and 7-hole base pattern against the measurements shown in our photos before ordering.
