HINO DUTRO RANGER PRO TOYOTA DYNA XZU300 XZU340 XZU410 XZU420 J05C S05C S05D 4.6L 5.3L OD 80MM 40MM 16MM 4-HOLE HUB 10-HOLE BASE ENGINE COOLING WATER PUMP ASSY (OE: 16100-E0270 / 16100E0270 / 16100-E0271 / 16100-3730 / 16100-3731 / A-5877 / A5877)

Overview

The Hino Dutro / Ranger Pro / Toyota Dyna J05C S05C Engine Water Pump Assembly (Water Pump Assy 16100-E0270 / 16100E0270 / A-5877 / A5877) is a commercial-grade engine cooling system component engineered specifically for Hino Dutro, Ranger Pro, and Toyota Dyna commercial trucks powered by Hino / Toyota J05C (5.3L), S05C (4.6L), and S05D (4.9L) direct-injection diesel engines (Dutro XZU300, XZU302, XZU340, XZU410, XZU420, XZU430, and Dyna XZU series commercial cargo lorries, wooden body trucks, tippers, and box vans). Built with a pre-installed 4-hole threaded pulley/fan mounting flange hub (80mm outer diameter with a 40mm conical pilot collar and 16mm center pilot tip), a rigid ribbed cast iron volute housing, a 10-hole perimeter mounting base, a 2-bolt oval side flange port with an O-ring groove, dual front threaded ports, and a shrouded closed-face cast iron impeller configuration, this heavy-duty water pump delivers 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 and blown head gaskets under daily commercial transport workloads.

Key Dimensions (As Labeled in Product Photos)

• Top Pulley / Fan Hub Configuration: Pre-installed CNC-machined steel mounting flange featuring 4 threaded bolt holes, 80mm flange outer diameter, 40mm conical pilot register collar, and a 16mm center pilot tip.
