HINO SUPER DOLPHIN PROFIA LFS LSH SH FS FR FN FW K13C-TV K13C 12.9L OD 98MM 40MM 4-HOLE HUB ENGINE COOLING WATER PUMP ASSY WITH BACK PLATE (OE: 16100-3671 / 161003671 / 16100-3670 / 16100-3820 / HP-3115 / HP3115 / HWP-038 / HWP038)

Overview

The Hino Profia K13C-TV / K13C Pulley-Hub Type Engine Water Pump Assembly (Water Pump Assy 16100-3671 / 16100-3670 / 16100-3820 / HP-3115 / HWP-038) is a commercial-grade engine cooling system component engineered specifically for Hino Super Dolphin and Profia heavy commercial transport trucks and prime movers powered by Hino K13C-TV and K13C (12.9L / 12,882cc) inline-6 turbocharged diesel engines (Profia LFS, LSH, SH, FS, FR, FN, FW, and SS series heavy prime movers, cargo lorries, multi-axle tippers, dump trucks, and concrete mixers). Unlike the gear-driven K13C water pump variants, this K13C-TV configuration is built with a pre-installed 4-hole pulley/fan mounting flange hub (98mm outer diameter with a 40mm stepped pilot collar), a pre-assembled round rear cover plate (secured by 3 countersunk screws), an extended flanged side arm with dual 2-bolt oval ports, a machined metal hose outlet spout, and a 3-hole rear flange port. Replacing a worn, noisy, bearing-seized, or leaking water pump restores high-volume coolant circulation through the cylinder block and radiator under heavy commercial haulage.

• (Note: Hino K13C engines use two completely different drive mechanisms depending on the engine sub-code: K13C / K13C-TE models use shrouded timing-gear-driven water pumps [16100-3112 / HP-3111 or 16100-3320 / HP-3102], whereas K13C-TV models use this flanged pulley-hub water pump [16100-3671 / 16100-3670 / 16100-3820 / HP-3115 / HWP-038] with a 98mm / 40mm 4-hole top hub. Always check whether your old pump uses a 4-hole pulley hub or a drive gear prior to ordering.)
