HINO J08E J08ET KOBELCO EXCAVATOR SK300-8 SK330-8 SK350-8 SK350-9 SK360-8 7.7L 3-HOLE M6 THREADED HUB DIESEL ENGINE COOLING WATER PUMP ASSY WITH GASKET (OE: 16100-0070 / 16100-E0070 / 16100E0070 / 16100-4290)

Overview

The Hino J08E / Kobelco Excavator Water Pump Assembly (Water Pump Assy 16100-0070 / 16100-E0070 / 16100-4290) is a commercial-grade engine cooling system component engineered specifically for Kobelco heavy excavators, earthmoving equipment, and Hino commercial transport vehicles powered by Hino J08E (7.7L) 24-valve 6-cylinder turbocharged diesel engines (Kobelco SK300-8, SK330-8, SK350-8, SK350-9, SK360-8 hydraulic excavators, New Holland E385B, and Hino 500 series chassis equipped with belt-driven engine cooling systems). Built with the specialized 3-hole M6 threaded drive hub (3x M6 tapped bolt holes on pulley flange) configuration, this precision water pump delivers continuous, high-volume coolant circulation through the engine block, cylinder head, and oil cooler to prevent engine overheating, head gasket blowouts, and cylinder liner cavitation under sustained high-load digging, quarrying, and commercial operations. Replacing a worn, noisy, bearing-seized, or leaking water pump restores optimal engine operating temperature and safeguards your engine from catastrophic thermal breakdown.

Engineered to commercial fleet and heavy construction equipment specifications verified against Malaysian workshop standards for dependable replacement, cooling system overhaul, and preventive fleet maintenance.
