ISUZU FORWARD F-SERIES MEDIUM TRUCK FSR FRR FTR FSS FTS SBR JCR 6BD1 6BD1T 6BG1 6BB1 5.8L 6.5L ENGINE COOLING WATER PUMP ASSY WITH GASKET (OE: 1-13650-016-0 / 1-13650-016-1 / 1136500160 / 1136500161)

Overview

The Isuzu Forward FSR / FRR 6BD1 6BG1 Engine Water Pump Assembly (Water Pump Assy 1-13650-016-0 / 1-13650-016-1 / 1136500160) is a commercial-grade engine cooling system component engineered specifically for Isuzu Forward F-Series medium commercial transport trucks (中卡) powered by Isuzu 6BD1 (5.8L), 6BD1-T turbo, 6BG1 (6.5L), and 6BB1 (5.4L) inline-6 diesel engines (FSR, FRR, FTR, FSS, FTS, SBR, SCR, and JCR series medium cargo lorries, wooden body trucks, tippers, dump trucks, box vans, and industrial machinery like Hitachi EX200 series excavators). Built with a precision-balanced impeller, heavy-duty mechanical shaft seal, high-grade bearing assembly, and standard mounting hub, this water pump delivers continuous, high-volume coolant circulation through the engine block and radiator to prevent engine overheating, cylinder head warping, and cavitation under sustained commercial payloads. Replacing a worn, noisy, bearing-seized, or leaking water pump prevents catastrophic engine overheating and restores consistent operating temperatures.

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