Isuzu 1-11282018-0 Oil Cooler Core Assembly

This oil cooler core assembly is engineered to OEM specifications for Isuzu 6BG1, 6BD1, 6BG1T, and 6BD1T diesel engines. It functions as the primary heat exchanger for engine lubricating oil, maintaining optimal oil viscosity and preventing thermal degradation under heavy-duty operating cycles. Constructed with aluminum plate-fin core technology, the unit provides high thermal transfer efficiency in a compact form factor. It features direct-flange mounting interfaces compatible with the OEM engine block and oil filter housing assembly. The core is designed to withstand continuous operating pressures typical of Isuzu 6-cylinder diesel lubrication systems. Primary applications include Hitachi EX200, EX200-2, EX200-3, EX200-5, and EX200K hydraulic excavators. Cross-compatibility extends to Kato HD220-5 and Doosan DH220-5 excavators utilizing the Isuzu 6BD1T or Doosan DB58 engine platforms. Replaces Isuzu part numbers 1112820180, 111282-0180, and 1112810261.
