The Oil Cooler Core with OEM reference numbers 8-97334101-0 and 8-97028739-0 (also 8973341010 and 8970287390) is a verified direct-fit replacement for the ISUZU NKR and NPR series trucks equipped with the 4HF1 engine. This core is a critical component of the engine's lubriion system, designed to cool the engine oil by transferring heat to the engine coolant or surrounding air.
The oil cooler is a compact, multi-plate heat exchanger that prevents the engine oil from exceeding its optimal thermal operating range. By maintaining proper oil temperature, it ensures the oil maintains its viscosity, provides adequate lubriion, and prevents oxidation and deterioration. A failing or clogged oil cooler core can lead to engine overheating, increased oil consumption, and premature engine wear.
This OE‑spec replacement core is manufactured to exact OEM specifiions regarding plate count, flow path geometry, and heat exchange surface area. It restores proper oil cooling and protects your engine from heat-related damage.
