Product Description
Oil Cooler Core 8-97334101-0 / 8-97028739-0 for ISUZU NKR NPR 4HF1 — OEM Engine Oil Cooler Core
8-97334101-0 8970287390 Oil Cooler Core for ISUZU NKR NPR 4HF1 4HG1 -- OEM Replacement
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 lubrication 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 lubrication, 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 specifications regarding plate count, flow path geometry, and heat exchange surface area. It restores proper oil cooling and protects your engine from heat-related damage.

Common Failure Symptoms
| Symptom | Description |
|---|---|
| Engine overheating | Temperature gauge rising above normal due to inadequate oil cooling |
| Low oil pressure | Oil thins out at high temperatures, reducing pressure |
| Increased oil consumption | Oil degrades faster due to excessive heat |
| Oil leaks | Visible oil around the cooler core or housing |
| Decreased engine performance | Loss of power under load |
| Black smoke from exhaust | Inefficient combustion due to poor lubrication |
⚠️ Ignoring a failing oil cooler core can lead to:
- Severe engine damage from overheating
- Premature wear on bearings, camshafts, and turbochargers
- Oil sludge formation and clogged oil passages
- Costly engine repairs or complete engine replacement
