Oil Pan Gasket 8-97364386-0 8-97146148-2 8-97190191-1 For ISUZU NKR NPR 4HK1 4HG1 4HF1

The Oil Pan Gasket (OEM Numbers: 8-97364386-0 / 8-97146148-2 / 8-97190191-1 / 8973643860 / 8971461482 / 8971901911) is a premium-quality, direct replacement engine sealing component designed specifically for ISUZU NKR and NPR series trucks equipped with 4HK1, 4HG1, and 4HF1 diesel engines. This precision-engineered gasket is installed between the engine block and the oil pan, creating a reliable, leak-free seal that retains engine oil in the crankcase while preventing dust, moisture, and road contaminants from entering. Proper sealing is critical for maintaining correct oil levels, preventing oil loss, and ensuring reliable engine lubrication and cooling.

Function: The oil pan gasket seals the joint between the engine block and oil pan, preventing engine oil leakage and keeping dust and contaminants out of the lubrication system in ISUZU NKR and NPR diesel engines.

• OE Quality: Manufactured to strict ISUZU dimensional and material specifications for perfect fit and function.
• High-Quality Sealing Material: Oil-resistant composite fiber, rubber-coated metal, or rubber resists hot oil, heat, and vibration.
• Precision Die-Cut: Exact dimensions ensure correct fitment around all bolt holes and oil pan contours.
• Leak-Proof Performance: Prevents oil seepage from the engine block and oil pan joint.
• Restores Engine Cleanliness: Eliminates oil accumulation on the engine and surrounding components.
• Direct Replacement: Matches OE gasket dimensions and sealing configuration.
• Long Service Life: Engineered for commercial diesel engine applications.
• Essential for Engine Service: Critical component to replace whenever the oil pan is removed.
• Cost-Effective Repair: Affordable replacement that prevents oil loss and engine contamination.
• Reliable Sealing: Maintains proper oil retention for efficient engine lubrication.

Professional mechanic installation recommended:

1. Ensure engine is cool — Allow the engine to cool completely before disassembly.
2. Disconnect battery — Always disconnect the negative terminal before working.
3. Drain engine oil — Drain the engine oil into a suitable container.
4. Remove the oil pan — Unbolt and remove the oil pan to access the old gasket.
5. Remove the old gasket — Carefully peel off the old gasket; note its orientation.
6. Clean all mating surfaces — Thoroughly clean the engine block and oil pan surfaces; remove all old gasket material, oil, and debris.
7. Inspect surfaces — Check for warpage, cracks, or damage on both mating surfaces; repair or replace if necessary.
8. Install the new gasket — Position the new oil pan gasket on the engine block or oil pan; ensure proper alignment with bolt holes.
9. Reinstall the oil pan — Carefully place the oil pan over the gasket; hand-start all bolts.
10. Torque bolts — Tighten bolts in a criss-cross pattern to manufacturer torque specifications. Do not over-tighten.
11. Refill with engine oil — Fill with the correct grade and quantity of engine oil.
12. Check for leaks — Start the engine and inspect the oil pan joint for oil leakage.
13. Road test — Test drive to verify proper sealing and no oil leaks.
