8-97386772-0 8973867720 Oil Pan and Level Gauge Assembly for ISUZU 700P Engine Oil Pan

The Oil Pan and Level Gauge Assembly (OEM Numbers: 8-97386772-0 / 8973867720) is a premium-quality, direct replacement engine component designed specifically for ISUZU 700P series trucks equipped with 4HK1, 4HF1, 4HG1, and 4HE1T diesel engines (2008 onwards). This complete assembly includes the oil pan (oil sump) and the oil level gauge (dipstick), providing both the oil reservoir and a reliable means of checking engine oil level.

The oil pan stores and circulates engine oil, allowing it to drain back from the engine after lubrication and providing a steady supply to the oil pump. The oil level gauge enables the driver or technician to accurately monitor oil level for safe engine operation.

• OE Quality: Manufactured to strict ISUZU dimensional and material specifications for perfect fit and function.
• Complete Assembly: Includes both oil pan and oil level gauge (dipstick) for a comprehensive replacement.
• High-Strength Construction: Durable steel or cast aluminum alloy withstands vibration, thermal cycling, and mechanical stress.
• Precision-Formed Sealing Surface: Machined mating flange ensures a leak-proof seal with the engine block and oil pan gasket.
• Proper Oil Capacity: Designed to hold the correct volume of engine oil for reliable lubrication and cooling.
• Accurate Oil Level Gauge: Durable dipstick with precise markings allows reliable oil level monitoring.
• Drain Plug Provision: Includes standard drain plug opening for easy oil changes.
• Restores Oil Containment: Eliminates oil leaks caused by a cracked, bent, or rusted oil pan.
• Direct Replacement: Matches OE pan dimensions, mounting bolt pattern, and oil pickup clearance.
• Long Service Life: Engineered for medium-duty commercial truck applications.
• Essential Engine Component: Critical for maintaining proper oil circulation, lubrication, and engine protection.

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 — Remove the drain plug and drain the engine oil into a suitable container.
4. Remove the old oil pan — Unbolt and remove the old oil pan; carefully separate it from the engine block.
5. Remove the old gasket — Peel off the old oil pan 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 the engine block — Check for warpage, cracks, or damage on the block mating surface.
8. Install the new gasket — Position the new oil pan gasket on the engine block; ensure proper alignment with bolt holes.
9. Install the new oil pan — Carefully position the new oil pan on 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. Install the drain plug — Install the drain plug with a new washer if applicable; tighten to specification.
12. Install the oil level gauge — Insert the new dipstick into the guide tube; ensure it seats fully and the handle is secure.
13. Refill with engine oil — Fill with the correct grade and quantity of engine oil.
14. Check oil level — Use the new oil level gauge to verify proper oil level.
15. Check for leaks — Start the engine and inspect the oil pan joint and drain plug for oil leakage.
16. Road test — Test drive to verify proper sealing and no oil leaks.
