The Cylinder Head Gasket with OEM numbers 8976018190 / 8-97601819-0 is a verified direct-fit replacement for ISUZU 6HK1 7.8L diesel engines. This gasket is installed between the cylinder block and cylinder head, serving as a critical component of the combustion chamber sealing system, widely used in ISUZU FVR/CXZ/LT series heavy-duty trucks and Hitachi ZX360-3/ZX330/ZX350 large excavators.
The cylinder head gasket is installed between the engine block and cylinder head, withstanding extreme temperatures (combustion temperatures can exceed 2000Β°C) and pressures (cylinder pressures up to 150β200bar). Its core function is to ensure absolute sealing of the combustion chamber's high-temperature, high-pressure gases, preventing power loss from gas leakage, while simultaneously sealing oil galleries and coolant passages between the block and head to prevent cross-contamination or external leakage. This product features a Multi-Layer Steel (MLS) construction, composed of multiple layers of stainless steel with a sealing coating, capable of maintaining reliable sealing performance through repeated thermal expansion and contraction cycles.
Replace immediately if any occur:
- Loss of Power β Poor acceleration; difficulty climbing hills (compression loss reducing combustion efficiency)
- Abnormal Coolant Consumption β Coolant level drops consistently with no visible external leak (coolant entering combustion chamber)
- White Smoke from Exhaust β Persistent white smoke during start-up or operation (coolant vaporizing in combustion chamber)
- Milky/Thickened Engine Oil β White foam on dipstick or oil filler cap (coolant mixing with oil)
- Engine Overheating β Temperature gauge reads high consistently (combustion gases leaking into cooling system, causing air pockets)
- Hard Starting β Insufficient cylinder compression making starting difficult
- Fuel in Cooling System β Oil film or diesel odor in expansion tank (high-pressure gases breaching gasket into cooling system)
- Installation Success Rate: 98.5% direct fitment rate β confirmed across 112 repair orders (Jan 2024 β Jun 2025)
- Material: Multi-Layer Steel (MLS) β multi-layer stainless steel composite with sealing coating
- Operating Temperature: Withstands combustion chamber temperatures exceeding 2000Β°C and -40Β°C cold starts β extreme temperature tolerance
- Sealing Pressure: Withstands 150β200bar cylinder pressure β ensures absolute combustion chamber sealing
- Design Features: Fire Ring combustion seal + integrated coolant/oil passage seals β multi-layer sealing architecture
- Direct OEM Interchange: Direct replacement for ISUZU original parts β OE number 8976018190 / 8-97601819-0
- Brand Cross-Reference: IZUMI equivalent specification β internationally recognized brand
- Associated OE Numbers: 8976018191 / 8-97601819-1; 8976018195 / 8-97601819-5

Important Notes:
- The cylinder head gasket is a critical component of the combustion chamber sealing system β failure leads to compression loss, power reduction, and potentially catastrophic engine damage
- Recommended to replace cylinder head bolts simultaneously (must use new bolts)
- Must be installed with correct torque and sequence as specified in the workshop manual in stages (must use torque wrench)
- Cylinder head and block sealing surfaces must be thoroughly cleaned and inspected for warping or scoring
- For 100% accurate fitment, please provide VIN (Chassis Number) or engine model
