8-97601819-4 Cylinder Head Gasket 8976018194 Suitable for ISUZU FVR 6HK1

1. Quick Notice

Confirm the part number 8-97601819-4 or 8976018194 on your original cylinder head gasket before ordering. This gasket fits Isuzu 6HK1 engines installed in FVR, FTR, FXR trucks and various applications. Professional installation mandatory.

2. Description

The 8-97601819-4 cylinder head gasket is a precision sealing component for Isuzu 6HK1 diesel engines. This gasket seals the interface between the cylinder head and engine block, containing combustion pressure, coolant, and engine oil while preventing cross-contamination. This OE replacement part carries multiple cross-numbers including 8976018194, 8976018195, 8943927213, 332/F7696, 02/801789, 333/E3777, and 1876184380 [8†L5-L7]. The 6HK1 engine is a 6-cylinder, in-line diesel engine with 115 mm bore, 125 mm stroke, 7.8L (7,790 cc) displacement, and 17.5:1 compression ratio [13†L3-L5][14†L14-L16]. This engine is turbocharged with intercooler and common-rail fuel injection, producing 240 horsepower with peak torque of 706 N·m [14†L16][13†L6-L7]. Found in Isuzu FVR, FTR, FXR trucks (2004–2011), Hitachi excavators, and various heavy equipment [11†L37-L43]. The gasket is constructed from Multi-Layer Steel with elastomer coating, ensuring excellent durability and sealing performance across extreme thermal cycles [1†L10-L13]. Common failure symptoms include persistent engine overheating, coolant loss without external leaks, white exhaust smoke, milky oil, and exhaust bubbles in the radiator [0†L22-L24]. Replacement restores factory sealing integrity.

4. Custom Content

Surface Preparation: Both the cylinder head and engine block must be perfectly clean before installation. Remove all old gasket material using a plastic scraper. Do not use abrasive discs or wire brushes on sealing surfaces. The 6HK1 6-cylinder, in-line engine configuration requires careful attention to the single cylinder head covering all six cylinders.

Gasket Orientation: Install the cylinder head gasket with the printed side facing the cylinder head. The part number must be visible from the intake side. Some MLS gaskets require specific orientation — verify by comparing with the original gasket before removal [1†L23-L24].

Torque Sequence: Tighten cylinder head bolts in the specified sequence (center outward, spiral pattern) using progressive torque stages. Chase engine block threads with a thread tap before installation. Threads must be clean for accurate torque readings. Failure to follow proper torque specifications may prevent fasteners from reaching correct preload, leading to gasket failure [6†L9-L13].

Flattening Check: Maximum allowable cylinder head gasket surface flatness is 0.05 mm across 150 mm × 150 mm area. Measure before reassembly [1†L20]. MLS gaskets require a very smooth surface finish — typically 8 microinches Ra or less — to seal correctly [6†L43-L45].

Cooling System Refill: After installation, refill the cooling system with the correct coolant mixture. Bleed air from the system following manufacturer procedure. Inspect for leaks after the first heat cycle and retorque fasteners according to the 6HK1 service manual if specified.

5. FAQ (One by One Question and Answer)

Q1: What is the difference between 8-97601819-4 and 8976018194?
A1: These are the same cylinder head gasket. 8-97601819-4 is the Isuzu OEM numbering format with hyphens, while 8976018194 is the condensed form. Both reference the identical component.

Q2: What vehicles use the 8-97601819-4 cylinder head gasket?
A2: This gasket fits Isuzu FVR, FTR, and FXR trucks (2004–2011 model years) equipped with the 6HK1 engine [11†L37-L43], as well as Hitachi excavators (ZX330, ZX330-3, ZX350-3), Sumitomo SH300 excavators, and various heavy equipment powered by the 6HK1 engine.

Q3: Is this a Multi-Layer Steel (MLS) gasket?
A3: Yes. This gasket features MLS construction with multiple embossed stainless steel layers and elastomer coating for superior sealing performance across extreme temperature fluctuations [-40°C to +1200°C] [1†L10-L13].

Q4: What are typical symptoms of a failed cylinder head gasket on a 6HK1?
A4: Common symptoms include persistent engine overheating, coolant loss without external leaks, white exhaust smoke, milky oil (coolant mixing with oil), exhaust bubbles in the radiator overflow tank, and engine performance loss [0†L22-L24].

Q5: Do I need a new gasket every time I remove the cylinder head?
A5: Yes. The cylinder head gasket is a single-use sealing component. Always install a new gasket whenever the cylinder head is removed. Reusing an old gasket risks premature failure.

Q6: Does this gasket fit the 4HK1 engine?
A6: No. The 8-97601819-4 is specifically dimensioned for the 6HK1 6-cylinder engine. The 4HK1 4-cylinder engine requires a different cylinder head gasket.

Q7: Is sealant required for installation?
A7: No. MLS cylinder head gaskets are designed to seal without additional sealant. Install the gasket dry on clean, properly prepared surfaces. Do not apply any gasket sealant or RTV silicone to the gasket itself.

Q8: How do I properly store the gasket before installation?
A8: Keep the gasket in its original sealed packaging until ready for installation. Store flat at room temperature away from humidity, chemicals, and direct sunlight. Do not bend, crease, or stack heavy objects on the gasket.
