Injection Nozzle Assembly 8-97603415-8 8976034158 For ISUZU CXZ 6WF1 Engine

The Injection Nozzle Assembly (OEM Numbers: 8-97603415-8 / 8976034158) is a premium-quality, direct replacement fuel injection component designed specifically for ISUZU CXZ series heavy-duty trucks equipped with 6WF1 diesel engines. This precision-engineered nozzle assembly atomizes diesel fuel into a fine mist and injects it into the combustion chamber at the exact moment and pressure required for optimal combustion.

• OE Quality: Manufactured to strict ISUZU dimensional and flow specifications for perfect fit and function
• Precision Atomization: Exact orifice geometry ensures fine fuel mist for efficient combustion
• Durable Construction: High-grade alloy steel body and needle withstand extreme pressures and temperatures
• Calibrated Performance: Each nozzle tested to ensure correct opening pressure and flow rate
• Restores Engine Power: Eliminates rough running, misfire, and power loss caused by worn nozzles
• Improves Fuel Efficiency: Proper atomization leads to complete combustion and reduced fuel consumption
• Reduces Emissions: Efficient burning minimizes black smoke and harmful exhaust emissions
• Direct Replacement: Matches OE nozzle dimensions, threads, and sealing configuration
• Long Service Life: Engineered for heavy-duty commercial diesel engine applications
• Essential for Fuel System Overhaul: Recommended replacement during injector service or engine rebuild

Professional diesel mechanic or injection specialist installation is essential:

1. Ensure engine is cool - Allow the engine to cool completely before working on the fuel system
2. Disconnect battery - Always disconnect the negative terminal before working on electrical components
3. Relieve fuel pressure - Follow manufacturer procedure to relieve pressure in the fuel system
4. Remove the injector - Disconnect fuel lines and electrical connectors; remove the injector from the cylinder head
5. Disassemble the injector - Separate the nozzle assembly from the injector body using proper tools
6. Clean all components - Thoroughly clean the injector body and nozzle seating area; remove carbon and debris
7. Install new nozzle assembly - Position the new nozzle on the injector body with a new copper washer
8. Torque nozzle retaining nut - Tighten to manufacturer torque specifications
9. Reinstall the injector - Install the injector into the cylinder head with new seals; torque to specification
10. Reconnect fuel lines - Reconnect high-pressure fuel lines and electrical connectors
11. Prime the fuel system - Operate the hand primer or crank the engine to prime the fuel system
12. Start and test - Start the engine; check for smooth idle, proper power, and no leaks
13. Check for leaks - Inspect all fuel connections for leakage
14. Road test - Test drive to verify proper engine performance and fuel economy

• Flow Rate Testing: Each nozzle tested to ensure proper fuel flow and spray pattern
