Wholesale Car Parts Fan Coupling 8-97128531-0 8971285310 For ISUZU 600P 4KH1 Diesel Truck

The Fan Coupling (OEM Numbers: 8-97128531-0 / 8971285310) is a premium-quality, direct replacement viscous fan clutch designed specifically for ISUZU 600P series trucks equipped with 4KH1 diesel engines.

This thermostatic fan coupling is mounted between the water pump pulley and the engine cooling fan. It uses a temperature-sensitive bimetal spring and internal silicone fluid to automatically engage or disengage the fan based on radiator air temperature, ensuring efficient cooling, faster warm-ups, and reduced fan noise.

• OE Quality: Manufactured to strict ISUZU dimensional and material specifications for perfect fit and function
• Thermostatic Control: Automatically engages and disengages the fan based on radiator air temperature
• Reduced Noise and Fuel Consumption: Fan freewheels when cooling is not needed
• Durable Construction: Precision aluminum housing and sealed bearing assembly withstand high temperatures
• Dynamic Balancing: Ensures smooth, vibration-free operation at all engine speeds
• Direct Replacement: Matches OE mounting flange, fan bolt pattern, and overall dimensions
• Long Service Life: Engineered for light-duty commercial truck applications
• Cost-Effective Repair: Affordable replacement that restores proper fan operation

This fan coupling is specifically designed for ISUZU light-duty trucks and commercial vehicles:

• ISUZU 600P (Light-Duty Trucks)
• ISUZU NQR, NPR, ELF series (as applicable with 4KH1 engine - verify with VIN)

• ISUZU 4KH1 - 3.0L Inline-4 Turbo Diesel
• Fuel Type: Diesel
• Application: Light-duty trucks and commercial vehicles

Professional mechanic installation recommended:

1. Ensure engine is cool - Never work on the cooling system when the engine is hot
2. Disconnect battery - Always disconnect the negative terminal before working
3. Remove the fan shroud to access the fan and coupling
4. Remove the fan blade assembly - Unbolt the fan blade from the fan coupling
5. Remove the fan coupling using appropriate tools
6. Inspect the water pump for play, noise, or leakage
7. Inspect the fan blade for cracks or damage
8. Clean mounting surfaces thoroughly
9. Install the new fan coupling on the water pump flange
10. Install mounting bolts to manufacturer torque specifications
11. Reinstall the fan blade and tighten bolts to specification
12. Reinstall the fan shroud and secure all fasteners
13. Reconnect battery terminal
14. Check fan operation and verify smooth rotation
15. Check for leaks in the coupling area
16. Road test to verify proper cooling system operation
