Cooling Fan Belt 8-97315153-0 8973151530 For ISUZU NKR77 4JH1 Engine Truck Parts

The Cooling Fan Belt (OEM Numbers: 8-97315153-0 / 8973151530) is a premium-quality, direct replacement drive belt designed specifically for ISUZU NKR77 series light-duty trucks equipped with 4JH1 diesel engines. This essential accessory drive belt transmits rotational power from the engine crankshaft pulley to the cooling fan and water pump, ensuring proper coolant circulation and airflow through the radiator to maintain optimal engine operating temperature.

• OE Quality: Manufactured to strict ISUZU dimensional and material specifications for perfect fit and function
• Durable EPDM Construction: High-quality rubber compound resists heat, oil, ozone, and weathering for long service life
• Polyester Reinforcement: High-strength cords provide superior tensile strength and resistance to stretching
• Precision-Molded Profile: Ensures optimal grip on pulleys, reducing slippage and belt squeal
• Consistent Power Transfer: Reliable drive ensures proper cooling fan and water pump operation at all engine speeds
• Prevents Overheating: Maintains proper coolant circulation and airflow to prevent engine overheating
• Reduces Noise: Precision profile minimizes belt squeal and vibration
• Direct Replacement: Matches OE belt dimensions - no modification required
• Cost-Effective Maintenance: Affordable component that protects the engine cooling system
• Easy Installation: Simple belt replacement with basic hand tools

This cooling fan belt is specifically designed for ISUZU light-duty trucks and commercial vehicles. Common applications include:

• ISUZU NKR77 (Light-Duty Trucks)
• ISUZU 4JH1 Engine Specifications:
  • 4-Cylinder, Inline Diesel
  • Displacement: 3.0L
  • Valvetrain: OHV
• Also compatible with various ISUZU models using the 4JH1 engine with the same accessory drive configuration

Professional mechanic or DIY installation recommended:

1. Ensure engine is cool - Never work on engine accessories when the engine is hot
2. Locate the cooling fan belt - Identify the belt on the front of the engine; refer to the belt routing diagram (if available)
3. Release belt tension - Loosen the cooling fan/alternator mounting bolts (if equipped with tensioner) or the idler pulley to release tension
4. Remove the old belt - Slip the old belt off the pulleys; inspect for wear, cracks, or glazing
5. Inspect pulleys - Check cooling fan, water pump, crankshaft, and idler pulleys for damage, wear, or misalignment
6. Clean pulley grooves - Clean debris or rubber buildup from pulley grooves
7. Install the new belt - Route the new belt around all pulleys according to the routing diagram
8. Apply tension - Move the tensioner or alternator to apply proper belt tension
9. Tighten mounting bolts - Hold tension and tighten mounting bolts to specification
10. Check belt tension - Press on the belt at the midpoint of the longest span; deflection should be within manufacturer specification (typically 10-15 mm with moderate thumb pressure)
11. Re-check tension after run-in - After running the engine briefly, re-check and adjust tension if necessary
12. Test operation - Start the engine; listen for belt squeal; verify cooling fan and water pump operation
13. Check for proper cooling - Ensure engine temperature remains within normal range
