SINOTRUK HOWO TRUCK WEICHAI ENGINE WP10 WP12 WD615 ENGINE Fan Blade / Fan Assembly 612600060123
Product Features
1. Forced-Air Cooling: High-speed rotation generates powerful axial airflow, forcing cool air through the radiator and intercooler to rapidly dissipate engine heat and prevent overheating.
2. Circular Directed Airflow: A unique integrated outer ring design contains the airflow to prevent leakage, significantly improving intake efficiency and suppressing high-speed vibration.
3. Power Enhancement: Effectively cools high-temperature air from the turbocharger, increasing oxygen content in the intake charge for more complete combustion and unleashing the engine's full horsepower.
4. Lightweight, Noise-Reducing, and Fuel-Efficient: Constructed from high-strength reinforced plastic, the unit is lightweight with low rotational inertia; this minimizes parasitic power loss (improving fuel economy) and significantly reduces wind noise.
Common Issues and Replacement Recommendations
1. Embrittlement and Fracture: Heavy-duty trucks often operate under harsh thermal cycling conditions, causing plastic fan blades to age and become brittle. Damaged or broken blades severely disrupt dynamic balance during high-speed rotation, causing violent engine vibration; detached blades can even puncture the radiator fins.
2. Comprehensive Inspection Recommended: When replacing fan blades, it is strongly recommended to manually check the fan bracket and the viscous clutch bearing for looseness or abnormal noise. If clutch failure causes the fan to run continuously or not at all, the clutch should be replaced along with the fan blades.
