Temperature-Sensitive Viscous Fan Clutch Unit DZ62066060001 High Toughness Plastic Fan Blade Assembly For Heavy-Duty Truck Heat Dissipation

Product Description

This DZ62066060001 silicone viscous fan clutch assembly is a key temperature-controlled cooling component for heavy-duty diesel engines. It combines a multi-blade high-strength nylon cooling fan and a thermal-sensitive silicone viscous clutch hub as one complete unit. Relying on thermal sensing bimetal strips, the clutch automatically adjusts fan rotation speed by controlling silicone fluid flow based on engine coolant temperature: speeding up for strong heat dissipation at high temperatures and slowing down to cut power consumption and noise when the engine is cool. The fan blades are integrally injection molded with reinforced nylon to deliver large air volume while resisting cracking and deformation. All central mounting hole sizes and hub spline specifications match original engine standards for direct bolt-on replacement without extra modification during cooling system maintenance.

Key Product Advantages

• Intelligent temperature automatic regulation design reduces engine load and fuel consumption, effectively lowering running noise during cold start and cruising.
• Reinforced PA nylon fan blades with hollow lightweight structure produce powerful airflow for efficient radiator and intercooler heat dissipation.
• Precision silicone viscous clutch with sealed internal fluid chamber prevents silicone oil leakage and maintains stable speed regulation performance for long service life.
• Uniformly distributed multi-bolt fastening structure firmly locks fan blades to the metal hub, avoiding blade loosening or falling off under high-speed rotation.
• Complete factory pre-assembled finished unit eliminates separate matching of fan and clutch, greatly improving repair and replacement efficiency for service shops.
