Product Description
Product Introduction 1308010LE399 Fan Clutch is an electronically controlled silicone viscous coupling dedicated for HFCN721 engine cooling fan system. It adjusts fan rotation speed intelligently according to coolant temperature signal, engaging and disengaging flexibly to regulate cooling airflow. This aftermarket replacement clutch eliminates continuous high fan noise, excessive fuel consumption and engine overheating risks caused by internal silicone leakage, temperature sensor failure and damping fatigue of old units. Precise speed control maintains stable working temperature for the engine and cuts unnecessary power loss for JAC light trucks that frequently run urban delivery routes with variable load.
Product Advantages High-precision internal temperature sensing module responds quickly to coolant temperature changes. Sealed cavity structure prevents silicone oil leakage under vibration and thermal cycling. Optimized heat dissipation ribs suppress overheating of the clutch itself. Every fan clutch undergoes temperature response and slip testing before shipment, OEM mounting dimensions support direct replacement without extra modification.
