This electronically controlled silicone oil fan clutch belongs to the engine cooling system, it automatically controls fan rotation speed according to engine water temperature to adjust heat dissipation. It reduces engine load and fuel consumption when the temperature is low, and quickly increases fan speed to lower temperature when overheating occurs. The product adopts high-quality silicone oil and precise electronic induction module, with excellent heat dissipation and stable response performance. The aluminum alloy shell has good heat dissipation and vibration resistance to adapt to long-distance heavy transport. Every fan clutch passes strict performance and sealing tests before delivery. It can solve abnormal temperature, fan stuck and other common faults, which is an important replacement part for engine cooling system maintenance.
