• 【What is a Fan Clutch】: The Fan Clutch is an important part of your cooling system. Its drive shaft attaches to the water pump. Then, the fan attaches to the clutch housing.The fan clutch’s job is to control when the fan comes on and off. It provides airflow when needed. It also reduces drag on the engine when not needed. This improves power and fuel economy.
• 【How does it work】: Most fan clutches are filled with a silicone-based oil. The oil is held in an internal reservoir when the fan is disengaged. To engage the fan, internal valves open and allow the fluid to fill the working area of the clutch. This creates friction between the drive plate and the housing, causing the fan to spin. To disengage the fan, the valves close. The fluid is kept in the reservoir. This reduces the friction and allows the housing and fan to spin independently of the shaft.
