The clutch fan is equipped with a fan clutch between the pulley and the fan blade hub, and the working state of the fan can be adjusted through the separation and engagement of the clutch. This not only ensures the normal operating temperature of the engine, but also reduces the power loss of the engine and reduces fuel consumption. Common clutch fans include electromagnetic clutch fans and silicone oil clutch fans.

Electromagnetic fan clutch, when the coolant temperature reaches the specified value, the coolant temperature sensor switch or the air temperature sensor switch automatically turns on the circuit, and the clutch coil is energized to form a closed magnetic circuit to generate magnetic pulling force, so that the armature and the pulley are engaged, and the fan works; when cooling After the liquid temperature drops, the sensor switch is disconnected, the armature is quickly reset under the action of the diaphragm spring, the clutch is separated, and the fan stops working.

The silicone oil clutch fan is closed when the engine temperature is high, and the fan works to reduce the temperature of the radiator; when the engine temperature is low, the fan clutch automatically disengages and the fan does not rotate, saving engine power and increasing the cooling water temperature.

The rotation of the fan does not indicate whether the fan clutch is malfunctioning, because whether it is malfunctioning or a normal fan clutch is in a disengaged state, it will follow the water pump pulley to rotate. You can judge whether the fan clutch is normal by listening to the sound of the fan. When the water temperature of the normal fan clutch is higher than 86℃, the fan will make a normal working sound, while the malfunctioning fan clutch will make a much lower sound. When the fan clutch fails, the fan does not rotate when the engine water temperature is high. At this time, when the engine is turned off, loosen the nut and insert the locking plate into the pin hole of the driving shaft to fix the fan and the driving shaft. , Do not use the fan clutch to force the fan to rotate; wait for an opportunity to repair the fan clutch, and then restore the automatic clutch function of the fan clutch.
