OE quality viscous fan clutch electric fan clutches Supply

Short Description:

Fan clutch is a thermostatic engine cooling fan that can freewheel at low temperatures when cooling is not needed, allowing the engine to warm up faster, relieving unnecessary load on the engine. As temperatures increase, the clutch engages so that the fan is driven by engine power and moves air to cool the engine.

When the engine is cool or even at normal operating temperature, the fan clutch partially disengages the engine’s mechanically driven radiator cooling fan, generally located at the front of the water pump and driven by a belt and pulley connected to the engine’s crankshaft. This saves power, since the engine does not have to fully drive the fan.

However, if engine temperature rises above the clutch's engagement temperature setting, the fan becomes fully engaged, thus drawing a higher volume of ambient air through the vehicle's radiator, which in turn serves to maintain or lower the engine coolant temperature to an acceptable level.

The fan clutch can be driven by a belt and pulley or directly by the engine when mounted on the engine’s crankshaft.There are two types of fan clutches:viscous fan clutch(Silicone oil fan clutch) and electric fan clutch.Most fan clutches are silicone oil fan clutch on the market.

Silicone oil fan clutch, with silicone oil as a medium,utilizing the high viscosity characteristics of silicone oil to transmit torque. The temperature of the air behind the radiator is used to automatically control the separation and engagement of the fan clutch through the temperature sensor. When the temperature is low, the silicone oil does not flow, the fan clutch is separated, the fan speed is slowed down, basically idling. When the temperature is high, the viscosity of the silicone oil makes the fan clutch combine to drive the fan blades to work together to regulate the temperature of the engine.
