Fan Clutch Work

As temperatures increase the clutch engages so that the fan is driven by engine power and moves air to cool the engine.

Electric fan description. This clutch is positioned at the hub of the fan in the airflow coming through the radiator. Most fan clutches are filled with a silicone based oil. A fan clutch is a temperature controlled coupling between the water pump shaft and the fan which allows the fan to be operational at low speeds and disconnected at higher speeds.

This is when the fan clutch does not work properly and thereby decreasing the car air conditioners performance as the fan clutch also cools the condenser of the air conditioning unit. Learn what makes a viscous fan clutch operate. This type of clutch is a lot like the viscous coupling sometimes found in all wheel drive cars.

The most common problem encountered with a fan clutch is when the car overheats while it is not running. Then test the fan clutch by giving it a good push. How does it work.

Most cars that have an engine driven cooling fan have a thermostatically controlled viscous clutch the temperature of the fluid actually drives the clutch. A 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. A properly functioning fan clutch is critical to engine reliability as it works to maintain a safe temperature range.

This allows the engine to operate more efficiently by removing the load that the fan places on it. To engage the fan internal valves open and allow the fluid to fill the working area of the clutch. A fan clutch is attached to the front of an engine on rear wheel drive cars and trucks only.

The engine cooling fan made of plastic or metal isnt hard connected to the fan pulley or water pump but instead is soft connected via the fan clutch. A fan clutch is used as an integral part of your engines cooling system. Detailed animations show internal components.

Before you replace it you may wonder how does a fan clutch work. If it spins more than three full rotations this indicates that it may be prone to slipping. Bolted to the water pump between the water pump pulley and flange the clutch fan turns at engine speed and is driven by the serpentine belt.

The fan clutch unit is approximately 1 foot tall by 1 foot wide. This creates friction between the drive plate and the housing causing the fan to spin. This important part of the cooling.

No matter if you have a kysor horton or any brand fan clutch it may come a time when you have to replace your fan clutch. If the fan clutch requires repair take the vehicle to a qualified mechanic. How does a fan clutch work.

The oil is held in an internal reservoir when the fan is disengaged.
