Fan Clutch Operation

They contain a drive and driven plate with annular grooves that fill with a thick viscous silicon fluid.

Rechargeable fan handheld. 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. We currently offer fan clutches for engines from 400 to 4000 horsepower which use cooling fans from 10 to 300 horsepower. Look carefully around the fan clutch for signs of oil leakage.

As temperatures increase the clutch engages so that the fan is driven by engine power and moves air to cool the engine. Our patented fan clutch is offered in various sizes. A fan clutch is attached to the front of an engine on rear wheel drive cars and trucks only.

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. These fans are needed at slow speeds typically below 35 mph and at idle. This allows the engine to operate more efficiently by removing the load that the fan places on it.

If it spins more than three full rotations this indicates that it may be prone to slipping. This important part of the cooling system is used to pull air though the radiator when the car is stopped or. The fan clutch is a cooling system component that controls the operation of the engine cooling fans.

Fluid coupling and thermostatic fan clutches are filled with silicone based oil. The fan clutch unit is approximately 1 foot tall by 1 foot wide. If the clutch or fan have excessive play remove the fan and clutch and check if the.

If the fan clutch requires repair take the vehicle to a qualified mechanic. Each fan clutch series number relates to its relative size within the product family. Then test the fan clutch by giving it a good push.

At a stop though because the fan clutch doesnt engage and air isnt forced through the radiator the engine cant dissipate excess heat. Viscous fan clutches are belt driven and found on many older rear wheel drive passenger cars.
