The radiator necessitates a fan that would spin speedily to give enough air for cooling the engine. This fan features four or more blades and is usually mounted between the radiator and the engine in order for the outside air to easily find its way to the radiator. To draw more cool air, some vehicles are outfitted with an additional fan positioned in front of the radiator. This extra fan is aimed particularly during hot season or when the vehicle isn’t moving fast enough. On these situations, very small amount of cool air gets in the radiator; hence, the engine isn’t cooled properly.

For it to be more efficient, radiator fan is outfitted with a fan clutch. It is a small fluid mixture with a thermostatic apparatus and is designed to be in command of a variable-speed fan. Fan clutch makes sure that the fan will run or spin at the proper speed to prevent the engine from overheating as well as to decrease drive to the fan when it is no longer needed. The fan clutch possesses a fluid mixture that’s partly made up of silicone oil that’s intended for that sole purpose. When the temperature of the air that passes through the radiator gets higher, the heart commands a bimetal coil spring to uncoil or expand. As it expands, it lets a little more oil to come into the fluid coupling before it will start to run or rotate the fan.

The opposite happens if the air that comes through the radiator is cool. Instead of expanding, the coil spring contracts, the oil departs from the fluid coupling and consequently, the operation of the fan goes slow. Slowing the fan when it isn’t needed lessens fuel consumption, produces less noise and drastically saves engine power. In some cases, a flat bimetal strip is employed instead of a coil spring. This kind of bimetal strip tends to bow out and in as the temperature drops and rises to allow oil from going in and out of the said fluid coupling.
