Chevy Radiator Fan Clutch

A car’s engine needs to operate in the most efficient temperature to ensure its long life and good working condition. To do this, the excess heat should be removed from the engine to get the engine up to the correct temperature as soon as possible after starting. This whole process is being taken cared of by the cooling system, enabling the engine to perform at the most efficient temperature no matter what the operating conditions are.

Further, the radiator also needs a fan which would provide enough air to help the engine cool off. This fan has several blades, normally made of plastic, and is mounted between the radiator and the engine for the purpose of letting outside air to enter into the radiator easily. Some vehicles are equipped with additional fan placed right in front of the radiator for faster cooling of the engine because since the vehicles move slowly during hot season, only limited amount of cool air are attracted into the radiator resulting to the engine’s poor cooling.

To further reinforce the radiator fan, a fan clutch is often outfitted to it. Fan clutches like the Chevrolet fan clutch is a small fluid coupling with a thermostatic device which controls a variable speed fan. Its main function is to ensure that the fan will rotate at moderate speed to keep the engine from possible overheating. It is also designed to minimize drive to the fan when the said fan is no longer used or needed.

A fan clutch has a fluid coupling partly filled with silicone oil to be used solely for that purpose. The fan clutch regulates the heat alerts a bimental coil spring to uncoil or expand for that matter in case the air temperature passing through the radiator rises because as it expands, only a little more oil is allowed to enter the fluid coupling thus triggering the fan to rotate. On the other hand, if it is a cool air that will enter the radiator, the oil instead contracts leaving the fluid coupling and the fan is slowed down, consequently reducing fuel consumption, minimizing noise and saves engine power. The fan clutch is a very important component of the cooling. Immediate replacement of which is essential when you think that it is no longer functioning well.
