Understanding Your Radiator Cooling Fan

Automobiles need cooling fans to carry heat away from the engine in the same way that people need fans and air conditioners to keep us from melting in the summer. It's difficult for human beings to stay cool when the weather is warm unless we have a machine to help us.

And, in the same way we become lazy and tired when we get overheated, your car's engine responds exactly the same.  In fact that is true of most engine-powered machines.  Just like we can pass out and eventually die from overheating, your car can too.  So maintaining your car's cooling system helps to extend the life of your vehicle.

What is a radiator-cooling fan and what do they do?

Radiator cooling fans:


• Are heat exchangers that in conjunction with your radiator, keep your car's engine from burning-out and seizing.


• Are specifically designed to keep your car's engine running at a cooler temperature, which ensures the engine's longevity.


• Have 4 to 6 blades that rotate at high speeds to bathe your car's engine with adequate amounts of cool air.


• Are located between the radiator and the engine so heat is dispersed away from the engine.


• Are efficiently designed so that they turn on when the engine temperature rises and turns off when the engine temperature returns to normal.


• Sometimes are controlled by a thermostat switch.

With today's high-tech engines, there are a number of different kinds of radiator cooling fans available and choosing the right one can sometimes be confusing, at best. When shopping for a replacement cooling fan, follow your manufacturer's recommendation to be certain the cooling fan meets your vehicle's requirements. Do not purchase a cooling fan based on price alone - quality is critical to maintaining your vehicle's level of performance and to extend the life of your car's engine.
