Electric Engine Fan

Engine fans are a component in a vehicle, which counter overheating of the engine,with the use of cool air. The main engine fan is mounted in between your engine and the radiator which helps produce the best air flow to cool the engine. In most trucks, SUV’s, and RWD vehicles, a mechanical fan is used and driven by the belt accessory components which are mounted facing the radiator. The engine fan is especially important at lower speeds to keep constant air flow to their radiator, therefore cooling the coolant that is then returned to the engine block. At highway speeds the engine fan is not as needed because the airflow hitting the front of the radiator as it travels down the road is enough to cool down the coolant.

Electric cooling fans are a great option for an engine cooling fan because it will free up horsepower and better control the engine tempeture. Electric fans are also very useful when dealing with situations where the clearance in the engine compartment is a problem. An electric cooling fan comes in two options a puller and a pusher. A puller fan is best used as the primary cooling option, it pulls the air in through the radiator when placed behind the radiator. A pusher fan is best used for auxiliary purposes as it is pulling air from behind the fan and sending the air in the direction the fan is positioned. Compared to electric fans, engine mounted fans are inefficient because an engine mounted fan pulls less air when the engine is idling or at lower RPM’s and creates more drag which can reduce engine power and fuel economy.

Electric Fan Motors

The purpose of the electric fan motor is to covert electrical energy into mechanical energy which spins the fan blade. If your electric fan motor goes out you will not be able to cool the engine at idle or slow speeds which can cause the engine to overheat leading to many expensive problems. Electrical fan motors are classified by the source of electrical power used to operate, in an automobile the power is DC meaning direct current. Continue Reading--->

Fan Spacers

Fan spacers are an important part of any fan that is not positioned correctly or needs the blade readjusted into the appropriate position. When it comes to the engine fan in a vehicle, it is best that the fan blades are ¾” to 1” from the surface of the radiator. Keeping the fan positioned in this particular spot is needed for the cooling of the engine and the best airflow in the engine compartment. Continue Reading -->

Flex Fans

Flex fans are flexible fan blades on a fan that change shapes depending on the RPM the vehicle is at. Flex fan blades are a lighter and more flexible and are made out of aluminum or stainless steel. They are made from these materials so that the blades can change shape when the fan starts spinning at higher RPM’s. Normal vehicle fans are a heavy and sturdy blade that is constantly spinning at the same speed so long as the engine is on. Continue Reading -->

Fan Clutch

Many vehicles with a fan attached to the motor also have a fan clutch. This clutch is used to disengage the fan at a particular engine RPM. The clutch does this because at higher engine RPM’s, enough air is flowing over the radiator that a fan is not needed. And once the vehicles engine RPM goes down again, the fan is re-engaged.
