Are electric radiator fans better?
Are electric radiator fans better?
An electric fan completely removes the mechanical load of spinning the fan from the engine. It places an additional draw on the electrical system, but this is a more efficient means of spinning a fan, and it has a smaller impact on engine drag.
What does an electric fan do in a car?
The radiator fan (or fans) pulls cooling air through the car’s radiator. Positioned between the radiator and engine, cooling fans are particularly helpful when the car is stationary or moving at speeds too slow to force air through the grille.
What size electric fan do I need?
Determine Optimum Airflow As a general rule of thumb, follow these minimum cubic feet per minute (cfm) ratings when using an electric fan as the primary cooling source on a basic engine: 1,250 cfm for a 4-cylinder. 2,000 cfm for a 6-cylinder. 2,500 cfm for a 8-cylinder.
How much horsepower does electric fans add?
In a normal pickup situation, even in high ambient temperatures, the electric fan system will only draw a maximum of about 5 horsepower from the engine. This significant savings improves fuel economy, and, in turn, reduces emissions while improving vehicle performance.
How do you know if the fan in your car is bad?
The first symptom or sign that something has gone wrong is that your cooling fan doesn’t come on at all. This is the most common symptom of a faulty cooling fan motor, but it may not be one you notice while driving your vehicle. If the motor burned out or starts to fail in any way, the cooling fans are disabled.
Do I need a puller or pusher electric fan?
Electrical fans can either push air through the radiator or pull air through it. A pusher fan sits in front of the radiator. When a vehicle is moving, a pusher fan can obstruct airflow due to its positioning in front of the radiator. Always choose a puller fan but if space is an issue then use a pusher fan.
