Why do front wheel drive cars have electric fans?

Why do front wheel drive cars have electric fans?

Front-wheel drive cars have electric fans because the engine is usually mounted transversely, meaning the output of the engine points toward the side of the car.

Can electric fans can be mounted in front or behind the radiator?

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. A puller fan on the other hand sits right behind the radiator.

How much HP does electric fan add?

So essentially the electric fans take 1/2 horsepower. The mechanical to electrical conversion in the alternator to drive the electric fan is not 100% efficient, so the engine will have to make slightly more power to provide the electric fan the same horsepower.

Front-wheel drive cars have electric fans because the engine is usually mounted transversely, meaning the output of the engine points toward the side of the car. The fans are controlled either with a thermostatic switch or by the engine computer, and they turn on when the temperature of the coolant goes above a set point.

How does the cooling system work on a rear wheel drive car?

The fans are controlled either with a thermostatic switch or by the engine computer, and they turn on when the temperature of the coolant goes above a set point. They turn back off when the temperature drops below that point. Rear-wheel drive cars with longitudinal engines usually have engine-driven cooling fans.

How do you fit a fan to a radiator?

Hold the fan in place and fit a fibre washer between one of the fan brackets and the radiator face. Fit a cone-shaped spring to a plastic mount, then pass the mount through the bracket and washer, then on through the radiator fins.

How do you fit an electric fan to a car?

Fitting an electric fan to a car. The Pacet electric cooling fan is available in two sizes; which you need depends on the size of your engine. The smaller fan (A) comes ready assembled with the motor in its support bracket. The larger fan (B), has first to be assembled, using support brackets (C) and motor (D).

Where are the electric fans on a radiator?

Electric radiator fans are available in both pusher and puller designs. Pusher-style fans mount on the front of the radiator and blow air through the radiator core. Puller-style fans mount behind the radiator and draw air through the core. Puller-style fans are recommended for applications in which the electric fan is the primary cooling source.

How does a front wheel drive car fan work?

Newer vehicles, especially cars that are front-wheel drive, generally use an electric fan. When the coolant temperature goes up and reaches a certain point, the fan will turn on through a mechanism controlled by a thermostat or engine computer. Once the temperature drops far enough, it turns off.

Can a pusher fan be used behind a radiator?

Puller-style fans mount behind the radiator and draw air through the core. Puller-style fans are recommended for applications in which the electric fan is the primary cooling source. A pusher-style fan can be used as an auxiliary cooling source, but you should sure make the fan covers as much of the radiator core as possible.

How many CFM does an electric radiator fan need?

Summit Racing carries a huge selection of electric radiator fans to complete your cooling system upgrade. Cooling fans are categorized by cubic feet per minute (cfm) ratings. A general guideline to follow for cooling a stock engine is 2,500 cfm for an 8-cylinder, 2,000 cfm for a 6-cylinder, and 1,250 cfm for a 4-cylinder.
