Nissens 85782 - Cooling Fan

A cooling fan is an electromechanical device that is used to cool an engine or other heat-producing device. The fan is typically mounted on the radiator, which is a heat exchanger that helps to cool the engine coolant. The fan blows air through the radiator, which helps to remove heat from the coolant.

There are two main types of cooling fans: electric fans and engine-driven fans. Electric fans are powered by the car's electrical system, while engine-driven fans are powered by the engine itself. Electric fans are more common on newer cars, while engine-driven fans are more common on older cars.

Electric fans are typically turned on by a thermostat, which is a device that senses the temperature of the engine coolant. When the coolant temperature reaches a certain point, the thermostat turns on the fan. The fan will continue to run until the coolant temperature drops below a certain point.

Engine-driven fans are turned on by the engine itself. The fan is connected to the engine by a belt, which turns the fan when the engine is running. The fan will continue to run as long as the engine is running.

Cooling fans are an important part of the car's cooling system. They help to keep the engine from overheating, which can cause serious damage to the engine. If the cooling fan is not working properly, the engine can overheat.

Here are some of the signs that your cooling fan may need to be replaced:

• The engine is overheating.
• The cooling fan is not turning on.
• The cooling fan is making a lot of noise.
• The cooling fan is visibly damaged.

If you notice any of these signs, it is important to have your cooling fan checked by a qualified mechanic.
