Search for Radiator fan :

Each car is equipped with a radiator fan, designed to improve the cooling fluids circulation. It is achieved by increasing the quantity and speed of air passing directly through the radiator. The fan is usually installed between the radiator and the engine in a special box. The radiator fan connects four or more blades, located on a common pulley. In order to increase the airflow, the blades are arranged at a certain angle to the plane of rotation.

Radiator fans have different types of drive: mechanical, electrical, and hydromechanical. The most common is considered the electrical radiator fan drive. The drive turns on the motor and the control system. The electrical motor is powered from the onboard network of any vehicle. The control system coordinates the fan performance depending on engine temperature.

Usually the electrical devices are not demountable. Despite the fact that theoretically the part can be repaired, to restore it is quite expensive and not very reasonable. The only way out is to buy new parts. Many cars have a manageable fan overrun control function, which means that the fan will be switched off right after the engine stops. Fan overrun control function is meant for a better cooling of the vehicle`s engine depending on its mode of operation before stopping.

Inoperative radiator cooling fan is considered the main cause of engine overheating and of it`s failure. So, it is very important to change this part with the signs of malfunction. Currently, the most reasonable way to purchase car spare parts is the Internet. So if it is time to replace the radiator fan that is compatible with any car, welcome to our online shop. Only here you can find all the necessary parts for your car - from central lock and flywheel to spoiler and bumper.

What you need to know about a cooling fan replacement: lifetime limits, common defects and their signs, tips and recommendations

A cooling fan has no certain lifetime limit. This device also cools an air conditioner condenser, and it often fails to work because of electromotor or activation sensor breakdown. In case several elements of the cooling fan are out of order, for example after a road accident, a new component is needed.

When a car radiator fan is defective, the coolant temperature gets higher. Corresponding indicator on the dashboard shows this.

In order to check this component you need to start the engine and let it work at idle. A serviceable cooling fan is activated when the coolant temperature is nearing the critical value. In this case you’ll hear a characteristic noise from under the bonnet. If not, then the component is defective.

You should address to specialists for comprehensive diagnostics. It is recommended to replace the radiator fan at a service station because non-qualified actions at its installation increase the risk of engine overheating.
