The design of new vehicles with smaller front grids and smaller space under the bonnet has reinforced the need to force air flow. The fan system provides an efficient air flow and optimizes the heat exchange to the radiator. It is usually located at the front of the vehicle, either in front or behind the radiator.
The fan system is made of: A support Its role is to fix the fan to the vehicle. On some vehicles, the support is also designed to improve the airflow (the shroud).
An Electric motor: The motor is specifically designed for each vehicle to avoid overconsumption. It is controlled by the thermoswitch, the pressure switch or the ECU. It frequently has two speeds (low or high).
A fan: If over-dimensioned, it may cause overconsumption causing a risk of fire. If under-dimensioned, performances are insufficient causing a risk of overheating or air-conditioning malfunction. A poorly-designed fan could also cause noise and generate vibrations which may lead to failure (motor or shroud).

In most cases, the fan system should be changed after a crash.
Other signals should also alert you to the necessity of a change:
- Vibration or noise may result from a broken support or damaged fan.
- Engine overheating (damaged fan or electric motor failure).
- The air-conditioning stops too frequently (the compressor automatically switches of in case of overpressure).
