The radiator fan forces air to flow through the radiator and decrease the temperature of the coolant while the car is stationary (e.g. in a traffic jam). A broken fan should be replaced as soon as possible. Otherwise, the engine will not be cooled properly and may fail. A malfunctioning fan may fall apart, damaging the radiator and other devices. The fan replacement procedure depends on how the fan is powered and accessed. In some cars it is necessary to remove the headlamps, the front bumper or the radiator cover.
