While your car’s radiator is usually able to dissipate heat from the engine into the current of cool air passing through the grille, sometimes this isn't possible - particularly in hot weather or while stuck in traffic. If the engine temperature becomes too high, thermostatic switches or computer controlled electronic sensors trigger the car fan to spin and force air through the radiator, which in turn helps to keep your engine cool. If your car fan is damaged or non-responsive, there is nothing preventing your engine from overheating, which can have serious consequences. We stock high quality replacement car fans compatible with every make and model of car so your engine stays cool, whatever the weather.
