The radiator fan thermal switch on all vehicles is mounted at the bottom of the radiator. The thermal switch is two-stage and turns on the electric fan with a rotation speed corresponding to the temperature of the coolant. On vehicles with diesel engines, two electric radiator fans are installed, and with gasoline engines, one (see illustration 8.0).
