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