If the coolant temperature is in the range from +92°to +97°C, the thermal switch turns on the fan. The fan is driven by an electric motor and rotates until the coolant temperature drops to +84°- +91°C.
Attention: The electric fan can also turn on when the ignition is off. Due to heat generation in the engine compartment, repeated switching on is possible.
Due to the fan not always running, the useful power of the engine is increased and fuel consumption is reduced.
Vehicles with air conditioning or trailer hitch are equipped with a second fan due to the greater cooling requirement of the engine. The second fan is driven by a V-belt from the first fan, so when the thermal switch is on, both of them work simultaneously.
Attention: If a trailer hitch is installed additionally, and in connection with this the load on the engine will increase, it is recommended to install a second fan at the same time.
