Temperature Switch, radiator fan - TS2904 CALORSTAT by Vernet

The power unit of the car will quickly fail with significant overheating. A sensitive rCALORSTAT by Vernet brand Temperature Switch, radiator fan instantly reacts to an increase in temperature to a critical limit. Because of the signal, the fan turns on, rapidly cooling the radiator.

The radiator temperature switch is a device responsible for the operation of the electric fan included in the cooling system of the power unit. The device is designed to turn on the electric fan at a certain temperature, which provides airflow to the radiator, heat removal from the motor.

The principle of the temperature switch work

The radiator cooling fan in the vehicle is activated when the coolant temperature reaches dangerously high levels. The device is activated precisely thanks to the fan switch, which monitors the temperature change.

This device helps to avoid overheating of the engine, as well as overhaul, which may be required in the event of a breakdown of the vehicle's engine. If the forced removal of heat from the radiator does not occur, it is possible that the reason is a faulty radiator temperature switch.
