The thermoswitch is an essential component in the cooling system of heavy duty and truck vehicles. It plays a critical role in regulating the engine temperature by turning the electric fan on and off as needed. This helps prevent the engine from overheating, which can cause severe damage. It is crucial to regularly maintain and inspect the thermoswitch to avoid costly repairs in the future.

In some cases, thermo-switches have two levels of fan activation, depending on the temperature. The second level causes the fan to operate at a higher speed, providing additional cooling power.

Due to its function, the thermoswitch is often located close to the radiator to sense the temperature of the coolant and respond accordingly. Calorstat by Vernet offers a wide range of thermoswitches designed to meet or exceed OEM specifications, ensuring reliable performance and safety for your heavy duty or truck vehicle.
