The CALORSTAT by Vernet TS2920 is a critical component for maintaining your vehicle's engine temperature. It functions as a thermostat, controlling the flow of coolant to the radiator. When the engine reaches its optimal operating temperature, the thermostat opens, allowing coolant to circulate and be cooled. This part also integrates the function of the radiator fan switch. When the coolant temperature rises above a specific threshold, this switch activates the radiator fan, providing additional cooling to prevent overheating. This dual functionality ensures your engine operates efficiently and avoids potential damage from excessive heat. Designed for reliability and precise temperature control, the TS2920 from CALORSTAT by Vernet is built to meet stringent quality standards. Proper functioning of this component is essential for engine longevity and performance, especially under demanding driving conditions or in hot climates.
