Thermostat with housing, seal and temperature switch suitable for Citroën, DS, MINI, Peugeot. A combustion engine must operate within a certain temperature window in order to function optimally. The temperature is controlled by a coolant and a thermostat. The thermostat ensures that the engine reaches its ideal operating temperature as quickly as possible and then maintains it continuously. A defective or blocked thermostat can cause the engine to overheat. This is why febi only offers coolant thermostats in OE matching quality. Quality management tests the offered thermostats for different requirements and loads, including function, accuracy of fit, dimensional accuracy, and material quality. febi mainly offers thermostats with housings in which the seal and the temperature sensor are already integrated.
