Ford Focus fan not activating, potential thermostat issue on Ford Focus

Some Ford Focus owners report experiencing issues with the radiator fan not activating, which may be attributed to a faulty thermostat. These owners often find that checking the coolant level and inspecting the fuse is a necessary first step. A defective thermostat can prevent the engine from reaching the correct temperature, ultimately leading to the radiator fan not engaging at the appropriate time. Additionally, if the fan fails to turn on, it may cause the engine to overheat, potentially linked to a malfunctioning temperature sensor. Furthermore, the electric radiator fan's components, such as the electric motor and fan blades, may require servicing or replacement due to their limited lifespan. It is crucial for owners to ensure the thermostat is functioning properly to maintain the cooling system's efficiency and prevent overheating issues.
