It is serious if the car fan keeps running. Detailed reasons and solutions for the car fan continuously running: The car fan keeps running even when the water temperature is normal because the thermostat is damaged or the sensor function is not installed. The sensor detects the engine water temperature, and the fan starts when the temperature rises. If it fails, the fan keeps running regardless of the water temperature. The advantage is that the water temperature won't get too high in summer, but the disadvantage is that there will be no warm air in winter. Solutions: Normally, when the water temperature reaches a certain level, the thermostat opens, allowing the radiator water to circulate. The fan will only start when the engine temperature reaches a certain level, detected by the sensor. In colder weather, the fan rarely activates while driving. If you suspect an issue, you can test it by revving the engine to under 2500 RPM while stationary. Typically, the fan should start within about 10 minutes under normal conditions. If the car has a thermostat installed and the water temperature is not too high or the engine does not overheat, there should be no major issues. It is best to visit a service station for a check-up and use a diagnostic tool to measure the water temperature. To prevent radiator corrosion, always use high-quality, long-lasting antifreeze from reputable manufacturers that meets national standards.
