At what temperature does the fan start to rotate?
1 Answers
When the water temperature reaches around 90 degrees, the fan starts to rotate. The fan is used for engine heat dissipation and coolant cooling to prevent engine failure caused by high temperatures. Reasons why the fan does not rotate: 1. The car's water temperature does not meet the standard: If the water temperature is too low, the radiator fan cannot rotate; 2. Relay failure: Poor contact in the relay circuit causes the fan not to rotate; 3. Thermostat switch failure: The fan operates with electronic temperature control. If the thermostat switch is damaged, the car's water temperature rises, and the cooling fan cannot receive power normally, resulting in the fan not rotating; 4. Fan failure: A broken fan control circuit or loose connectors can cause the fan to malfunction and not rotate.
