Why Does the Engine Overheat and the Fan Not Rotate?
1 Answers
Engine overheating with the fan not rotating can be attributed to the following reasons: Insufficient engine coolant temperature: Most modern vehicle radiator fans operate based on electronic temperature control. Therefore, the fan typically only starts rotating when the engine coolant reaches the required temperature. If the temperature is too low, the radiator fan will not rotate. Relay malfunction: If the coolant temperature meets the requirements but the vehicle radiator fan still does not operate, the issue might lie with the fan relay. A faulty relay can prevent the radiator fan from functioning. Thermostat switch issues: Certain faults in the thermostat switch can also impact the operation of the vehicle radiator fan, so it is important to inspect this component as well.
