The reason why the water tank is very hot but the fan doesn't turn
Whether the water temperature meets the requirements: At present, the fan of automobile radiator mostly uses electronic temperature control, so generally, the fan will start to rotate normally only when the water temperature in your car reaches the required temperature. If the temperature is too low, the radiator fan will not rotate. Therefore, when your car radiator fan does not turn, first check whether the water temperature meets the requirements.
Relay failure: If the water temperature meets the requirements and the radiator fan of the car still can't work, then there may be something wrong with the relay of the fan. If the relay fails, the cooling fan of the car will not work.
