What is the reason why the bright fan of automobile engine can't refuel at high speed?

1. The reason why the fan of the automobile engine runs wildly is that the engine temperature is too high, or the engine cannot enter the degraded mode due to other driving reasons.

2. Most likely, due to the high water temperature, the fan rotates at high speed. Check the circulation of the cooling system and then check the thermostat. You should clean the throttle first, then use software to clear the fault light and check the fault code. If it is not the fault of the engine itself, clearing the fault code should be able to recover.

3. If the thermostat is not faulty, the problem will be serious. It's best to let the 4S shop tow the car away for maintenance, which can't be solved personally.
