Warning: The radiator fan of the cooling system turns on depending on the engine coolant temperature and may sometimes turn on even when the engine is not running. Be especially careful when working near the fan blades to avoid injury from the rotating blades. As the coolant temperature drops, the fan turns off automatically. This is normal.
