Abstract
A work vehicle includes an engine, a compressor used to compress an air toward the engine, a charge air cooler, a sensor, and a control unit. The charge air cooler comprising or coupled to a fan. The fan can rotate in a first direction to remove a heat of the air and to rotate in a second direction reverse to the first direction so as to blow a debris. The control unit is electrically coupled to the engine and to the fan. The control unit predicts whether a temperature of the air exceeds a threshold based on a signal received from the sensor. When the temperature of the air is below the threshold, the fan can rotate in the second direction. When the temperature of the air is equal to or above the threshold, the fan is inhibited from rotating in the second direction.
