Abstract

A method for determining when a cooling system for a work vehicle is restricted with debris. A first temperature difference between an inlet and an outlet of a heat exchanger is determined when the airflow though said heat exchanger is substantially unrestricted. When a subsequent temperature difference is less than the first temperature difference by a predetermined amount, the direction of the airflow is reversed to remove debris from the heat exchanger.
