Abstract

A method for reversing an air mover to remove debris from a cooling system of a work vehicle. In one embodiment, the largest required fan speed for cooling the engine coolant, hydraulic oil and the charge air is used as the set point speed for a fan. The fan is operated at the set point speed to generate airflow across each of the heat exchangers. Multiple conditions are evaluated for reversing the direction of the fan.
