A control system for controlling a work machine includes an engine for producing power to propel the work machine during a normal operating mode, a cooling system for cooling at least the engine during the normal operating mode, and a controller for controlling the cleaning system during the normal operating mode and a clean operating mode. During the normal operating mode, the engine is running and the controller operably controls a cooling fan of the cooling system to rotate in a first rotational direction to produce a first air flow in a first direction. During the clean operating mode, the engine is not running and the controller operably controls the cooling fan to rotate in a second rotational direction to produce a second air flow in a second direction. The first rotational direction is opposite the second rotational direction, and the first direction is opposite the second direction.
