Abstract
A system and method including one or more conduits, a pump system, and a controller. The conduits are fluidly coupled with a cooling device that is operably coupled with an engine to cool at least a portion of exhaust from the engine. The pump system pumps a cleaning fluid from a cleaning fluid source through the one or more conduits and into a flow path of a portion of the exhaust from the engine while the engine continues to operate. The controller monitors operation of the engine and determines whether the engine is operating in a designated state. The controller controls the pump system to pump the cleaning fluid into the flow path of a portion the exhaust from the engine to clean the cooling device while the engine operates in the designated state and the exhaust flows from the engine and through the cooling device.
