Abstract
A system and method operate by, while an engine is operating, automatically determining whether the engine is in a designated state for EGR cooler cleaning. The EGR cooler is operably coupled to the engine to receive hot EGR from an exhaust of the engine and to provide cooled EGR to an intake of the engine. The system and method also include, responsive to the engine not being in the designated state, automatically preventing a water pump system from introducing a cleaning liquid into a gas inlet of the EGR cooler.
