Abstract: A crack detection system for a cylinder head associated with an internal combustion engine of a locomotive is disclosed. The crack detection system comprises: a closed-loop coolant system for cooling the cylinder head; a sensor assembly including a pressure sensor, and a speed sensor; and a controller in communication with the sensor assembly. The controller is configured to monitor a coolant pressure feedback and an engine duty cycle of the internal combustion engine. The controller is further configured to communicate an alert signal indicative of an existence of a crack in the cylinder head when: coolant pressure signals are greater than or equal to a first threshold and less than a second threshold; a pressure decay is calculated greater than a third threshold.
