Abstract
A work machine with a remote diagnostic system includes a combustion engine, a pump, a coolant temperature sensor to monitor and transmit a coolant fluid temperature, a pressure sensor coupled to an inlet of the pump, and a controller. The pressure sensor is configured to monitor and transmit a coolant fluid pressure. The controller is operatively associated with the engine, the coolant fluid temperature sensor, the pressure sensor and an equipment care advisor module. The equipment care advisor module is configured to monitor the coolant fluid temperature during a start-up of the work machine, monitor the coolant fluid pressure during the start-up of the work machine, calculate an expected coolant fluid pressure based on the monitored coolant fluid temperature and the monitored coolant fluid pressure, and generate a failure code indicating a combustion gas leak when the monitored coolant fluid pressure exceeds the expected coolant fluid pressure.
