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.

Abstract: A cooling package mounting assembly for a machine is provided. The cooling package mounting assembly includes a first elongated frame member and a second elongated frame member. The cooling package mounting assembly also includes a first top coupling bracket, a second top coupling bracket, a first bottom coupling bracket and a second bottom coupling bracket. The cooling package mounting assembly includes a mounting arrangement coupled to at least one of the first elongated frame member and the second elongated frame member. In a first configuration, the mounting arrangement is configured to removably support a first type of heat exchanger of the cooling package between the first elongated frame member and the second elongated frame member. In a second configuration, the mounting arrangement is configured to removably support a second type of heat exchanger of the cooling package between the first elongated frame member and the second elongated frame member.

Abstract: A cooling system is provided. The cooling system includes a first heat exchanger and a second heat exchanger. The first heat exchanger has a first chamber and a second chamber. A plurality of tubes is provided in the first heat exchanger such that the tubes are in fluid communication with the first chamber and the second chamber. The tubes are arranged in a plurality of rows. A baffle is located in the second chamber. The baffle divides the second chamber into a first region and a second region. The first region of the second chamber is in fluid communication with at least one row of tubes. Further, an outlet is provided in fluid communication with the first region. The second heat exchanger includes an inlet in communication with the outlet of the first region.
