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 heatsink or heat exchanger for one or more power modules of an inverter or a converter comprises a coolant flow channel, comprised of a plurality of coolant flow channel portions that form a switchback or serpentine flow path, and that is adapted to circulate coolant inside the heat exchanger or heatsink. One or more vents can be provided inside the heat exchanger or heatsink to pass air from one coolant flow channel portion to an adjacent coolant flow channel portion.
