Abstract
A locomotive includes an engine (), an intercooler (), and an oil cooler (), each having respective cooling passages formed therein. The locomotive also includes a cooling system () in selective communication with the respective cooling passages for selectively providing a first coolant () and a second coolant () at a higher temperature than the first coolant to the cooling passages. A method of operating the cooling system includes providing, in a first mode, a first coolant flow () to the intercooler and a second coolant flow () to the oil cooler at a first temperature different than the first coolant flow to achieve preferential cooling of the intercooler. The method also includes providing, in a second mode, the first coolant flow to the intercooler and the second coolant flow to the oil cooler at a second temperature different than the first coolant flow to achieve preferential cooling of the oil cooler.
