Powertrain Oil Cooler
The powertrain oil cooler is mounted at the front of the machine and is part of the cooler group. The cooler group
consists of three separate units: the powertrain oil cooler (Figure 2, Item 1), the engine coolant radiator (Figure 2,
Item 2), and the engine aftercooler (Figure 2, Item 3).
The powertrain oil cooler is a fluid-to-air cooler. Cooling occurs as heat transfers from the hydraulic oil flowing
through the cooler to the air flowing past the cooling fins.
