Oil Cooler: Description and Operation

DESCRIPTION





Engine coolant is used to cool the oil. A plate-style external heat exchanger is located in the valley of the cylinder block, below the EGR cooler. Two gaskets seal the oil cooler to the cylinder block. Replace the gaskets whenever the oil cooler is removed or replaced. The oil is fed to the oil cooler through the oil filter. With a maximum cooling power of 15 kW (51,200 BTU), the oil cooler ensures the maximum oil temperature does not exceed 135�C (275�F). After the oil cooler, the oil is fed to the balance shaft tunnel, which is simultaneously the main oil gallery of the cylinder block.
