What is Engine Oil Cooler?
A heat exchanger, similar to a small radiator, through which engine oil passes and is cooled by airflow. An oil cooler for small internal combustion engines is provided. The oil cooler comprises a heat exchanger mounted on the external surface of the engine crankcase, directly below the flywheel. The heat exchanger has an inner serpentine passageway in flow communication with the lubrication path of the engine oil. The heat exchanger further has a plurality of external fins, said fins being positioned directly below the flywheel. The flywheel includes a plurality of inlet apertures for drawing in cooling air to be blown over the heat exchanger.
