After the oil filter, the oil is fed into the bottom of the LCOC (layered core oil cooler) mounted to the crankcase on the front right side of the engine. Under heavy load or high rpm operation, heat is transferred from the oil into the coolant. Under light load and cruising conditions, the oil temperature is regulated to the coolant temperature for optimal fuel efficiency and oil quality. Oil exits the top port of the LCOC and is returned into the crankcase.
