The oil cooler line is vital because it allows oil to travel through the engine so it can operate as smoothly as possible. The line contributes to cooling down the oil and sends it back to the engine.
Oil cooler line operationEngine oil lubricates important moving components inside the engines of the vehicles. The engine oil cooler helps extend the oil's life and its capability to lubricate. The oil cooler operates by having the oil flow out of the engine by way of the oil cooler line, through the oil cooler, and back to the engine. Hot oil also passes via the tubes so the heat is transmitted from the oil to the tubes and the fins. So air flowing via the cooler will eliminate any heat from the fans.
