This hose is located on the back of the oil cooler sandwich plate. It is used to transfer coolant to and from the oil cooler sandwich plate to the engine. Over time this hose may wear down and tear causing coolant to leak out. This could cause the engine to overheat. If the engine overheats, it could damage other components within the engine.
