This radiator hose set is designed for SK450-8 and SK460-8 excavators and includes both upper and lower hoses for the engine cooling system. The upper hose (YNF03941) transfers hot coolant from the engine to the radiator, while the lower hose (YNF03942) returns cooled coolant back to the engine. Together, they ensure efficient coolant circulation and stable engine temperature under normal and heavy-duty operation.
