The radiator hose set consisting of YNF13257 and YNF13258 is designed for R110-7 excavators. The upper hose (YNF13257 / 11N3-40110) channels hot coolant from the engine to the radiator, while the lower hose (YNF13258 / 11N3-40120) returns cooled coolant from the radiator to the engine. Together, they provide efficient coolant circulation, stable engine temperature, and reliable performance during continuous or heavy-duty operation.
