The ZX160 ZX180LC Upper Radiator Hose YNF19034 is a cooling system component designed for compatible ZX160 and ZX180LC excavator applications. Installed in the upper section of the cooling circuit, the hose helps transfer engine coolant between the engine and radiator to support stable temperature control during machine operation.
The radiator hose operates under changing temperatures, coolant pressure, engine vibration, and demanding construction-site conditions. Its flexible rubber construction allows normal engine movement while maintaining a reliable coolant passage and helping reduce the risk of leakage around the cooling circuit.
The 3107945 / 4447526 upper radiator hose is suitable for replacing hoses that have become cracked, hardened, swollen, aged, or damaged. Maintaining a reliable upper coolant connection helps support proper coolant circulation and effective engine heat management.
This replacement hose is suitable for excavator maintenance, cooling system repair, and scheduled replacement. It is a practical choice for machinery dealers, repair workshops, equipment maintenance companies, and B2B excavator spare parts buyers. Before installation, the part number, hose shape, connection points, and machine model should be checked against the existing hose for proper compatibility.
