Doosan 185Y00282A Upper Water Hose Assembly

The 185Y00282A upper water hose is a direct replacement component for the engine cooling system of Doosan and Daewoo DH225-7 hydraulic excavators. It connects the engine water outlet to the radiator inlet, facilitating coolant circulation under operating pressure and temperature. Constructed from high-temperature resistant rubber compounds reinforced with textile or wire braid, the hose is formed to OEM geometry for precise fitment and sealing. It withstands coolant system pressures and thermal cycling typical of heavy-duty diesel engines. The part replaces OEM number 185Y00282A and is compatible with Doosan DH225, DH225-7, and DX225LCA models. Installation requires standard hose clamps and coolant refill per service manual specifications.
