The Porsche upper radiator coolant hose / line (return) OEM 99710662603 is a used genuine part removed from a donor vehicle. This right-side return line carries coolant from the radiator back to the engine on Porsche 911, Boxster, and Cayman models equipped with 2.7L–3.8L H6 engines (both naturally aspirated and turbocharged). A failing hose may cause coolant leaks or engine overheating.
