A used genuine Audi coolant hose, OEM number 4G0121109S. This left-side water hose routes coolant in the 3.0L supercharged V6 (found in certain A6 and A7 Quattro models). Over time, the rubber can crack or develop pinhole leaks, causing coolant loss and possible overheating. The part's reinforced construction helps withstand the pressure of the cooling system.
