A used OEM Audi coolant / water hose, part number 4H0122447C, sourced from a donor vehicle. This genuine rear coolant hose is designed for the 3.0L supercharged V6 (supercharged DOHC) in the Audi A8 Quattro. Over time, the rubber can crack or leak at the connection points, causing coolant loss and overheating. The hose is from the rear engine circuit, where access is tight and failures are common.
