The Audi RS4 auxiliary radiator coolant hose (OEM 8E0121058B) is a used genuine replacement for the left-side coolant line. This hose channels coolant to the auxiliary radiator in 4.2L V8 RS4 models. Over time, the rubber can crack or leak, causing coolant loss and potential overheating. The line is a direct-fit part for the naturally aspirated 4163cc and 4172cc engine variants.
