The Audi 4.2L V8 coolant hose (OEM 079121055F) is a used genuine part that carries engine coolant between components in the cooling system. Also called a water hose, this molded rubber hose can crack or develop pinhole leaks over time, leading to coolant loss and potential overheating—especially on the naturally aspirated DOHC V8 found in A6, Allroad, and S4 models.
