This Audi coolant hose (OEM 4K0122109AA) is a genuine used line removed from a salvage vehicle. It also replaces the earlier 4K0122109J variant. Designed for the 2.9L and 3.0L V6 MHEV turbo engines found in the A6 Quattro, S6, and S7, this hose circulates engine coolant; a cracked or swollen line can cause external leaks and gradual overheating.
