Audi Coolant Vent Hose / Line, OEM 420121439, is a genuine used part from a donor vehicle. This hose helps release air from the cooling system, preventing vapor lock and overheating. On the Audi R8 with 4.2L V8 or 5.2L V10 engines, a cracked coolant vent line can cause coolant loss and engine temperature spikes.
