• Description:

  Leaking coolant? Avoid costly engine damage by replacing your worn hose with the Genuine Audi Lower Radiator Hose 5Q0-122-051-CT, a factory-original replacement that includes the essential quick-disconnect fitting.

  This OEM lower radiator hose is the direct-fit solution, engineered with exact diameter, bends, and quick-connect ends to match Audi's factory specifications. Easy to install and built to last, it’s your peace of mind for daily drives and long road trips alike. If you notice signs of coolant leakage or hose damage, this replacement is the fix you need.
