Gates 51363 lower radiator coolant hose for the 2002-2006 Audi A4 Quattro V6 3.0L and other vehicles carries coolant between the radiator and the engine. This Gates coolant hose is a molded modular assembly with its fittings built in.
A hose that leaks, looks swollen or shows cracks can be worn out. Before you replace it, rule out a loose clamp, a leaking quick connector or a leak at the radiator, since those can lose coolant too. Any visual check is done with the engine off and cool, and a shop can pressure-test the system.
It fits the 2002-2006 Audi A4 Quattro V6 3.0L and the 2002-2005 Audi A4 V6 3.0L. Both cars take a single hose in the lower position.
