Detailed Product Description

Gates 19371 is a molded heater hose engineered for applications that require a formed hose path rather than a universal straight section. Its 18.4-inch centerline length and 0.63-inch inside diameter at each end support the factory routing used on the 2003-2006 Toyota Camry and 2003 Toyota Solara at the intake manifold to heater connection.
