Detailed Product Description

The Gates Molded Coolant Hose 21336 is a radiator coolant hose crafted from EPDM, a synthetic rubber known for its excellent resistance to heat, ozone, and coolant chemicals. This hose features a molded construction, which provides a precise shape tailored to fit specific vehicle coolant system layouts without the need for additional clamps or modifications. With a centerline length of 23.8 inches (605 mm), it is designed to maintain proper coolant flow between engine components. The hose ends have inside diameters of 1.5 inches (38 mm) and 1.75 inches (44 mm), accommodating connections to different radiator or engine fittings. The absence of an internal spring allows for unobstructed coolant circulation, reducing the risk of flow restriction or hose collapse under pressure.
