Detailed Product Description

The Dayco Curved Radiator Hose 71019 is engineered from EPDM (ethylene propylene diene monomer) rubber, a material known for its excellent resistance to heat, ozone, and coolant chemicals. This hose is designed as a dual inside diameter hose, with one end measuring 1 1/2 inches and the other 1 3/4 inches, allowing it to connect different sized fittings within the cooling system.

With a trunk height of 20 inches, it fits the cooling system routing of Jeep CJ5, CJ7, and Scrambler models accurately.

The Curved Radiator Hose product line by Dayco focuses on providing hoses that accommodate specific vehicle cooling system geometries, such as bends and curves, to ensure proper coolant flow and fitment. This hose is part of that line, designed to replace factory curved radiator hoses with precision and durability.
