Dayco Curved Radiator Hose Product Line Details

The Curved Radiator Hose line by Dayco focuses on providing hoses with specific bends and branches to accommodate complex cooling system layouts. This product line is designed to replace original equipment hoses that require precise curvature and multiple connection points, such as those found in Volkswagen Beetle and Jetta cooling systems. The 72740 part exemplifies this with its branched design and multiple diameter ends, ensuring proper coolant flow and fitment.

Technical Description and Specifications

The Dayco 72740 radiator coolant hose is made from EPDM, a synthetic rubber known for its excellent resistance to heat, ozone, and automotive fluids. The hose features three inside diameters: two ends at 1 1/4 inch and one branch at 9/32 inch, with corresponding outside diameters of 1 17/32 inch and 9/16 inch respectively. This branched hose design supports complex coolant routing in Volkswagen Beetle and Jetta models. The hose does not include a heat shield or protective sleeve, focusing on direct coolant transfer within the radiator system.

Applications and Problem Solving

• Replacement for worn or cracked radiator coolant hoses in Volkswagen Beetle and Jetta
