About the Dayco Curved Radiator Hose Product Line

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 engineered to maintain coolant flow efficiency while fitting tightly within engine compartments. The 72184 part exemplifies this with its branched design and multiple inside diameters, tailored for Dodge Ram trucks.

Detailed Product Description

Its branched configuration features three distinct inside diameters—1 3/4 inches, 2 inches, and 31/32 inches—allowing it to connect multiple points within the cooling system. The hose’s black color matches OEM standards, ensuring a consistent look under the hood. While it does not include a heat shield or protective sleeve, its material composition and SAE certifications guarantee durability and compliance with industry standards.
