Detailed Product Description

The Dayco Curved Radiator Hose line is engineered to provide reliable coolant flow in demanding automotive cooling systems. Part number 71896 is a dual inside diameter hose, meaning each end has a different inside diameter—1 7/16 inches on one end and 1 19/32 inches on the other—allowing for a secure and proper fit on specific radiator and engine connections. Constructed from EPDM (ethylene propylene diene monomer) rubber, this hose offers excellent resistance to heat, ozone, and coolant chemicals, ensuring durability and longevity in the cooling system. The hose is black in color and does not include a heat shield or protective sleeve, which is consistent with many OEM radiator hose designs. It complies with SAE J20R4 Class D-1 and SAE J1684 Type EC standards, confirming its suitability for automotive coolant applications.
