Detailed Product Description

The Dayco Curved Radiator Hose 70501 is a dual inside diameter hose made from EPDM, a synthetic rubber known for its durability and resistance to heat, ozone, and coolant chemicals. This hose features a 1 1/2 inch inside diameter on one end and a 1 3/4 inch inside diameter on the other, allowing it to connect different sized radiator fittings securely. It does not include a heat shield or protective sleeve, focusing on straightforward, reliable coolant transfer. The hose meets SAE J20R4 Class D-1 and SAE J1684 Type EC specifications, ensuring it adheres to industry standards for radiator coolant hoses. With a trunk height of 17 inches, it is designed to fit specific radiator layouts in Ford and Oldsmobile trucks.

About the Curved Radiator Hose Product Line
