Dayco 71962 Radiator Coolant Hose - Upper

Curved Upper Radiator Hose for Ford Trucks

Dayco 71962 is a curved radiator coolant hose built for upper cooling-system routing on select Ford trucks and SUVs. Made from EPDM rubber and formed to match the application, it provides a direct replacement for vehicles that need a 1 23/32-inch inside diameter at both ends.

The Dayco Curved Radiator Hose line focuses on application-specific hose shapes and OE-style fitment for cooling system service. This hose is specified to SAE J20R4 Class D-1 and SAE J1684 Type EC standards for radiator coolant use.

Installation Notes and Tips

Verify the hose routing and end diameters before installation on your Ford F-150, Expedition, F-250, or Lincoln Navigator application. Inspect the mating necks, clamps, and surrounding cooling-system components for wear or corrosion before installing Dayco 71962. Confirm the hose is positioned as the upper radiator hose and seated fully at both ends.
