Detailed Description

Dayco 71479 is a radiator coolant hose formed as a curved upper hose for vehicles that require a specific bend and consistent hose diameter. The EPDM rubber construction is suited for cooling-system service, while the single I.D. design and 1 1/16 in. end diameters support a secure connection at both ends. This hose is listed for 1986-1987 Hyundai Excel, 1990-1994 Hyundai Excel, 1991-1992 Hyundai Scoupe, 1987 and 1990-1992 Mitsubishi Precis, 1988-1990 Dodge Colt, and 1989-1990 Mitsubishi Mirage upper radiator hose locations.

Dayco 71479 also cross-references ACDelco 24211L and Gates 21647 for the same application. If you are searching for an upper radiator hose for a Hyundai Excel or Mitsubishi Mirage, this part number helps narrow the replacement to the correct formed hose profile and size.

Common Problems This Hose Can Address

• Coolant leaks from a cracked or aged upper radiator hose
• Softening, swelling, or collapse of the original hose under heat
• Improper hose routing caused by a misshaped replacement
• Loss of coolant from split ends or deteriorated rubber
• Cooling-system service on vehicles with a curved upper hose layout

Installation Notes and Tips

Verify the hose routing, end diameters, and upper-position fitment before installation. Inspect the radiator neck and engine-side connection points for corrosion or residue, and replace clamps if the existing hardware is worn or damaged. Confirm that the hose follows the original curved path without twisting so coolant flow remains unobstructed.

Quality Assurance

Dayco manufactures cooling-system components to published SAE specifications, including SAE J20R4 Class D-1 and SAE J1684 Type EC for this hose. That specification-based construction supports consistent fit and material performance for the listed applications.
