Detailed Description

Dayco 71910 is a formed radiator coolant hose engineered for upper radiator routing where a curved profile is required. The EPDM construction is suited to coolant service, while the matched 1 7/16-inch inside diameters at both ends support a proper connection to the cooling system.

This part cross-references Ford (e.g., F6SE-8B274-BC, F6SZ-8260-A) for the same application.

What This Hose Helps Address

• Cracked or split upper radiator hose material
• Coolant leaks at the hose body or connection points
• Collapsed or softened hose sections from age and heat
• Incorrect hose routing on Ford Thunderbird and Mercury Cougar cooling systems
• Replacement needs for a formed upper radiator coolant hose

Installation Notes and Tips

Verify the hose routing, end diameters, and upper-position application before installation. Inspect the radiator neck, engine outlet, and clamps for wear or corrosion, and replace any damaged sealing surfaces before installing Dayco 71910. Confirm clearance around nearby components so the curved hose follows the original path without kinking.

Quality Assurance

Dayco 71910 meets SAE J20R4 Class D-1 and SAE J1684 Type EC specifications, supporting standardized coolant-hose requirements for the listed applications. The Dayco Curved Radiator Hose line is built for vehicle-specific cooling-system replacement needs.
