Dayco 72622 Radiator Coolant Hose - Upper

Dayco Curved Radiator Hose 72622

Dayco 72622 is a curved radiator coolant hose built for upper cooling-system routing on select Ford Super Duty trucks and Excursion models. Made from EPDM rubber with a black finish, it matches the shape and connection size needed for direct coolant transfer in the engine bay.

This Dayco curved radiator hose is engineered for vehicles that route around the serpentine belt, helping maintain the factory hose path without requiring serpentine belt removal during service.

Key Features

• EPDM construction for coolant hose service
• Black finish for OE-style appearance
• Single I.D. hose design
• 1 3/4 in. inside diameter at both ends
• Outside diameter: 1 5/32 in. at both ends
• Built to SAE J20R4 Class D-1 and SAE J1684 Type EC specifications
• Curved radiator hose profile for upper hose routing

Fitment Details

• Fits 2000-2003 Ford Excursion, Upper; routes around the serpentine belt; serpentine belt removal not required.
• Fits 1999-2003 Ford F-250 Super Duty, Upper; routes around the serpentine belt; serpentine belt removal not required.

Dayco 72622 is a direct-fit style upper radiator coolant hose for Ford Excursion, F-250 Super Duty, and F-350 Super Duty applications that use the curved hose layout. The hose’s EPDM material and SAE-rated construction support coolant circulation in the upper cooling circuit while maintaining the correct bend and end sizing for the listed vehicles. This part cross-references Ford F81Z-8260-CA and Motorcraft KM4351 for the same application.

What It Helps Address

• Cracked or hardened upper radiator hose material
• Coolant leaks at the hose connection points
• Incorrect hose routing around the serpentine belt
• Loss of proper coolant flow through the upper radiator circuit
• Fitment issues from using a hose with the wrong bend or diameter

Installation Notes and Tips

Verify the hose routing before removal so the replacement follows the factory path around the serpentine belt. Inspect the radiator neck, engine connection points, and clamps for wear or corrosion before installing the new hose. Confirm the 1 3/4 in. end diameters match the vehicle’s cooling-system connections.

Quality Assurance

Dayco manufactures this hose to SAE J20R4 Class D-1 and SAE J1684 Type EC specifications, supporting consistent material and dimensional requirements for cooling-system service.
