Dayco 72054 Radiator Coolant Hose - Upper

Dayco 72054 Curved Radiator Hose Overview

Dayco 72054 is a curved radiator coolant hose built for upper cooling-system routing on select Ford E-350 applications. Made from EPDM rubber and formed as a single I.D. hose, it provides a direct replacement option for vehicles that need a 1 3/4-inch inside diameter at both ends.

Compatible with 1995-2000 Ford E-350 Econoline, 1996-2000 Ford E-350 Econoline Club Wagon, and 1999-2000 Ford E-350 Super Duty, this curved radiator hose is a practical choice for restoring proper coolant flow in the upper hose position. The Dayco 72054 part number is also a useful reference when matching the correct replacement hose.

Product Details

Dayco’s Curved Radiator Hose line focuses on formed coolant hoses that match the routing and shape needed for specific vehicle cooling systems. This hose is engineered as a curved upper radiator hose for Ford E-350 models, helping maintain the correct path between cooling-system connection points. The Dayco 72054 is a direct-fit style replacement for applications that require the listed diameter and formed shape.

This part cross-references Ford XC2Z-8B274-EA and Motorcraft KM4502 for the same application.

Common Cooling-System Issues It Can Address

• Cracked or hardened upper radiator hose material
• Coolant leaks at the hose connection points
• Collapsed or weakened hose sections under heat and pressure
• Incorrect hose shape after a previous replacement
• Restricted coolant flow caused by a deteriorated hose

Installation Notes and Tips

Verify the hose routing, end diameters, and upper-position fitment before installation. Inspect the radiator neck, engine connection, and clamps for wear or corrosion before transferring the new hose into place. Confirm that the hose follows the original curved path without twisting or kinking so the cooling system can operate as intended.

Quality Assurance

This Dayco radiator coolant hose is manufactured to meet SAE J20R4 Class D-1 and SAE J1684 Type EC requirements, supporting consistent material and performance standards for cooling-system service.
