Detailed Description

Dayco 72926 is a curved radiator coolant hose engineered for upper hose placement in Ford Transit-150, Transit-250, Transit-350, and Transit-350 HD models from 2015 through 2023. The curved profile helps match the factory routing path, while the EPDM rubber construction is suited for coolant circulation in demanding underhood conditions. This hose is identified as a dual I.D. hose, with different inside diameters at each end to match the cooling system connection points. If you are sourcing a Ford Transit upper radiator hose or a Dayco 72926 replacement for a 2015-2023 Transit van, this part number is the direct reference to verify before ordering.

Dayco’s Curved Radiator Hose line focuses on shaped coolant hoses that follow vehicle-specific routing and connection sizes. For Transit van cooling repairs, that means a hose designed around the upper radiator path rather than a universal straight section. This part cross-references Gates (e.g., 22926) for the same application.

Common Problems This Hose Can Address

• Cracked or hardened upper radiator hose material
• Coolant seepage at the hose connection points
• Improper hose routing after a cooling-system repair
• Replacement needs for a damaged Ford Transit upper hose
• Service issues caused by an aging EPDM coolant hose

Installation Notes and Tips

Verify the vehicle year, model, and upper hose routing before installation. Confirm the end diameters match the cooling-system connections on the Ford Transit-150, Transit-250, Transit-350, or Transit-350 HD application. Inspect clamps, necks, and adjoining components for wear or corrosion before installing the new hose, and make sure the hose follows the original curved path without twisting.

Quality Assurance

This Dayco radiator coolant hose is manufactured to SAE J20R4 Class D-1 and SAE J1684 Type EC specifications for cooling-system hose applications. Use the part number 72926 and the vehicle fitment details to confirm the correct replacement for your Ford Transit upper radiator hose service.
