If you are replacing a worn lower radiator hose on a Ford F-250 Super Duty or Ford F-350 Super Duty, part number 73049 provides the correct curved layout for the listed fitments.

Key Features

Product Details

Dayco’s Curved Radiator Hose line focuses on application-specific hose geometry for vehicles that require a formed lower coolant hose rather than a universal straight replacement. Part number 73049 uses EPDM rubber, a common material for radiator hose service, and its matched end diameters support a direct fit on the listed Ford Super Duty applications. For buyers searching for a 2011-2016 Ford F-250 Super Duty lower radiator hose or a 2011-2016 Ford F-350 Super Duty lower coolant hose, this part number 73049 is the relevant match.

The hose measures 21 1/2 in. in trunk height and does not include a heat shield or protective sleeve. Its curved profile helps preserve the factory-style routing needed in the lower cooling circuit, where hose shape and clearance are important for proper service replacement.

Common Replacement Reasons

• Cracked or aging lower radiator hose
• Coolant seepage at the hose body or ends
• Softening, swelling, or collapse from heat and pressure
• Incorrect hose shape after a previous repair
• Loss of proper coolant flow due to a damaged hose

Installation Notes

Verify the vehicle year, make, model, and lower hose routing before installation. Inspect hose clamps, necks, and adjacent cooling-system components for wear or corrosion, and replace any damaged parts as needed. Confirm that the hose seats fully on both ends and follows the original curved path without twisting.

Quality Assurance

Dayco manufactures this hose to SAE J20R4 Class D-1 and SAE J1684 Type EC specifications for radiator coolant hose service. Part number 73049 is built for the listed Ford F-250 Super Duty and Ford F-350 Super Duty applications.
