Product Details

Dayco’s Curved Radiator Hose line is engineered for formed cooling-system routing where a straight hose will not match the vehicle layout. This upper radiator coolant hose uses EPDM material to handle engine coolant exposure and temperature cycling, while the integrated heat shield adds protection in high-heat areas near the engine bay. The dual I.D. design supports the specific connector sizes used on these Ford trucks, helping maintain a proper upper hose connection on the radiator side and engine side. Dayco 72633 is a direct replacement choice for 2011-2016 Ford F-250 Super Duty and Ford F-350 Super Duty upper radiator hose service.

What It Helps Fix

• Cracked or hardened upper radiator hose material
• Coolant leaks at the hose connection points
• Heat-related hose deterioration near the engine
• Incorrect hose routing on Ford Super Duty cooling repairs
• Fitment issues when replacing the upper hose on F-250 Super Duty or F-350 Super Duty trucks
