Curved radiator hose for heavy-duty cooling

Dayco 70902 is a curved radiator coolant hose built for demanding cooling-system routing in medium- and heavy-duty applications. It uses EPDM construction and a dual I.D. design to match different connection sizes while maintaining a secure coolant path.

Key features

  • EPDM rubber construction for coolant-system service
  • Dual I.D. hose design with 2 1/4 in. and 2 1/2 in. ends
  • Curved profile for routed cooling connections
  • Black finish for a clean OE-style appearance
  • Built to SAE J20R4 Class D-1 and SAE J1684 Type EC specifications

Detailed description

This Dayco radiator coolant hose is intended for applications that require a curved hose with different inlet and outlet diameters. The 70902 part number appears in fitments for Ford F-650 and Ford F-750 lower radiator routing, along with International 4300, 4300LP, 4400, 4400LP, 3200, and Durastar applications. It also cross-references Ford D0HZ-8260-L and D0HZ-8260-P for the same application. The hose construction and SAE specification references make it a practical replacement for cooling-system service where shape and size matching matter.

What it is used for

  • Replacing a worn or cracked radiator coolant hose
  • Restoring coolant flow in curved hose routing
  • Addressing leaks at mismatched or aging hose connections
  • Servicing lower radiator-to-pipe or pipe-to-radiator connections
  • Supporting cooling-system repairs on Ford F-650, Ford F-750, and International medium-duty trucks

Installation notes and tips

Verify the hose routing, end diameters, and position before installation. This application list includes lower and upper routing variations, plus some cut-to-fit configurations, so match the vehicle’s original hose path and connection sizes before replacing the part. Confirm clearance around nearby components and inspect clamps and mating surfaces during service.

Quality assurance

Dayco manufactures cooling-system hoses to published SAE specifications for material and performance consistency. Part number 70902 is built for fitment-specific replacement use in the listed Ford and International applications.
