Dayco 72151 Curved Radiator Hose

Dayco 72151 is a curved radiator coolant hose built for specific upper and lower cooling system applications. Made from EPDM rubber and finished in black, it provides the formed routing needed for a proper coolant connection in select Chevrolet, Toyota, and Lexus vehicles.

The Dayco Curved Radiator Hose line focuses on OE-style hose geometry and material selection for direct replacement service. This hose follows the original curved profile and uses a single I.D. hose design to match the cooling system layout on the listed applications.

  • Black finish
  • Single I.D. hose design
  • End 1 inside diameter: 1 9/32 in.
  • End 2 inside diameter: 1 9/32 in.

Use Dayco 72151 when replacing a curved radiator hose that must follow the factory routing and maintain the correct inside diameter at both ends. This part cross-references Gates (e.g., 22825, 23080) for the same application.

What This Hose Helps Address

  • Coolant leaks from a cracked or aged radiator hose
  • Softening, swelling, or collapse in the hose body
  • Improper hose routing after a failed replacement
  • Loss of coolant flow through the upper or lower radiator connection
  • Heat-related deterioration in the cooling system hose

Installation Notes

Verify the hose position, end diameters, and routing before installation. Inspect the mating necks, clamps, and nearby cooling system components for wear or corrosion, and replace any damaged parts before refilling the system. Confirm the hose is seated fully and routed without twist or contact points.

Quality Assurance

This hose is built to SAE J20R4 Class D-1 and SAE J1684 Type EC specifications, supporting consistent material and performance requirements for radiator coolant service.
