Dayco Curved Radiator Hose for Hyundai Elantra

Dayco 72681 is a curved radiator coolant hose built for the upper cooling circuit on select Hyundai Elantra models. It uses EPDM construction and a single I.D. hose design to match the original routing and connection sizes for a direct replacement on 2007-2012 Hyundai Elantra applications.

The Dayco Curved Radiator Hose line focuses on OE-style fit and routing for cooling system service. This hose follows the curved path needed in the engine bay and is specified to SAE J20R4 Class D-1 and SAE J1684 Type EC standards.

Detailed Description

This Dayco radiator coolant hose is shaped for the upper hose location on the Hyundai Elantra and is sized to match the listed connection points. The curved profile helps maintain the factory-style hose path, while the EPDM material is selected for use in engine cooling systems. If you are replacing a worn upper radiator hose on a 2007-2012 Hyundai Elantra, Dayco 72681 provides a direct-fit service part for that application. This part cross-references Hyundai 25414-2H100 for the same application.

Common Cooling System Issues

  • Cracked or split upper radiator hose
  • Coolant seepage at the hose connection
  • Softening, swelling, or hardening of the hose material
  • Loss of proper coolant flow through the upper hose route
  • Service replacement for a damaged Hyundai Elantra radiator hose

Installation Notes and Tips

Verify the hose routing, end diameters, and upper position before installation. Inspect the radiator neck and engine-side connection for corrosion, residue, or sharp edges that could affect sealing. Drain coolant as needed, transfer the hose along the original path, and confirm clamp placement after the system is refilled and bled.

Quality Assurance

Dayco manufactures this hose to meet SAE J20R4 Class D-1 and SAE J1684 Type EC requirements for cooling system hose applications. The part is built from EPDM and follows the curved upper-hose configuration used on the listed Hyundai Elantra models.
