Curved Radiator Hose for Toyota and Hyundai

Dayco 71679 is a curved radiator coolant hose made from EPDM for dependable coolant transfer in select Toyota and Hyundai applications. It is a black, single I.D. hose with 1 3/16-inch inside diameter ends and SAE J20R4 Class D-1 / SAE J1684 Type EC compliance.

The Dayco Curved Radiator Hose line focuses on OE-style hose geometry and material selection for direct replacement service. This hose is built for upper and lower cooling-system routing where a curved profile is required, including Toyota MR2 Spyder, Toyota Camry, Toyota Solara, and Hyundai Accent applications.

Key Features

  • EPDM construction for cooling-system use
  • Curved radiator hose profile for routed coolant lines
  • Single I.D. hose design with 1 3/16-inch ends
  • Black finish for a factory-style appearance
  • Meets SAE J20R4 Class D-1 and SAE J1684 Type EC specifications
  • Dayco part number 71679 for catalog and service lookup

Application Details

Compatible With 2000-2005 Toyota MR2 Spyder, upper pipe-to-pipe and lower pipe-to-pipe curved radiator hose positions; 1999-2003 Hyundai Accent, upper curved radiator hose position; 1992-2001 Toyota Camry, lower curved radiator hose position; and 1999-2001 Toyota Solara, lower curved radiator hose position. This part cross-references Toyota 16572-03031 for the same application.

Use Dayco 71679 when replacing a worn or heat-aged coolant hose in a vehicle that requires a curved routing path and matching 1 3/16-inch hose ends. The hose dimensions and SAE-rated construction support proper coolant flow in the radiator circuit.

What It Helps Address

  • Coolant leaks from cracked or deteriorated hose rubber
  • Softening, swelling, or collapse in an aging radiator hose
  • Improper hose routing on curved coolant connections
  • Loss of sealing at pipe-to-pipe or radiator hose junctions
  • Service replacement for a damaged Toyota MR2 Spyder, Camry, Solara, or Hyundai Accent hose

Installation Notes and Tips

Verify hose routing, end diameter, and position before installation. Match the upper or lower application exactly as listed for your vehicle, and inspect adjoining pipes, clamps, and coolant condition during service. Confirm the hose is seated fully on both ends before refilling and bleeding the cooling system.

Quality Assurance

Dayco manufactures this hose to SAE J20R4 Class D-1 and SAE J1684 Type EC standards for cooling-system service. The EPDM construction and OE-style curved profile support consistent fitment across the listed Toyota and Hyundai applications.
