Dayco Curved Radiator Hose 71256

Dayco 71256 is a curved radiator coolant hose built from EPDM and finished in black for cooling-system service. With a 1 5/16 in. inside diameter at both ends, it is a single I.D. hose for direct replacement use in select Chevrolet, Mitsubishi, and Nissan applications.

Key Features

  • EPDM construction for coolant-hose service
  • Black finish for a clean OE-style appearance
  • 1 5/16 in. inside diameter at both ends
  • Single I.D. hose design
  • Meets SAE J20R4 Class D-1 and SAE J1684 Type EC specifications
  • Curved radiator hose profile for routed cooling-system connections

Product Details

The Dayco Curved Radiator Hose line focuses on replacement hoses shaped for specific cooling-system routing. Part number 71256 is a curved radiator coolant hose that follows the factory-style path used in select vehicles, helping maintain proper coolant flow between the radiator and engine connections. This hose is listed for 2006 Chevrolet HHR lower tee-to-engine applications with oil cooler, 1996-1999 Mitsubishi Eclipse lower applications, and several Nissan upper hose applications including D21, 200SX, and Pathfinder. This part cross-references Gates 20893 for the same application.

What This Hose Helps Address

  • Coolant leaks from a cracked or aged radiator hose
  • Softening, swelling, or collapse in an original hose
  • Improper hose routing after cooling-system service
  • Loss of coolant circulation caused by hose deterioration
  • Fitment issues on select Chevrolet HHR, Mitsubishi Eclipse, and Nissan upper hose applications

Installation Notes

Verify end diameters, routing, and position before installation. This hose is listed for lower and upper positions depending on vehicle application, including 2006 Chevrolet HHR lower - tee to engine, 1996-1999 Mitsubishi Eclipse lower, and 1984-1989 Nissan 200SX, D21, and Pathfinder upper applications. Confirm whether the vehicle is equipped with power steering on the 1987-1988 Nissan Pathfinder listing, since fitment notes differ by configuration. Inspect clamps, mating tubes, and nearby cooling components before refilling the system.

Quality Assurance

Dayco manufactures this hose to SAE J20R4 Class D-1 and SAE J1684 Type EC specifications, supporting consistent material and performance requirements for radiator coolant hose replacement.
