  • Made with synthetic EPDM rubber compounds that provide resistance to deterioration from ozone, coolants, and temperature variations of -40°F (-40°C) to +257°F (+125°C)
  • The inner base tube is reinforced with knitted rayon for maximum strength and burst resistance for the life of the hose
  • Meets SAE J20R4, Class D-1 requirements for improved service hose
  • Meets Type EC electro-chemical requirements as specified in SAE J1684; which eliminates premature deterioration of the inner tube caused by the build up of static electric charges

Losing faith in Advance Auto Parts lack for quality issues

    • ID was too large, hose lasted less than a year

      Comments about CARQUEST by Dayco Curved Radiator Hose:

      Not impressed with the poor quality and sloppy tolerances of the Advance Auto Parts. Not worth the savings of a few dollars when the part needs replacement a year later. The ID was too large on this part and it failed less than a year later. Went to NAPA with the correct ID for a better fit.

        Comments about CARQUEST by Dayco Curved Radiator Hose:

        The hose is exactly what I needed. I tried to order the upper and lower hose. I could only order the upper hose online. Tried calling the 800 number and they were absolutely no help. I could not find the lower hose in stock in any of their local stores. I ending going to Pep Boys to buy the lower hose.

        Wrong inside diameter

        About Me Mechanic

        Comments about CARQUEST by Dayco Curved Radiator Hose:

        This hose measured out at 1.37in to 1.40in while the stock hose for a Hyundai Elantra measures out at 1.26 after years of use. This allows the hose to slip on and off with no effort leaving me weary of a good seal. I would not recommend this for a Hyundai Elantra.
