CARQUEST by Dayco® Molded Radiator and By-Pass hoses are designed to provide the high strength and resistance to oil, mud, salt, road debris, ozone, coolants, and temperature variations required for a superior performance replacement hose.

Product Features:
  • 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

    Leaks in 6 weeks


    from Kennesaw, GA

    Comments about CARQUEST by Dayco Curved Radiator Hose:

    6 weeks after installation, the hose started leaking at the connection between the top hose and the T joint.


    Leaks after less than 1,000 miles


    from Atlanta area

    Comments about CARQUEST by Dayco Curved Radiator Hose:

    After less than 1,000 miles, the hose started a small slow leak at one of the joints on the T-joint. I will have to drain the system (big pain considering that the drain plug is frozen), disassemble the radiator support bracket to get to the bottom clamp, and then I'll be able to remove the old one to get a replacement.

    • Q:

      Why do you sell this hose it's just plain junk, there are lots of other good quality suppliers that sell hoses for this application. Seems like I was one of many to buy this and have to replace it within the first 1000 miles.
