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

  • Q:

    I installed this UPPER hose on my 93 ford tempo, it collapsed. Doesnt this hose require a spring inside?? If so why didnt it come with one? Took cap off refilled after therm opened, replaced cap, took cap off again after collapse, it stayed collapsed.

      I'm glad to assist, Ed! These hoses are reinforced and should not require a spring inside to maintain rigidity in a pressurized cooling system.

      I suggest checking over the rest of your cooling system and, if necessary, have a mechanic test your cooling system. If you need further assistance, try our 'Need expert help?' link further down this page.
