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

      Comments about CARQUEST by Dayco Curved Radiator Hose:

      I used this lower radiator hose on my 1997 Ford Expedition, and other than the unique way Ford has this hose connect to the radiator, the installation went smoothly. Since I wasn't sure how Ford wanted it to attach to the radiator, I used two hose clamps and I havent had any problems.

          The Dayco Curved Radiator Hose - Part No. E71963 is a custom fit branched radiator hose. Automotive manufacturers started using branched hose because it provides a more leak proof coolant system. This part is compatible with the following vehicles: Ford Expedition V8 5.4L (1997-2002), Ford F-150 V8 5.4L (1997-2001), Ford F-250 V8 5.4L (1997-1999), Lincoln Blackwood V8 5.4L (2002-2003) and Lincoln Navigator V8 5.4L ((1998-1999 and 2003). To remove the end you should fold back the tab, rotate hose and pull apart.
