Check Vehicle Fit

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:

Leaked before I even started the car! I replaced several hoses at the same time as this one and had no issues with leakage. This one was showing a drip at the factory installed tee even before I finished filling the reservoir. I will use a different brand in the future.

    Took about 1/2 hour to install and required slight trimming of about 1/2" on one end of hose for exact fit. Works fine-no problems.

    Comments about CARQUEST by Dayco Curved Radiator Hose:

    When installed, the hose was kinked. It isn't long enought to cut to fit because of the design (Ford). Leaked and I had to use a regular clamp to fix this problem. I hope the kink doesn't effect the performance.

    By design it is hard to install and isn't a quality issue.
