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

    Old one comes out with some difficulty. Having a perfect fit replacement takes some of the reinstall pain away. Decided to replace the existing hose while doing a mandatory replacement of a separate item at the same time, just in case. For under 15 bucks, may as well, cause its hot out there. I try to stay from under the hood unless I have too.
    Advance could idiot proof these hoses by marking the inlet & outlet ends. Yes I started installing backwards (bottom on top, top on bottom), but ODs were sized differently so, somewhat idiot proof...

    My water pump was about to go out. (belt was noisy and the pump would make a terrible screeching upon start up if not already warm) I decided to replace the pump, upper and lower hoses, thermostat then flush the system, add coolant and bleed. Got to the upper hose and it looked different then then the one installed. It is longer than the original and when installed, does not fit correctly in orientation I tried. Any orientation I turn it it has a kink in it. I even tried switching the ends, no luck. I GUESS you could cut it and make it fit but I returned it and bought another from someplace else that was an exact match. Car runs fine now. I like shopping at advance and this is the first time they have let me down. Will replace the belt later as it looks ok for now.

    Comments about Dayco Curved Radiator Hose:

    This was an upper radiator hose for an 04 Grand Prix. The hose was NOT a direct replacement and as others commented you will most likely need to trim it slightly for the best fit. I took about an inch off radiator side and other than that it is a good replacement hose.

      Comments about Dayco Curved Radiator Hose:

      It's a hose. I'm not sure what all can be said about it. I put it on when my old one got a hole in it and it fixed it. The only reason it was easy to install is because it was the top one.

                          This hose was almost perfect, I had to remove 1-1.5 inches off from one side of the hose. Now that the hose was modified so that the curves would be flush with the engine.

                            If you are doing a coolant drain and/or flush you might as well change the hoses as rubber does not last forever. This is an easy install and cheap insurance against a breakdown.
