      • Motorcraft Part# KM4679

      Stay Cool. Old cracked or split radiator hoses are not efficiently cooling your engine which can cause it to overheat leaving you stranded. So maintain your Mustangs cooling system by replacing your old brittle hoses now before it's to late.

      Direct Fit. This is a genuine Ford Motorcraft lower radiator hose that has all the correct bends and curves for a perfect fit replacement on your Mustang, it is not a cheap one size fits all universal hose you get at the local parts store that you have to fight with to install.

      Application. This Ford Motorcraft Lower Radiator Hose is a direct fit replacement for the 2003 to 2004 SVT Cobra and Mach 1 Mustangs equipped with a DOHC 4.6L V8 engine.

        5 2003 Cobra - Robster

        Better than before

        I haven't installed it yet, but its identical to the one currently on my 03 Cobra, with the exception that this one comes with one side of the hose having a Ford clamp attached to it. They didn't come with these before from Ford, at least not the early years of part replacement. So that's a great bonus.

        Quality hose and exact fit

        Very easy to determine the correct hose for my '03 Mach 1. Motorcraft quality and an exact fit. 'Nuff said.

        Factory fit!

        Great and easy installation, hose fit just like a glove. No leaks, no problems. As other hoses may be to small or big.
