Next time you've got your head under the hood of your 6.7, take a look at the heater inlet fitting.The factory plastic barb gets brittle with age and heat, and sometimes it feels like all you have to do is look at it wrong for it to break. They break all the time during service, or even while simply driving down the road, causing a large coolant leak.
Our billet heater inlet top adapter replaces that weak point, with a billet part, without replacing the entire hose.Cut the plastic clamp, install the new fitting, and move on. Inexpensive part, quick install, eliminate the failure risk for good.
