Hey guys, Finally got everything assembled, my coolant (mostly) put in and one of my radiator fittings keeps leaking. Luckily, it is not in my case but I simply cannot get it to seal right. I clamped it down with a hose clamp, but that leaked. I took the hose off and refit it. I used zipties instead but it always keeps leaking, so how can I make this darn thing seal?

Make _absolutely sure_ that you tighten the little metal things to their tightest with a wrench or something similar, thats probably where the leak is. Once you do, you'll see they can be tightened a lot more, just make sure not to overtighten (the rubbery bits will be pushed out of the spot where they should be, make sure to watch for this) Hope I helped

If you're using brass multi-barb fittings Teflon thread tape did the trick for me.
If it's weeping between the brass and copper fittings Teflon tape should solve
that problem as well.

I used too much flux when silver soldering the copper female fittings to my
heater core which resulted in having to remove the inlet tubes to burn off the
solder that filled the threads; the tight torque required after that oversight left
me with having to apply a thin bead of Gorilla snot to address the weeping
problem........not attractive but functional.

Well I am just using a black ice pro and actually everything is fine now that I am not using any clamps at all. No, I am not using your typical barbs, either. I called Robert (Rock) at DD and he told me he designed the fittings that way. Anyhow, its all good! Finally got my kit up and running, leak tested and Killnine approved. Temps are great and the silence is just so fantastic. No more jet engine sound! Reps for all!
