From what I've seen on the 6.0 section on FTE. It's the EGR cooler tube. They leak often on the 6.0.

I havenot gone to the dealer yet. I'm going to run it a bit longer and see how much i'm loosing.

As for the Vormax it works great when the coolant is flowing. But, since I lost so much I don't think it was flowing back there any longer. The hoses to my Hotfox were not even warm when I got home on Friday. The Vormax is after the Hotfox so I doubt it was seeing any heat.

I'll let everone know how it goes wen I get around to getting it fixed
