To start off, My friends truck is a 2008 6.4 bone stock 70k miles.

For a while now it has been losing coolant, over a period of time. in about a week or so it will lose around a quart. There are no visual cues like puddles on the floor when parked for a while, or a smell of coolant.

Now i know that on a 6.0 this is probably the EGR, and i do know that the 6.4 have two. I guess international thought that since the first one was such a huge success they should add another one. (damn EPA)

So my best guess is that it is one of the EGRs. Let me know what you guys think.

With only 70K on it, I'd take it back to Ford and have the cooling system pressure checked.
