Getting an oil change, noticed what looks like a build up of residue on the passenger side of the radiator. Truck is a '16 250, 6.2, bought in June 2016, 17k miles, 90% hwy, then some pretty dusty work conditions, but I can safely say that has been less than 10% of it's short life so far. There is a hose directly in front of the radiator at that location, appears to be coming from the transmission cooler. No sign of fluid loss, just the residue on the radiator. Pics below






I don't feel like this is a critical issue, but I do plan to have it taken care of. I'm currently in Florida for work, 7-10s until the 22nd. I live in Alabama, 500+ miles from where I am, though I'm only about an hour from the dealer I purchased the truck from. I'd prefer to monitor this and let my local dealer deal with it, or would you guys consider this more pressing than that?

EDIT: I meant to post in the general Super Duty section, was searching the 6.2 forum for a similar issue

Also, took another look, with no sign of an actual leak, would this be the hose "sweating"??

 

Well, it is obviously leaking. While I do not think it is "critical" nor that you can't wait to take to your hometown dealer, I would clean it up real good, drive it to get it up to temp and rub around the hose to see if it is the clamp or the hose leaking. That should give some confidence of how bad it is leaking.

 

It doesn't look like the hose bit I'm thinking the radiator has a small leak, nothing to critical now but I would have it looked at when you get home.

looks like a small leak at the transmission cooler connector blowing back on the radiator.
