Colant???

This is a job 3 truck & has the venturi T. I noticed last week that I had coolant all down the drivers side under the front wheel, frame, radius arm, shock I mean every where. Also has it blown up under the hood. I had the truck on the 275 spartan tune & was out playing in it the night before & thought that had something to do with it. But turned it down to 210 tune & pulled a 6000lb trailer to Florida & back & same thing , coolant all down the driver side. I have the dpf pulled off & don't want to take it in for warranty work & change all me parts around if I don't have to so any help is appreciated.....Were is it coming from..

The infamous blown radiator. Just because your truck has the venturi fix, doesn't mean it can't happen. To buy a new rad I think is 600 bucks or so. So you are better off to put it back to stock, and take it in.

i agree radiator is leaking

Its coming from the cap....I just got back from a 1500 mile trip towing the whole time & maybe only leaked down a 1/2''. I figured if it had a blown rad that it would leak out a little faster then that????? or am I just denying the obvious???

Mine leaked out slow. I can't remember how much in x amount of miles. What made me look was the cooling fan was kicking on a lot more often loaded with 14k, and back home just the trailer. The second time I noticed it I got out of the truck, and I could smell coolant.

It may NOT be the radiator. There are quite a few people starting to comment on coolant overflow at the degas bottle, (referred to as "puking coolant"). Seems to be more common on tuned trucks than stock ones, but the same issue remains for both. More info in this thread:
Puking Issues

Also, on The Diesel Garage. They have a couple of huge threads about it. Some guys that have sent their trucks to Elite for other work/mods are waiting to hear back on the source of the degas bottle overflow. Some say head gaskets (drawing from the 6.0 problems), and others, a flaw in the EGR system/coolers that is allowing exhaust gas to escape into the system, overpressurizing it. The deaeration line for the cooling system sits between the egr coolers and the degas bottle, so any exhaust leak into the coolant will head directly for the bottle in a hurry.
