New guy here with 6.0 issues!
Hey guys im new on here. so alright hes what i got going here i have a 2004 ford f 250 with a 6 speed manual tranny 4x4. I bought the truck with 105,000 miles on it, at 115,000 i did a full egr delete and last week at 120,000 i did a new oil cooler all my temps seem to be good the truck eot and ect are acctually colder then they were to begin with. it has a drop in filter and 4 inch banks exhaust just driving the truck around im okay but only when i am towing a trailer i am puking coolant from the degas but it only pukes to where their is no coolant in the degas then it quits. cold its probbly an inch below in min mark on the degas bottle. ive been told its my head gaskets. but i hade the coolant checked for contamination and im clean so im stumped, anyone have any ideas? i would appreciate it thanks!

What do you mean you had the coolant checked for contaminants? What were you checking for?
You say it doesn't puke when the degas bottle is empty, but when that happens how do you know you have enough coolant in the system? It clearly won't "puke" when there isn't enough coolant "to puke".
You need a pressure gauge on the degas bottle, but with an EGR delete, it sure does sound like head gaskets.
How hot is the coolant getting?

As you keep diluting it, you will puke more and more .... and before long you will allow boilng to happen inside the engine. That can cause problems. Water boils at 212 (with zero back pressure). Coolant (50/50) boils at 223 degrees with no back pressure. It may not sound like much difference, but it is!

You need to quickly determine what the problem is. A pressure gauge on the degas bottle is the quickest way I know of, but only you can say how dilute the system is. Personally, I wouldn't want to be driving it at less than a 40% coolant mix.

Here's a video on how to measure the cooling system pressure to diagnose a head gasket failure.

IMO the video has some mistakes. One mistake is that you CAN get some white smoke with leaking head gaskets (usually it is slight and it will be primarily at start-up). Leaking EGR coolers can also result in some quick pressure rises in the degas bottle (it is not just head gaskets leaking that does this). The only 100% sure way to tell if it is an EGR cooler vs a head gasket issue is to remove the EGR cooler and pressure test (or vacuum test) it. Of course if you have a proper EGR system delete, the troubleshooting is easier.
The thread in the Tech Folder is pretty much from the TSB - with a few exceptions.
I certainly do NOT advocate the EDAS system or getting his "hero kit".
The way he hooks up the pressure gauge is a good way to do it.
