Buy a Ford cap and see what happens. If it does it again and you've done oil cooler and EGR delete, then I'd say you have a bigger issue.

You are keeping your coolant below the min. line on the bottle?

Well I try keeping the coolant below the min line win I started having all these issues around 55000 miles I just would put some coolant in *** neede win running then win u turn truck off to let it cool it would be full then Ofcourse win I would pull camper it would blow it out I would add more didn't think of any of these issues then bc I didn't no bout the 6.0 7 months!!! I had this stuff done last week and I drained everything while it was running and put straight antifreeze in it?? Well next morning the coolant level was at the seem where molded together and it blew a bunch out!!! Next morning I looked and it was just under min line so I added little to it and its been fine but I gota pull camper home and I'll let u guys no if it blows any out on my 5 hour drive home? But if u can think of anything let me no maybe I over filled it a lot I don't still learning lol!! Thanks guys

The degas bottle should be filled to the MIN line on the bottle when cold.

Another question? I put straight coolant in my truck after I deleted Egr cooler? Is it supposed to have 50/50 or is straight coolant fine!! I talk to a guy he said just out straight coolant in these trucks don't no what to believe on that one!!
