Ok I have a 2004 6.0 and coolant is coming out of the cap. Generally I would think head gasket issue since the truck has had the egr deleted but no coolant in oil?????? Not sure what the problem is or what else could be causing this. Also sometimes the truck runs a little rough like its kind of missing out or maybe not getting enough fuel I have no clue anyone help me? Thanks.

How much coolant is coming out of the bottle?

How full is the bottle?

It's a pretty good amount of coolant coming out of the cap.

Full to the stamped max line on the side of the bottle or the min line?

Ford issued an update and a stick a few years back.

The stamped min line is the actual max fill line

Then youve either got a bad cap. Or bad gaskets

Well dang hopefully it's just a bad cap. Any ideas on the running rough thing?

Not without actually seeing an example. But bad gaskets can cause a rough running concern

It doesn't do it all the time or even that often

Im having the same issue kinda. when it first did spew out i knew it had too much fluid in it so i let it burp out all it needed to then rechecked the level. I turned the program down to 50 hp towing and put a new cap on yesterday i havent noticed anything since then. My old cap also had a whistle to it when the psi got to high (i'm guessing) new cap no whistle. I have egr delete and studs

The only way to know for sure if you have a real problem is to check for exhaust in the coolant (know as "Block Test" at radiator shops).
