loosing coolant

[crash86]

ive got an 05 6.0 and im loosing coolant but i dont know where its going
i have replaced the egr cooler once before. Im thinking headgasket but its not blowing any white smoke or smelling funny and also it smells like coolant when you pop the hood, but no signs of leaks and also put a dye in the coolant too. also the radiator isnt building pressure like it should be.

I think its the headgasket but then again i think if it was it would have water in the oil after a few days of setting.

Anybody got any ideas?

when my truck blew the headgaskets it was building up to much pressure and puking coolant out the resivor.how fast & much coolant are you losing?could it be a cold seal leak?my neighbor has a 06 and it was the waterpump leaking

Yup, shes most likely puking out the degas bottle. Is the underside of the hood whitish/stained above the degas?
