no coolant in degass bottle
hey guys i have 2004 6.0 with a 5'' straight pipe exhaust afe stage 2 and spartan free tunes. recently i noticed i have no coolant in my degass bottle. its bone dry. i'm assuming this isn't good. i had the coolant at the minimum line like your supposed to, cause it used to puke a little bit under high boost or a load on the motor. after running the tunes for awhile it basically went dry. i guess what i'm asking is there an internal leak somewhere or what? is it evaporating? its not leaving a puddle and there's no white smoke at all. i tuned back to stock the truck has 113,000 miles stock hg's and no egr delete YET!
