I have a 2006 6.0 with 103k and is blowing coolant out the cap only when the truck is towing or working. I have a sct with xtreme race and rcd's hot race, intake, exhaust, egr delete, arp studs and black onyx gaskets all put in 5k ago. I didnt know if anybody had any other ideas why this is happening.

when you tow, do you put on a tow tune? and how heavy are you towing?

I either put it in a tow tune or usually stock. I tow pretty heavy with a 28 foot gooseneck trailer but not very often. Its mostly a pleasure vehicle
