Did you fill her by Cummins manual

Yep, done more than a few times on her. She is running great, temp is steady, nothing weird going on with the coolant level, tested for exhaust gasses in coolant, nothing. I can't figure this out, I'll wait until morning and fire her up cold and see what happens. See if I can actually see where it is coming from. Yesterday, it was definitely spraying out of the cap, I saw that. Today, it looked like the front of the motor, but the fan was running, coolant everywhere! Maybe it is just the cap. We shall see in the morning unless someone else has any ideas?
