Try venting the cooling system where it say to vent when filling..... Mine did the same thing until I did it. I had a air bubble from installing the egr delete.....

Coolant wont fly out, just open the plug until you have coolant coming out and tighten it back up...... Not trying to offend anyone but make sure the truck is cool when you do this.
