It’s actually 2 separate radiators and they do not mix there is a second belt driven water pump for this.
Fish is correct it’s the fuel and trans coolers on the secondary system.

I was wrong. I finally had time to login to my Ford technical diagrams at work and found out that they did revise it with the new engine. Only the fuel cooler is hooked up to the intercooler now and it is separate from the primary system. The trans cooler is now on the primary system along with the EGR which connected these two initially. I really need to start looking at this stuff more often, but since we only have nine Ford dealerships (versus 120 Peterbilt/Navistar), most of my time is spent with them and Cat/Cummins.
