Where did the intercooler go?
I owned a 99 F350 and went to the dark side (GMC) in 2007, but I am back as a 2017 F350 owner. I was looking under the hood the other day and noticed (I think) that the intercooler radiator has been changed to some kind of "box" on the driver side" of the motor. When did this happen and what is in this "box" that cools the post turbo air before it is sucked into the engine?
Thanks,
Mike

Interesting, A box that circulated 200 degree water is better than a big radiator that pulls in sub 100 degree air. Being an engineer, I guess that the boys at Ford determined that the "water box" provides cooler air to the engine than the intercooler.

The 6.7 has two completely separate cooling systems...two radiators, two water pumps, four thermostats. The second cooling system runs considerably cooler (140F if I recall correctly) and that is the system used for cooling the charged air.

probably how they get 440 hp / 925 tq (reliably) outta the 6.7L motor vs 210-275 / 475-525 (out of the 7.3L)

The intercooler is run off of the secondary cooling system which rarely goes over 120* unless you are towing heavy. Normally stays around 90-110*.
