I am highly mechanically-inclined and even I have degree in different majors -cars have been always my hobby and I am die-hard DIY in vehicle repairs.
Still when I open the hood of my new SuperDuty, I found heat exchanger that I could not identify. Later found on the net it is liquid-cooled intercooler.
In old days I would investigate such design, but now I rather enjoy my early retirement.
Truck has long warranties and MAYBE I will change oil on it, but don't plan to learn every switch under the hood.
