I noticed looking at my 2018 F150 and noticed that there are two set of motorized fins (dampers) that seem to open and close, I'm guessing to limit the cold air going to the radiator during cold weather. Never seen anything like this before. Can anyone explain the operation of these fins, (or did I just do that)
Question about fins in front of radiator
