Engine Fan

Ive owned two 6.7 trucks, a 2012 and currently have a 2013. I can hear the fan running on a cold start and continue to hear the fan speed increase with engine speed for the first 5-7 minutes of driving and then I dont hear it any more. This even happens on cool mornings 50-degrees. If the engine is off for a few minutes after driving it does the same thing all over again. The 2012 truck I had did not do this which is why im concerned. I suppose it's possible Ford changed something about the fan operation however it makes no sense to me why this fan would need to be blowing and sounding like a jet taking off on a cold start and first 5-7 minutes of a drive. Anyone else with a 2013 have this same event?

Yep, '13 F-250 does it. Try page 58 in your diesel manual. The more you know the less chance a dealer can dazzle you with bovine scat.
