F350 Super Duty vs 3500 Denali vs The Ike Pulling 30k lbs

From what I have read and what I have scene in past reviews, the L5P Duramax normally runs at 210F coolant temps even unloaded which is where it was at in the video the whole way up. I zoomed in on the second gauge from the left which is coolant temp. The Cummins fan kicks on at 219F so if it kicks on when they do that run then you know it at least got as hot as the PSD. Although, since the coolant does not cool down hot air coming from the turbocharger and going into your engine, it would not have any effect on EGT's.
