hey guys, i have a 2001 E7 460 heavy spec, i haul trains of cement and fuel total weight about 55000kg (120000lbs) the truck runs beautiful the only problem is that on hot days when lets say going up hill my engine oil temp gauge goes into the red at 250 and then my exhaust temp starts going up too and when it hits the 250 mark also the auto-shut off buzzer on and i have had a shut-down a few days ago. My coolant temp always stays in the green and never moves into the red. Nobody seems to know why it does that your help is much appreciated.
