Now let me see if I have this correctly.I can't let the truck sit, I cant let the truck idle, and I have to put some type of additive in the fuel system for it to perform correctly. Yea !

This vehicle did not overheat.The extreme heat set off a fire suppresion system.The heat sensing wires complete a circuit at about 340 f. All fluids are ok. No exhaust leaks. I am involved with a fleet of 6.0.This is not the first time for this problem.I could fill up this web site with the problems I have.Average milage on fleet is about 45,000 miles

Has anyone seen evidence of extreme (320+)under hood temps on E series vans?
