07.5 - 09 3rd Gen 6.7L Powertrain
I have a 08 6.7 with a g56 6 speed, mostly stock. Its already been studding not more than 20k miles ago. Was running around 240f engine temp while driving and would drop back down to 180 when I stopped. It was pushing antifreeze out of the radiator cap and pushing coolant into the overflow tank...
