07.5 - 09 6.7L Powertrain
This 07 is new to me. Owned less then a year. Pulled a heavy lumber load, moving at 65mph down the highway, it got warm, not hot. Once I hit town, with traffic and 45mph. it got hot. Pulled over to let engine fan cool it off. It did not. peaked at 236, shut off and let cool before moving on...
