They changed the lug pattern in 2011 to provide heaver duty components and larger brakes.

The oil in the throttle body is most likely from the PCV System. The suction hose comes from the right valve cover and enter the intake system right at the throttle body.

There may be a coolant level sensor, that indicates on the DIC. But the engine will not be shut off when the coolant gets low, or when the engine gets to hot. That would be a safety hazard if your overheating truck shuts off in the middle of a busy intersection.

The engine could shut off when it gets hot enough and the clearances get tight.

Did you run it after the you put the radiator in?
