According to Charles and the LN website, the stock t-stat starts to open at 186* and doesn't fully open until 210 or so. This creates some real hot pockets within the engine itself. The low temp t-stat starts to open around 166* and is fully open by 184*, IIRC. Lower coolant temp equates to lower oil temp, which in the long run, could save your engine.
