2200 Combo running hot !

[Sammus]

put much heavier oil in the centre diff. i bet your centre diff is unloading and making the motor rev out harder that it should be, look for the front wheels panning.

I know a billion of my friends have complained about hot motors on their 3 diff cars, and every time it's because the centre diff unloads too easily and the motor revs super hard with minimal load on it.
