It mainly did it going up hill or at around 40 mph at 1300 rpms. Just like the WK2 guys with the 3.6 engine.

It’s going to surge/buck regardless what you do because of lack of power and tunning.

The job of the thermostat is to monitor the engine temperature and engage the fan once it exceeds operating temperature.

It should activate automatically as the engine temperature fluctuates.
What to do when your quadratec engine gets hot?
The Jeep dealer said the fix was to install some insulating material between the injector rail, and the intake manifold. That did not fix it. The only way it will start again after getting hot, is to open the hood and let some heat escape. This works for me every time if I wait long enough (usually just 10 minutes or so.)

Why do you check both hot and cold transmission fluid?
The reason for checking when both hot and cold is transmission fluid expands as it is heated.
