If you go back on this board 2 or 3 years you will find that there have been many complaints zackly like yours.. In EVERY complaint the jeep was NOT overheating.
I have thought for a long time that the gauge is more sensitive than the gauges on other vehicles.
It seems that a 10* rise in temprature pushes the needle farther toward the red line than other vehicles. Although the driver THINKS the engine is too hot it really isn't.
Our advice in all instances is to drive the jeep until it pukes it's coolant out.. It seems they NEVER do!
The gauge is only there to warn the driver of a potential coolant loss. As long as the coolant remains in the engine the engine CANNOT get too hot! ONLY without coolant can your engine be hurt by heat. Your engine really LIKES 20 or 30 degrees over the normal 200* operating temprature.
