We have the 180 deg thermostat installed in our 2010 Rubicon. To get the true benefits you should run a programmer to lower the temp ON of the Fan. So it turns on earlier. We run the Superchip at 185*F for low,med and High speed. The benefits are cooler engine temp and lower temp under hood when crawling or driving at low speed on the trail.
Otherwise, if you do not use a programmer you are only starting the Cooling cycle earlier (coolant circulation) but not really cooling the engine more.
Keep in mind that we are in South Florida no snow here.
