[QUOTE="Randall Manley, post: 459662, member: 25291"] Got the same problem with my 2015 wrangler.No leaks no coolant in oil no smoke from back fan running it is loud. When started it up the temperature goes up quickly and when running at high rpm’s it will climb up to 240. Had thermostat changed several months ago everything was fine until couple weeks ago. I took a thermal heat gun and check everything under the hood when the gages were showing 230 and Nothing under the hood was the hot upper hose was 180 lower 170 thermostat was 160 temperature sensor was 170 heads 180.
