[QUOTE="Danarch, post: 441714, member: 21093"] [USER=19161]@Anybodyhome[/USER] have you had any more issues with this? My wife’s Sahara CEL came on today. She arrived home and I pulled the code, was P0128. It is a 2015, with 88K. I have no idea if any of the coolant components (including coolant) have been replaced. We just bought it about month ago, had all the fluids except coolant changed. 1. The DIC showed as high as 226 on the way home. So I assume once up to temp it is running in the normal range. 2. Heater blew hot air (doors and freedom top off, outside temp around 55-60 this morning). She said it seemed to warm up normal. 3. Not sure about when the cooling fan kicks on, I wouldn’t hear it anyways. 4. Overflow is almost to max line, but it is still warm. 5. Will check radiator when it cools down. Best I can tell since it reaches operating temperature and not overheating it seems like it would be safe to drive till I get it fixed. 1. Did you have an infrared device to get the temp on the upper hose to see of matched the Jscan app or were you estimating temp by feel? 2. Before replacing the t-stat in your post above are saying the temp never exceeded 185-190? Ours is reaching 226 and then drops back down. [/QUOTE]
