Hey y'all! I found this forum, specifically this thread, while googling the symptoms of my 2016 Wrangler overheating. I hope y'all don't mind me piggybacking. I was experiencing similar issues as OP and have had my thermostat changed twice (after market not Mopar - I'm told there's a nationwide back order on Mopart thermostats). After the thermostat is changed everything is fine for a few weeks then bam! We're running hot again and it progressively gets worse.
My girl is currently at the mechanic and we're all scratching our heads. There are no leaks. The radiator has been thoroughly burped. The fan comes on as it should, and he didn't see any signs of issues with head related parts. He also changed the temp sensor today. Currently it's idling at 230 degrees according to the digital gauge inside, and according to the mechanic's computer...BUT it's reading around 150 - 170 degrees when the cooling components are temped with an ir thermometer. Any words of wisdom?
My mechanic is the best in town when it comes to virtually any other car, but he's admittedly not a Jeep expert. He says he actually has two other clients with similar issues and would like to get all of us fixed up.
PS - apologies in advance if I use the wrong terms. I'm a woman and know just enough to be dangerous lol
