Your temps are normal too in stop and go traffic. I had to do the conversion but 212F coolant temp at stops is normal with the OEM thermostat. As far as the CEL, mine overheated at 250 miles due to a stuck thermostat. If I recall right the warning light came on at 240 or 250F. I could be wrong though. I made a thread about it maybe I mentioned it in there.Thanks.
Any idea about the IATs?
Hi, it was 250 when the light came on http://www.hellcat.org/threads/2016-challenger-hc-overheated-250-miles.15731/#post-363234Could you post the link to the thread.
Good to know.
