It has been a long time since I've been on the forum, but came back to see if I could get an answer on an issue that has been bothering me. Last December I bought a 2021 SRT (new) as a third vehicle for us to use some around town and to our lake house. (It fits easily in the garage, is fairly small compared to our other vehicles, etc.) My issue is coolant temps. I'm an exceptionally anal retentive sort and do all of my own PMs, and other light maintenance. When driving the Jeep, normal cruising temperature is 203 or 204 degrees. This isn't terrible, but probably about 5 degrees warmer than most other modern vehicles I've owned - no big deal. When in traffic, or at a long light however, the doggone thing will climb as high as 221 degrees before the fan kicks on to start bringing it down. I don't like this in the slightest. It stresses the heck out of me. I realize that modern vehicles are engineered to operate warmer due to emissions, but this swing just isn't "cool" with me (pun intended). Conversely, our 2021 Escalade operates between 197 and about 206 on the high side...and of course my 6.7L Powerstroke, well heck-it is a diesel...I can sit in traffic forever. I've tried the search function here on the forum, but have found nothing specifically about this issue.
