Update I finally had some time and checked into the overheating issue. Found when I removed the radiator temp switch from sensor, and went to use a jumper wire to test fan. The wires in the connector popped out and were not going in, and or staying. So bent tabs back and was able to get wires to stay in for now. The fan works as you said with key on after jumping it. Did some researching and found a harness and rad temp sensor on Amazon. So just ordered and will let you guys know how it works out. Sorry it took a while to respond. Now to the shifter linkage adjustments for popping out of gear.

I am new here on the forum so wanted to thank you all for posting this info. It is helpful as I have 2 Coleman UT400's (2020 & 2021 models) Found similar issues as you Ray. So, this is what I've found so far. The overheating/temp light is on. No leaks and isn't low on coolant. Fan is not turning on, unless I jump 12 volts to it then works fine. All fuses in fuse box under seat are working and not blown. The temp sensor located on engine seems to have an open when doing an OLM test with meter. Tested the other SXS's known good one and got an OLM reading. So, I swapped them and didn't make a change on either SXS. Back to the drawing board until now. Ill check the thermistor switch soon and get back to you on my results. In the meantime, Ray did your parts come in? and any progress or updates? Also unrelated I believe... both horns on the same vehicle don't work. Haven't got far yet on testing them but has voltage to them from switch, but not sure of ground. Figured I'd ask if anyone had any info while on here. I'll be doing more diagnosis soon and will update if anything changes. Just thought it was strange both horns are inoperable. Thanks again for your advice.
