First of all, welcome to the City!!! Sorry you are having issues with your Escape.
Unfortunately, my 2016 Escape doesn't have the tow package installed so I am not sure what the proper answer to your questions are.
Prior to this Escape, I had a 2014 Escape that I used to tow a pop up travel trailer in the middle of summer. I had no issues with coolant temperature. The travel trailer didn't weigh what you are towing so that may be part of the reason I had no issues.
