Posting because I was looking for this information before I did a coolant flush and thermostat change and couldn't find a definitive answer, maybe this will help someone else.
Stock thermostat that came out of my 2013 Taurus limited is 180 degrees. I was confused because all the options on rockauto are 180 except for the motorcraft thermostat which is listed at 190. Pictures attached if anyone is interested.
Just getting in to doing some routine maintenance myself, and this forum has been real valuable for learning, thanks all.
