Radiator fan is intermittent. Only turning on for 10 to 15 seconds at a time

What is your question?

I just replaced the radiator fan two weeks ago. It ran perfectly. No issues. Than yesterday my car started to overheat again. Today I changed out the thermostat. And still the same. I have a 2013 ford edge selling. With the v6 3.5 engine. I ordered a new coolant temp sensor today and will arrive this after noon. But I cannot for the life of me find were it is on the motor?

What makes this problem better or worse?

Idleing

How long has your 2013 Ford Edge had this problem?
