Ford F-150 2014 STX 5.0 4X4 140000 miles
Fan is on high speed, Truck is not overheating, Fan kicks on while driving, started shortly before I had a leak in the upper radiator hose. Fixed the leak, installed new T-Stat, and refilled with 50/50. Radiator fans will kick on after driving for 10 mins or so and will not stop until I shut the truck off.
