Overheating problem fixed?

I have had two check engine codes about bad thermostats and replaced them. My latest problem was overheating at freeway speeds but no engine light. Engine cooling fan was on constantly. Replaced thermostat again with Motorad recommended by Jeep parts guy at dealership. NAPA had it, cooling fine now, even the gauge is showing slightly below center and no fan running. Have replaced oil cooling tower, pressure sensor, oil pump and four thermostats in the last two months with only 68,000 miles on a 2012 Wrangler...what next?

 

If you’re not experiencing any overheating problems then you should be GTG. You’ve replaced multiple parts already except the radiator.
