I have a 2011 ram 1500 automatic trans with 200,100 miles. It over heats but I barely replaced the thermostat and added green antifreeze. There’s no cracks on radiator or coolant lines. No white smoke comes out or antifreeze bubbling up. It used to guest up idling and now reaches high temps even wen driving normal speed. My reservoir is still full with coolant as well whay could it be ?

Your water pump is probably shot. After replacing the thermostat and refilling the system, did you properly burp the air out?

Is your antifreeze mix 50/50? Too high a percentage of coolant will cause overheating.
And if the radiator cap is old change it. Too low a pressure is another cause of overheating.
