I have a 2013 jeep wrangler unlimited Sahara with the 3.6L and at high way speeds it over heats I’ve replaced the thermostat, water pump, fluid
i have flushed the radiator and have checked for clogs there isn’t any I smell antifreeze but don’t notice a drop in coolant levels the fans work and there isn’t coolant in my oil I don’t have anything blocking the radiator such as winches or anything
I have burped the system
please let me know what I should do next

Welcome to JKF.. A question, what is the temp reading on the gauge? Is it boiling the coolant over? When the thermostat was changed on mine, it took 4 Burping sessions to rid the system of Air.. A sign more burp is needed is when the engine cools (like overnight) the top rad hose will be collapsed or have sunk in places so look before starting.

Welcome! I had a freind that had sand casting in his block...sounds like you have checked for that- but his was a long process of flushing to get it all cleaned out. If your getting good flow- then I would try another thermostat... They are cheap... and sometimes you get that one bad one...
