Stop leak is not the problem. Air in the system is . With a leaky radiator you’ve most likely run it low and trapped air in the system when you refilled it. If the stop leak didn’t help then it’s time to change the rad. Stop leak can only fix minor leaks. Your rad is likely cracked somewhere. Refill the system carefully with the car pointing uphill if possible. Use the bleeder valve near the thermostat to bleed out any air in the system. After that you should be good, but continue to keep an eye on the temperature for the next little while.
