Remove the plug and let the coolant come out of the radiator. As soon as you have done that get a garden hose put it in the radiator start up the engine and let it warm up so the clean water from the hose circulates around the whole system a few times. Don't forget to get the heater going to clean out the heater core too. After you've done this put everything back together and bleed the system.

Check that you can actually do this on a Gladiator as it's a newer vehicle and the ECU might not like it
