Overheating etc

Have an 04 Ranger that overheats once in awhile. There is almost no heat from the radiator. Have already tried a new thermostat. It has a new radiator. Any ideas? v6 engine

What temp is the thermostat? Recheck your work, its very easy to install a thermostat backwards (had a young tech at our dealership do that here the other day on a Jeep). Make sure all the air bubbles are out of the coolant system. Make sure its full. Look in the radiator to verify coolant flow (impellers can break free from the water pump shaft).
