The heat is great, just replaced the radiator & thermestate. But while driving it over heats, but not at idle.

Do you have an actual boiling over or just the gauge that's telling you that it is?
Cooling fan/s coming On? if okay test the water pump
One way to test for a bad water pump is to squeeze the upper radiator hose when the engine is hot and idling. Careful, because the hose will be HOT! If you do not feel much coolant circulating through the hose when you rev the engine, the pump may be bad.
If it continues to overheat-Get it block and pressure tested.
