OVER HEATING WHEN DRIVE BUT NOT WHEN SITTING IDLING

2003 Pontiac Grand Am • 100,000 miles

Car starts running hot when going down road but not when just sitting idling and heater does not blow hot air. I've replaced the thermostat and the radiator but still starts running hot when I drive it down the road

What size engine is in this? It sounds like its airbound, but without knowing the engine size, we cant help you with a proper bleed procedure.
