If your car overheats while driving but not at idle, even after replacing several parts, it might be an airflow or pressure issue. Check that the radiator fans run at full speed when the engine is hot. A clogged radiator or a small head gasket leak could also be the culprit. Make sure nothing is blocking airflow to the radiator. If the problem persists, a professional pressure test might be needed.
