If your car begins to overheat when idling, but the temperature gauge moves back down once you get going, it’s most likely due to a broken radiator fan. When the coolant goes to the radiator, it’s spread over a large surface area to cool it down. Airflow further cools it before it returns to the engine.18 mar. 2019
