Why does my car overheat when in traffic?
Modern cars are equipped with an electric radiator fan that moves air through the radiator and cools down the antifreeze inside. When traveling at higher speeds, there is enough airflow across the radiator that the fan typically isn’t necessary. That’s why the engine temperature rises when you’re stuck in traffic.
