Radiator problems have a way of building quietly. The engine still runs, the car still gets through the week, and the temperature gauge may stay normal right up until the cooling system finally starts losing control. By then, what could have been a smaller repair can turn into overheating, coolant loss, and a much bigger bill. That is why radiator trouble is worth paying attention to early. What The Radiator Is Really Doing Many drivers think the radiator is just there to keep the engine from overheating. It does that, but the bigger job is controlling heat every time the car is running. Coolant moves through the engine, carries heat away, and then passes through the radiator so that heat can be released before the coolant goes back around again. Once the radiator cannot move coolant cleanly or release heat the way it should, the whole cooling system starts losing ground. The car may still drive normally for a while, but the safety margin gets smaller with every tr ... read more
