A car radiator is a crucial component of a vehicle's cooling system. Its main job is to keep the engine from overheating by dissipating heat. As the engine runs, it generates a lot of heat, and the radiator helps to cool down the engine coolant that circulates through the engine. This process ensures that the engine operates efficiently and prevents damage. Radiators are typically made of metal and have a series of thin tubes and fins that allow air to flow through. When the car is moving, air passes through the radiator, cooling the hot coolant inside. This cycle helps maintain the right temperature for optimal engine performance.
