The Radiator is a crucial component of cooling system. It is responsible for regulating the engine's temperature by transferring heat from the coolant to the air passing through it. The radiator works by circulating coolant through a series of small tubes that are surrounded by fins. As air flows over these fins, it absorbs the heat from the coolant and cools it down before returning to the engine. The radiator is typically located at the front of the vehicle, behind the grille, and is made up of an aluminum or copper core with plastic or metal tanks on either side. A damaged or malfunctioning radiator can cause overheating and serious damage to your engine, so it's important to keep it well-maintained and replace as needed.
