The radiator in a vehicle is installed to perform a critical function, which is to keep the entire engine from overheating. When the engine of a vehicle is running, it tends to overheat easily; and to prevent that from happening is the reason a radiator exists. The main task of the radiator is to provides with a coolant that keeps the engine from heating up, and breaking down. As when the engine overheats, it tends to shut down. The coolant provided by the radiator runs through the engine, and cools it down in the process. Then the coolant passes through the radiator, where it is cooled down again, so the process can begin all over again. This process keeps repeating throughout the engine of the vehicle is running. The radiator in vehicles comes with two separate tanks, which are connected using brass or aluminum tubes. So when the coolant passes through them, the radiator fan starts blowing air to cool down the coolant.
