The car radiator is responsible for preventing the car engine from overheating. When the engine is in use, it produces a lot of friction and heat, and the radiator uses coolants to keep the engine running at a healthy temperature. The radiator is connected to the engine with channels through which a liquid is pumped. This liquid can be water or another coolant, such as antifreeze. By taking the liquid through the engine, it heats up the liquid and takes it outside of the engine to let it cool down. It is usually located in front of the vehicle's grille in order to benefit from the airflow as the the vehicle moves.
