Should I Add Water or Coolant to the Car Radiator?

[AutumnLynn]

You should add coolant to the car radiator. The car radiator, also known as the heat exchanger, is a key component of the vehicle's cooling system. Its function is to dissipate heat. The coolant absorbs heat in the water jacket, flows to the radiator to release the heat, and then returns to the water jacket to circulate, achieving temperature regulation as part of the car engine. The car radiator is mainly composed of the radiator core, water pipes, cooling fins, upper tank, and lower tank. The upper tank is located on the radiator and is connected to the lower tank via water pipes. As the hot water flows from the upper tank to the lower tank, it cools down. The cooling fins form air channels, and with the help of the fan's suction and the relative wind speed when the car moves forward, a large amount of cold air passes through these channels, absorbing the heat from the coolant flowing through the pipes and then dissipating it into the atmosphere.
