Should I Add Antifreeze or Water to the Radiator?

[JasonMarie]

Add antifreeze to the radiator. The radiator, also known as the heat exchanger, is a key component in the car's cooling system. Its function is to allow the coolant to absorb heat in the radiator, dissipate the heat when flowing to the heat exchanger, and then return to the radiator for circulation to achieve temperature regulation. The method for replacing radiator antifreeze is as follows: 1. Unscrew the radiator cap and open the radiator drain valve to release the antifreeze; 2. Insert a rubber hose connected to a tap into the radiator filler neck; 3. Turn on the tap to allow tap water to continuously flow through the engine cooling system; 4. During the flushing process, keep the engine idling until clear water flows out of the radiator; 5. Add antifreeze to the radiator.
