Can antifreeze and water be mixed together for use?

[Trent]

Antifreeze and water can be mixed together for use, but long-term use of antifreeze diluted with water can cause significant harm to the car. Adding water to antifreeze lowers its boiling point. The boiling point of water is 100 degrees Celsius, while antifreeze typically has a boiling point above 110 degrees Celsius. When water is added to antifreeze, it dilutes the antifreeze, thereby reducing its boiling point accordingly. This can lead to the phenomenon of the coolant boiling over. Additionally, adding water to antifreeze diminishes its rust and corrosion prevention properties. Antifreeze's ability to prevent rust and corrosion is due to certain additives it contains. When water is added to antifreeze, the effectiveness of these additives in preventing rust and corrosion decreases. This can result in the formation of scale inside the radiator or corrosion of the radiator, leading to coolant leakage or seepage.
