Can coolant be mixed with water?

[OJosie]

Coolant should not be mixed with water, as it can easily cause scaling and affect the boiling point in summer, leading to overheating. Functions of antifreeze: Antifreeze does not cause corrosion to the engine cooling system and also has anti-corrosion and rust-removal functions. The boiling point of water is 100 degrees Celsius, while high-quality antifreeze coolant typically has a boiling point above 110 degrees Celsius, preventing overheating during summer use. Premium antifreeze is made with distilled water and contains anti-scaling additives, which not only prevent scale buildup but also help remove existing scale. Antifreeze replacement cycle: Generally, antifreeze should be replaced every 2 years or approximately 40,000 kilometers. Some luxury cars may have extended intervals, with antifreeze replacement cycles reaching up to 10 years or 200,000 kilometers. For vehicles that run for long periods, such as taxis, an annual replacement is sufficient.
