What to Do If Water Is Added to Coolant?

[RyderLee]

Solution for adding water to coolant: Adding a small amount is fine and does not affect its performance. However, if the amount of water added exceeds one-quarter of the coolant's total capacity, it will impact its effectiveness. In such cases, the coolant needs to be replaced entirely; otherwise, it may cause damage to the engine. Adding water to coolant may reduce its performance, thereby increasing the risk of engine failure. Coolant, also known as antifreeze coolant, prevents freezing during cold seasons, which could otherwise crack the radiator or damage the engine cylinder block. Antifreeze is not just for winter use—it should be used year-round. As part of regular vehicle maintenance, the engine coolant should be replaced every year.
