How Often Should You Add Water to a New Car?

[ODelaney]

The coolant in the radiator should generally be replaced every two years or every 30,000-40,000 kilometers driven. For vehicles with high usage frequency, it is advisable to replace it earlier. Only add coolant; never use tap water, as it tends to boil easily and contains many impurities that can lead to rust and scale buildup. Notes on adding coolant: 1. Choosing coolant: Select coolant based on the vehicle's origin. Generally, coolant for domestic vehicles and imported vehicles cannot be mixed, so it's important to choose the appropriate coolant for your vehicle's origin. This is because the rust inhibitors, antifoaming agents, and dyes in imported vehicles differ chemically from those in domestic vehicle coolants. Mixing them can cause chemical reactions, leading to issues like scaling and corrosion. 2. Diluting coolant: Some coolants need to be mixed with water in specific proportions to be effective. Many car owners use them directly without reading the instructions, which can result in engine overheating. Therefore, no matter what type of coolant you purchase, it's best to read the instructions beforehand to ensure everything goes smoothly.
