What Type of Water Should Be Added to a Car Radiator?

[AnnieRose]

Select antifreeze based on the vehicle's origin. Generally, antifreeze for domestic vehicles and imported vehicles cannot be mixed. Therefore, when purchasing, choose the appropriate antifreeze according to your vehicle's origin. This is because the rust inhibitors, defoamers, and dyes in imported vehicles differ chemically from those in domestic antifreeze. Mixing them can trigger chemical reactions, leading to adverse effects such as scaling and corrosion. More details about car radiators are as follows: 1. Frequency of adding water to the car radiator: If the water level in the antifreeze reservoir falls below the minimum mark (normal capacity should be between MIN and MAX), water should be added promptly. The replacement cycle is typically every two years or every 30,000-40,000 kilometers driven. Vehicles used frequently should be replaced earlier as needed. 2. Avoid adding tap water: Tap water tends to boil easily, which makes it unsuitable. Additionally, tap water contains many substances that can easily cause rust and scale buildup.
