Can Water Be Added to a Car Radiator?

[VonKatherine]

Water can be added to a car radiator, but it is not recommended. Adding water for a long time can corrode the radiator. Also, never add tap water, as it easily forms scale, which is highly harmful to the car. Scale significantly reduces the thermal conductivity of the coolant, causing the engine temperature to rise and corrosion to worsen, further promoting scale buildup and creating a vicious cycle. Steps to add water to a car radiator: 1. Open the engine switch under the driver's seat; 2. After opening, the radiator is located on the right side—push the hood latch inward; 3. Open the radiator cap and add clean water to the appropriate level; 4. Close the radiator cap and shut the hood.
