How often should car coolant be added?

[OCaleb]

Car coolant refers to the antifreeze in a vehicle. It is normal to replace the antifreeze every two years or 40,000 kilometers. If the driving environment is harsh, you can also choose to replace the antifreeze every year or 20,000 kilometers. The functions of antifreeze: It can prevent rust and excessive scale buildup that may clog the pipes, and it has anti-corrosion, anti-scale, anti-boil, anti-freeze, and anti-rust properties. Precautions when using antifreeze: 1. Try to use the same brand of antifreeze; 2. Most antifreeze products have a shelf life of two years, so ensure the product is within its validity period when adding it; 3. Avoid diluting it with water. Traditional inorganic antifreeze should not be mixed with water, as it may cause sedimentation and severely affect the normal function of the antifreeze; 4. For vehicles using antifreeze, never directly add tap water—instead, use distilled or deionized water.
