Can You Directly Top Up the Car's Antifreeze When It's Low?

[VivienneMarie]

You can directly top up the car's antifreeze when it's low. If the antifreeze loss is within a reasonable range, you can add it yourself, but you should use the same brand of antifreeze. Different brands of antifreeze use different metal corrosion inhibitors, so antifreeze from different brands should not be mixed. The main functions of antifreeze are to prevent freezing and provide cooling, with characteristics of a very high boiling point and a very low freezing point, making it ideal for use in a car's engine. Most antifreeze products have a validity period of two years. When adding, ensure the product is within its validity period. When replacing, drain the old antifreeze completely, clean the cooling system thoroughly, and then add new antifreeze.
