How Often Should Brake Fluid and Antifreeze Be Replaced?

[McEden]

Brake fluid should be replaced every 40,000 kilometers or 2 years, while antifreeze should be replaced every 4 years or 60,000 kilometers. The functions of antifreeze include the following 2 points: 1. Anti-corrosion function: The engine and its cooling system are made of metals such as copper and iron. These metals can corrode over time when exposed to water under high temperatures. Antifreeze not only prevents corrosion in the engine cooling system but also provides anti-corrosion and rust-removal functions; 2. Protective effect: It offers anti-corrosion protection for components of the cooling system, prevents scale buildup, avoids reducing the radiator's cooling efficiency, and ensures the engine operates within the normal temperature range.
