What is the replacement interval for antifreeze?

[Manuel]

Antifreeze should be replaced every 2 years or 40,000 to 60,000 kilometers. Prolonged failure to replace it will degrade the quality of the antifreeze, reducing its anti-corrosion properties and potentially damaging the radiator and pipes. The functions of antifreeze are: 1. To provide freeze protection for the engine in low-temperature environments; 2. To prevent the coolant from freezing and cracking the radiator or damaging the engine block and cylinder head during cold winter parking; 3. To offer efficient heat dissipation. The steps for replacing antifreeze are: 1. Open the car hood after the engine has cooled down; 2. Remove the antifreeze reservoir cap; 3. Lift the vehicle and open the radiator drain plug to release the old antifreeze, then reinstall the drain plug; 4. Lower the vehicle and pour new antifreeze into the reservoir.
