How often should antifreeze be replaced at the longest interval?

[DiOlivia]

Antifreeze should generally be replaced every approximately 40,000 kilometers or every 2 years at the longest. Antifreeze primarily serves two main functions: one is to prevent the water inside the radiator from freezing, and the other is to provide cooling. Therefore, it is recommended that vehicle owners adhere to the manufacturer's guidelines for replacement. Precautions regarding antifreeze: 1. During vehicle use, it is advisable for owners to regularly check the remaining level of antifreeze and replenish it promptly if it falls below the normal indicator line. 2. When entering winter or seasons with lower temperatures, it is recommended to switch to an appropriate antifreeze type, ensuring that its freezing point is 15 to 20 degrees below the local minimum temperature to effectively prevent the vehicle's cooling system from freezing.
