How Long Does Antifreeze Expire After Leaving the Factory?

[EmilyLynn]

Antifreeze expires 2~3 years after leaving the factory. Antifreeze replacement cycle: Vehicle antifreeze generally needs to be replaced every 2 years or 40,000 kilometers. This is just a reference cycle. For commercial vehicles with longer mileage, the replacement cycle is shorter. Since driving conditions vary for each vehicle, the replacement should be based on actual usage. Check the antifreeze's condition; if it is insufficient, replenish it promptly. If suspended matter, sediment, or signs of deterioration or discoloration are found in the antifreeze, replace it immediately and clean the system. How to choose antifreeze: The basic indicators of antifreeze are its freezing point and boiling point. On the market, antifreeze comes in several specifications with freezing points of -15°C, -25°C, -30°C, -40°C, etc. Generally, it is advisable to choose antifreeze with a freezing point at least 10°C lower than the lowest temperature in your region. Antifreeze plays a crucial role in the engine's cooling system.
