Do I Need to Add Antifreeze Myself?

[VonCody]

Antifreeze needs to be added by yourself. Under normal circumstances, it should be added every two years or 40,000 kilometers. Its function is to prevent the coolant from freezing during cold winter parking, which could cause the radiator to crack or damage the engine cylinder block or head. The method for replacing antifreeze is: 1. Unscrew the radiator cap and open the radiator drain valve to release the antifreeze; 2. Run the engine at idle speed and inject clean water until the radiator discharges clear water; 3. After the clean water has completely drained, close the drain valve; 4. Add new antifreeze until the liquid level is between the MAX and MIN marks; 5. Close the cap and let the engine idle for two to three minutes. Precautions for using antifreeze include: 1. Try to use the same brand of antifreeze; 2. Ensure it is within the validity period when adding; 3. Avoid diluting it with water; 4. If a large amount of particle precipitation appears, it indicates the antifreeze has deteriorated and should no longer be used.
