What Causes Antifreeze to Boil?

[DominicRose]

Antifreeze boils due to the following reasons: 1. Insufficient or deteriorated antifreeze; 2. Malfunctioning water pump or thermostat; 3. Faulty operation of the electronic fan at the front of the engine. The full name of antifreeze should be antifreeze coolant, meaning a coolant with antifreeze properties. Antifreeze prevents the coolant from freezing and expanding in cold winter conditions, which could crack the radiator or damage the engine cylinder block or head. Precautions when using antifreeze: 1. Try to use the same brand of antifreeze; 2. Most antifreeze products have a validity period of two years, so ensure the product is within its validity period when adding; 3. For vehicles using antifreeze, never directly add tap water; instead, use distilled or deionized water.
