What Causes a Car's Antifreeze to Be Low?

[Ramon]

Car antifreeze may be low due to the following reasons: 1. Radiator damage or poor sealing of the upper and lower water chambers; 2. Loose connections and poor sealing at the overflow tank, water pump mating surface, or cooling system pipelines; 3. Damaged cylinder head gasket; 4. Warping at the joint between the cylinder head and engine block or loose cylinder head bolts. The functions of car antifreeze include: 1. Providing freeze protection for the engine against low-temperature environments; 2. Preventing coolant from freezing and cracking the radiator or damaging the engine block and cylinder head during cold winter parking; 3. Offering efficient heat dissipation. Car antifreeze should be replaced approximately every 2 years or 60,000 kilometers. Prolonged failure to replace it can degrade the antifreeze's quality, reducing its anti-corrosion properties and potentially damaging the radiator and pipelines.
