What Causes Car Antifreeze Leakage?
2 Answers
The causes of car antifreeze leakage are: 1. Radiator damage, poor sealing of upper and lower water chambers; 2. Loose connections and poor sealing at the overflow tank, water pump joint surface, and cooling system pipelines; 3. Cylinder gasket damage; 4. Warping at the joint between cylinder head and cylinder block or loose cylinder head bolts. The solutions for car antifreeze leakage are: 1. Replace the radiator; 2. Tighten the screws at the overflow tank, water pump joint surface, and cooling system pipelines; 3. Replace the cylinder gasket; 4. Tighten the cylinder head bolts. The full name of antifreeze is antifreeze coolant, and its functions include: 1. Anti-corrosion; 2. High boiling point; 3. Prevention of scale formation.
I've been driving for twenty years and have seen coolant leaks several times, usually due to cracks in the radiator connections or aging and damage to the hoses. High engine temperatures can soften and crack rubber. I remember last summer when the temperature light on the dashboard came on, I got out and found blue-green stains on the ground. I quickly added distilled water as an emergency measure and went to the repair shop. The mechanic said minor leaks should be fixed promptly, otherwise engine overheating could burn out the cylinder head gasket, leading to a major repair. For older cars, it's best to change the coolant every two years because old coolant is more corrosive and can easily cause component wear. Now, every time I wash the car, I check the cooling system: after starting the engine, I observe the pipe connections and expansion tank for any drips or leaks, and keep the fluid level between max and min. Delaying repairs could cost thousands, so it's better to be careful.
