What Causes Excessive Consumption of Car Antifreeze?
2 Answers
Reasons for excessive consumption of car antifreeze: 1. Cooling system leakage: Pipes or drain plugs in the cooling system may leak. These parts are relatively easy to detect. Once the leaking part is found, simply tighten or reinstall the corresponding component. 2. Damaged radiator cap: The radiator cap contains an air valve and a steam valve. If the radiator cap malfunctions, causing the steam valve to open at too low a pressure or remain constantly open, it can lead to significant loss of antifreeze. In this case, the radiator cap needs to be replaced. 3. Antifreeze not meeting usage standards: Car engines operate at high temperatures. To prevent antifreeze from boiling, its boiling point is generally above 108 degrees Celsius. Inferior antifreeze that doesn't meet the standard will boil and evaporate. It is necessary to use genuine antifreeze. 4. Engine overheating: If the engine frequently overheats, the antifreeze will often boil and vaporize in large quantities, escaping through the radiator cap's steam valve, resulting in antifreeze loss. In this situation, it is necessary to visit a repair shop to check the cause of engine overheating.
Oh, I had a similar issue with my car before. There was always this green sticky liquid on the garage floor where I parked, which really scared me. After checking for a long time, I found out it was coolant leakage. The main purpose of coolant is to protect the engine from freezing in winter and prevent overheating and cylinder burning in summer. Coolant is usually stored in the container near the radiator and water pump. Leakage can occur due to aging and cracked hoses, loose radiator connections, or corroded and failed seals. As for solutions, first check the coolant level and color to see if they're normal. If it's a minor leak, you can temporarily top it up with the same type of coolant, but it's best not to delay repairs. Have a professional mechanic take a look—they can easily locate the leak point using pressure testing tools. I recommend checking it during regular maintenance. It's safer to replace the coolant every two years, rather than regretting it when the engine starts smoking while driving.
