What Causes a Car to Lack Antifreeze?
2 Answers
Reasons for a car lacking antifreeze: 1. When the water temperature rises, the steam inside the water channel forces the antifreeze out of the replenishment tank; 2. Poor performance of the water pump or thermostat can cause high water temperature in the circulation system, leading to excessive pressure in the radiator and cooling system, which then causes the antifreeze to flow out from the replenishment tank; 3. A poorly sealed cylinder gasket. It is recommended to regularly inspect all sealing points and their connections, and avoid reusing leak-proof gaskets or tapes. The full name of antifreeze is antifreeze coolant, which is a type of coolant containing special additives. Antifreeze has excellent properties such as preventing freezing in winter, boiling in summer, and protecting against scale and corrosion throughout the year.
Having driven for over a decade, I've encountered several instances of coolant loss, most commonly due to aging hoses or cracks in the radiator causing leaks. During summer heat, pipes are prone to cracking, allowing coolant to slowly leak out. Worn water pump seals can also lead to leaks. Ignoring this may cause engine temperatures to skyrocket, potentially resulting in costly damage. I recommend making it a habit to check the expansion tank level when the engine is cold each month, ensuring it stays between the min and max marks. Don't underestimate this simple practice—it can also prevent engine overheating and breakdowns. Additionally, air bubbles in the system can cause fluid levels to drop, so remember to replace the coolant regularly to maintain its effectiveness. Safety first—addressing issues early saves both peace of mind and money.
