Is it normal for antifreeze to decrease in winter?
1 Answers
Antifreeze will naturally deplete over time. However, excessive consumption is not normal and requires the car owner to promptly investigate the cause of the reduction to prevent it from affecting the vehicle's normal operation. If antifreeze levels drop significantly in winter, it may lead to freezing and cracking of the cooling system pipes. In summer, insufficient antifreeze can more commonly cause the engine to overheat, negatively impacting its lifespan. Antifreeze actually serves two main functions: 1. When the engine is running, it circulates to provide cooling and maintain the engine at its optimal operating temperature. 2. During winter, it prevents freezing, allowing it to immediately perform the first function as soon as the engine starts.
