What Are the Consequences of Not Changing Antifreeze for Five Years?
1 Answers
If antifreeze is not changed for five years, its boiling point may rise while the freezing point drops, and it may accumulate numerous impurities. The consequences could include antifreeze boiling or clogging the engine's water passages, leading to reduced engine performance and a shortened engine lifespan. Coolant, also known as antifreeze coolant or simply antifreeze, prevents the coolant from freezing in cold weather, which could otherwise crack the radiator or damage the engine block. Antifreeze is not just for winter use; it should be used year-round. As part of regular vehicle maintenance, engine antifreeze should be replaced every year. Antifreeze Replacement Cycle: According to the vehicle's user manual, antifreeze is typically replaced every two years or approximately 40,000 miles. Different manufacturers may have varying recommendations for the coolant replacement cycle. Functions and Uses of Antifreeze: Antifreeze prevents scale buildup, which can adhere to the metal surfaces of the radiator and water jacket, reducing cooling efficiency and being difficult to remove. High-quality antifreeze is made with distilled water and contains anti-scaling additives, not only preventing scale but also removing existing deposits. Corrosion Prevention: Engines and their cooling systems are made of metals such as copper, iron, aluminum, steel, and solder. Over time, these metals can corrode when exposed to high temperatures and water. Antifreeze not only avoids causing corrosion to the engine cooling system but also provides anti-corrosion and rust-removal functions. In winter, low temperatures can affect vehicle operation. To ensure the car remains functional in cold weather, engine coolant contains substances that lower the freezing point of water, preventing the cooling system from freezing in low temperatures.
