How Often Should Coolant Be Replaced in a New Car?
2 Answers
Automotive coolant generally needs to be replaced every two years or every 40,000 kilometers. Since driving conditions vary for each vehicle, the specific replacement interval can be determined based on actual usage. Below are the functions of automotive coolant: 1. Coolant prevents the freezing of the liquid in the cooling system during cold winter parking, which could otherwise cause the radiator to crack due to expansion. 2. Coolant offers excellent performance in preventing freezing in winter, boiling in summer, and resisting scale and corrosion throughout the year. 3. Coolant circulates through the engine's water passages and the radiator, aiding in engine cooling. Below are precautions for adding coolant: 1. When adding long-life coolant, check by opening the radiator cap after the engine has been running for a while. 2. Add coolant slowly; avoid pouring it in too quickly. 3. When adding water, ensure it does not spill onto the engine. 4. Avoid direct contact with coolant. 5. Do not mix different types of coolant.
Since I bought my new car, I've been paying close attention to it, especially when it comes to coolant—you can't just change it randomly. New cars usually come with long-life coolant, which is of excellent quality. The manufacturer says it typically lasts 3 to 5 years without issues. My own car went four years before its first coolant change, mainly because the owner's manual recommended checking it every 50,000 kilometers. Coolant is primarily used to prevent engine overheating or freezing in winter. If it degrades, it can corrode the cooling system, leading to costly repairs. When driving, always keep an eye on the coolant's color—if it turns cloudy or the level drops, address it early. For beginners, I suggest not rushing to replace it. First, check the manual and have a mechanic test its concentration regularly to avoid unnecessary expenses.
