When Should the Coolant in a New Car Be Replaced?
2 Answers
Automobile coolant generally needs to be replaced every 2 years or 30,000 kilometers, while for commercial vehicles, it should be replaced annually. Here are some details about car coolant: 1. The full name of automobile coolant is antifreeze coolant: Its main functions are to remove excess heat from the engine cooling system, prevent the cooling water in the pipes from freezing and cracking the radiator in winter, and protect the engine block from freezing. Additionally, it has waterproof and anti-corrosion properties. 2. There is a significant temperature difference between the north and south: Generally, it is recommended to use -45-degree coolant in the north and -25-degree coolant in the south.
As a new car owner, I didn't even think about coolant in the first year after buying my car. Then my friend's engine got ruined after not changing it for over two years! It turns out that while new car coolant may claim to last 5 years or longer, actual usage conditions matter. For someone like me who frequently drives on highways, the additives deplete faster. If not replaced, the liquid turns cloudy and loses its anti-corrosion properties, risking freezing in winter or overheating in summer. Generally, it's recommended to check the manual and replace every 5 years. DIY is simple too—just pop the hood to check the level and color. Clear is good; if it's dark or has sediment, change it immediately. A quick glance during annual maintenance can prevent major issues. Safety first—don't wait until there's a leak or engine failure to regret it, as repairs start at thousands. Don't slack on new car maintenance; build good habits early.
