How Long Can the Coolant in a New Car Last?
2 Answers
Under normal circumstances, the coolant in a new car needs to be replaced every two to three years. However, if you choose a higher-quality coolant and there are no leaks in the engine cooling system, the replacement interval can be extended. Additional Information: How to Identify the Quality of Coolant: 1. Smell: Fake products have various pungent and unpleasant odors, while genuine products have little to no strong smell. 2. Texture: Fake coolants that are not smooth and evaporate easily contain low-boiling-point alcohols, which can cause overheating. If there are white solids at the mouth of the packaging barrel, the product feels heavy when lifted, has a rough texture, and no distinctive smell, it is likely a fake coolant processed with industrial salt or brine. 3. Turbidity: Regardless of the color, the product should maintain a certain level of transparency. Cloudy products are not of good quality. 4. Flowability: Compared to pure water, good coolant has slightly higher viscosity.
I've been repairing cars for over a decade, and coolant is the topic I discuss most with car owners. New car coolant typically lasts 3 to 5 years or about 60,000 kilometers. However, its actual lifespan depends on your driving habits and environment. If you're frequently stuck in city traffic with the engine running hot, you might need to replace it in less than 3 years. Those who drive more on highways find it lasts longer. I remember one customer's off-road vehicle - the coolant turned cloudy and bubbly after just two years. Turned out he often drove through deserts, where high temperatures and sand accelerated deterioration. My advice is to check the coolant level and color annually before summer. It should be bright green or pink when fresh - be alert if it turns cloudy or black. Don't wait until there's leakage or overheating to act. Replacing with OEM coolant costs just a few hundred bucks, far cheaper than an engine overhaul.
