Automotive belts these days last quite a bit longer than they once did, thanks to better materials used in the manufacturing process. Just the same, they’re not going to last forever. So if you’re wondering, “How long should belts in a car last?” that’s a perfectly reasonable question. At some point, you will have to replace a belt, and ideally, you want to do it before it fails.
汽车皮带持续多长时间？
In order to get an accurate assessment of how long your car belts are likely to last, you really should have a hands-on inspection done by a qualified mechanic, but you might be able to get a ball-park idea by providing the model, age, and mileage on your car. It would also be helpful if you know when the belt you’re concerned about was last replaced.
如果您担心皮带，则可以进行视觉检查。有些事情，例如裂缝，磨损，缺少的块或可见的玻璃，证明了皮带需要更换。另外，如果皮带被油或油脂污染，则肯定应该更换 - 皮带将恶化。
If your vehicle is equipped with v belts, they should be replaced within 3 years, or 40,000 miles. Beyond this point, car belt life will be dramatically reduced.
How often should belts be replaced?
Most cars today actually operate using a single belt, called a serpentine belt. Generally speaking, you should replace it every 3 years – more often if you notice wear or missing teeth – unless it’s made from EPDM (ethylene propylene diene monomer). This compound has been in use since 2005, and belts made from it are frequently found in newer vehicles. They’re usually good for 10 years or 150,000 miles. Even so, don’t neglect your car belt maintenance. It’s still a good idea to have a mechanic check the belt from time to time. Usually they’ll do this as a courtesy if you’re in for an oil change or other servicing.
Although replacement recommendations are usually based on years or mileage, the conditions your vehicle is subjected to can also affect the life of the belt. For instance, if you’re constantly driving through water, or if you live in an area where the weather is extreme (freezing in winter or in the triple digits in summer), this will lower the life expectancy of your belt.
因此，请确保正确保持皮带，并在需要时更换。破裂皮带的后果可能很昂贵，预防始终比修复更可取。
