Before writing the article, just a friend bought a used car. After a while, he was very satisfied. However, suddenly one morning the car was picking up, and the train could not be started. It can be judged by a friend's description. It should be that the battery was dead. Then, after the replacement of the new battery, the car was all normal. The anxiety of my friend after buying a used car also eased a lot. Through the problem of car use by friends, we can see that many consumers who buy used cars can enjoy the high cost-performance of used cars. Once problems arise in the car, they may worry about the condition of used cars. In fact, the car has a lot of problems. The time is caused by some small details. We usually take care of it, so we can avoid many problems. Car battery will also make you anchor Whether it is a new car or a used car, the car battery is an easily overlooked issue. Many people will say that the battery life of the car is about two years, but from the perspective of the actual car, the car battery life is still very large, Life expectancy also varies from 1 to 5 years. This is mainly reflected in the habit of using cars. Therefore, it is advisable to use a voltmeter to test the life of a battery directly. This is the most accurate method. In addition, if the car starts for a long time, It may also indicate that the life of the battery is approaching. We should change it earlier. Otherwise, we can't tell you that the battery will suddenly strike. Low oil change effect is obvious For some models without maintenance records, we have to carry out related maintenance through the mileage of the car. Under normal circumstances, many people are accustomed to driving after a certain period of time, but from the actual point of view, after we buy used cars, it is best to directly replace the oil filter, the oil directly affects the state of the engine, these costs There are a few hundred, the cost is very low, but if the engine damage caused by not changing the oil is still more serious, some gain is not worth the candle. After replacing the oil filter, we can record the mileage, so that we can know the time of the next maintenance. Transmission oil, brake oil, coolant can be checked and replaced according to instructions Having finished the oil used car, let's look at the maintenance of other oils, if the car travels for tens of thousands of kilometers, then the transmission oil may need to be replaced, and this is also easily overlooked by many consumers, in general, The service life of the transmission oil is 40,000-80,000 kilometers. You need to pay attention to the fact that the automatic transmission oil can't be used wrongly or mixed. Otherwise it will cause parts and components to wear out. Brake oil replacement cycle is changed every two years Brake oil replacement cycle is generally replaced once every two years. The brake oil plays a role in the brake system of the vehicle. The brake oil itself has strong water absorption characteristics. It absorbs the moisture in the surrounding air, such as car wash and humid environment. And so on, the brake fluid has been used for a long time. Although there is not much impact on the surface, when the vehicle is in emergency braking or driving on a downhill road for a long time, the brake system will make the temperature of the brake oil rapid in the long-term or emergency braking process. Rising, directly causing the boiling point of the brake oil to fall, so that the braking force will drop, thereby affecting the performance of the brake. Don't forget to check tire wear Tire belongs to the consumables on the car. Wear and tear are inevitable. Unlike the oil maintenance cycle, the tire life of the car is mainly judged by the pattern of wear. Many people sell tires when the car is sold. Seriously, it will often be used, and some car dealers may use some old tires to replace the newer tires. Therefore, after buying a used car, the degree of tire wear must be carefully observed. If the wear exceeds the warning point, then Should try to replace new tires.
