The mileage of this car has reached 60,000 kilometers. What items do you need to do for major maintenance?

60,000 km in 2 years and 65,438+10,000 km in 3 years. The new car has passed the warranty period. Should we go to the repair shop or the 4S shop for maintenance? Recently, the author interviewed 25 car owners who passed the warranty period, and only 20% car owners chose to go back to the store for maintenance. Car owners generally believe that 4S stores charge high fees but have poor technology, and comprehensive stores offer favorable prices but lack services. Insiders said that where to go for maintenance mainly depends on the condition of the car. Go to a 4S shop or a professional large-scale maintenance shop for major repairs, and minor repairs can be solved in a general store. After driving for 3 years or 60,000 kilometers, the shelf life of various oils has expired, and some parts are aging, which requires comprehensive overhaul. There are many projects and more money. Let me list them one by one. After reading it, you will spend less money.

The oil of the whole vehicle should be changed, including brake oil, booster oil, gearbox oil and antifreeze. If it is a manual gear, the transmission oil does not need to be changed. If it's an electronic moped, it doesn't need to be replaced because there is no booster oil. The service life of these oils is 3 years or 60,000 kilometers, whichever comes first. At present, many people arrived three years ago, but 60 thousand kilometers have not arrived yet. For example, they only drove 20 thousand kilometers. It also needs to be replaced according to the requirements of the manufacturer. In fact, a delay of about one year has little effect on the car.

Throttle: Generally speaking, it is recommended to clean the throttle at 60,000 kilometers. In fact, many cars need to clean their throttles after 20,000 kilometers. The frequency of this cleaning depends on the effect of the automobile oil-gas separator. Cleaning the throttle and removing the dirty sludge on the back of the throttle can reduce the intake resistance and restore the initial intake speed of the engine, thus obtaining the correct air-fuel ratio, which is conducive to reducing fuel consumption and preventing idling jitter. Transmission oil: Generally speaking, the replacement frequency of manual transmission oil is 40,000-60,000 km, and that of automatic transmission oil is about 60,000-80,000 km. Maintenance-free automatic transmission does not mean that the transmission does not need to change transmission oil. When the car is driving in Beijing, Shanghai, Guangzhou and other big cities, the oil change mileage of the gearbox needs to be advanced appropriately. When commuting in third-and fourth-tier cities for a long time, the gearbox oil change can be delayed appropriately. Generally speaking, the automatic gearbox suggests changing the oil of the circulating machine. Ordinary gravity oil change can only replace a part of the gearbox oil in the oil pan, which is less than 50%, while the oil change in the circulating machine can recover more than 80% of the gearbox oil at one time, which is relatively more thorough.

Timing belt. If the car is a chain, it can be ignored, and the belt needs to be replaced, because the aging of the belt has a great impact on its life besides being stressed all the time. There are no signs before the belt breaks, and even if it is checked, it can't be detected. Once it breaks down, it is necessary to overhaul the engine, and the damage is relatively large. Besides the timing belt, there is also an accessory belt. Generally speaking, two belts are replaced together. The broken accessory belt will not damage the vehicle, but it will break down and cannot continue driving, because the generator will not generate electricity without help.

Tires: Because tires are rubber products, the aging time of rubber is generally about five years, and the service mileage is generally about 50,000 to 70,000 kilometers. It is recommended that 60,000 kilometers check whether the tires have worn to the safety line. If it has worn to the safety line, it needs to be replaced. Brake pads generally need to be replaced according to wear conditions, and three-way catalytic converters, fuel nozzles and air inlets generally do not need to be forcibly cleaned according to conditions. If there is no difficulty in starting, the gasoline filter can be replaced after 90,000 kilometers. The items to be inspected are mainly batteries and tires. Many batteries will break down after three years. In order to prevent accidents caused by misfire, a professional battery detector should be used for testing. If there is no garage, cars will be exposed to wind, rain, sun and rain every day, so tire aging will accelerate. After three years, you need to carefully check whether you can continue to use it to prevent puncture.

Two years and 60,000 kilometers is the transition from the new car stage to the stable stage. Many exquisite car owners will carry out a major maintenance of their cars after two years and 60 thousand kilometers. This maintenance is comprehensive. Places that can't be inspected at ordinary times will be inspected one by one, not limited to three filters and oil. If you want to drive for a long time, the gearbox oil must be changed. The gearbox is much more precise than the engine, and the engine needs regular maintenance. Why is the gearbox not needed? The replacement cycle of gearbox oil is generally 60,000-80,000 km, including maintenance-free gearbox. When changing oil, it is recommended to change oil by machine. The effect of gravity oil change is very poor. Basically, only 60% oil is changed, and there is no significant effect. For example, booster oil and brake oil should also be replaced regularly. You can ask a mechanic to check the moisture content in the oil for you. Once the water content exceeds 3%, it must be replaced, otherwise it will cause great damage to the parts of your car.
