Mastering certain car maintenance knowledge is the basic skill of the car owner. In daily life, we will find that, as the driving age is extended, everyone's understanding of car maintenance will be deepened, and many problems can be discovered in time. solve. First, how often does the oil change the common oil change? How many oils need to be replaced each time? The replacement cycle and dosage of the oil is a special concern for everyone. The most direct way is to check your own on-board maintenance manual. The above is generally clear. Introduction. However, there are also many people's maintenance manuals that have long since disappeared. At this time, you should know more about it. Generally speaking, the replacement period of the oil is 5000 kilometers. The specific replacement cycle and dosage should be judged according to the vehicle related information. Not all models are suitable for owners to change their own oil, but we can learn to check the oil gauge to determine if the oil has arrived. Also, the oil filter must be replaced while changing the oil. Second, antifreeze use common sense Antifreeze is best used throughout the year, in addition to the function of antifreeze cooling, antifreeze also has the role of cleaning, descaling, anti-corrosion, reduce the corrosion of the water tank, protect the engine. Note that the color of the antifreeze should be picked correctly and not mixed. Third, the brake oil use common sense Brake system function and brake oil have a close relationship, when checking the replacement of brake pads, brake discs and other hardware, do not forget to see if the brake oil needs to be replaced. Fourth, the transmission oil In order to ensure the car steering flexibility, always check the transmission oil, whether it is gear oil or automatic transmission oil, pay attention to the type of oil, usually it is high. Maintenance items What are the daily car maintenance items? The car is a very complicated and large machine. In the operation, the mechanical parts will inevitably wear out, and the external man-made and environmental factors will cause the loss of the car. According to the driving condition of the car, the manufacturer will formulate corresponding car maintenance items. What are the common maintenance items? Item 1、Small maintenance and small maintenance content: Small maintenance generally means that after the car has traveled a certain distance, in order to ensure the performance of the vehicle. Regular maintenance items made by the manufacturer's time or mileage. Mainly includes the replacement of oil and oil filter. Small maintenance intervals: The small maintenance time depends on the effective time or mileage of the oil and oil filter used. The expiration date of mineral oil, semi-synthetic engine oil and fully synthetic engine oil of different brand grades is also different. Please refer to the manufacturer's recommendation. The oil filter is generally divided into two types: conventional and long-acting. The conventional oil filter is replaced with random oil, and the long-life oil filter is used for a longer period of time. Small maintenance items: 1. The oil is the lubricating oil for the engine. It can lubricate, clean, cool, seal and reduce the engine. It is important to reduce the wear and tear of engine parts and prolong the service life. 2. The oil filter is a component of the filter oil. The oil contains a certain amount of colloid, impurities, moisture and additives; during the working process of the engine, the metal scrap generated by the friction of each component, the impurities in the inhaled air, the oil oxide, etc., are the objects of the oil filter. If the oil is not filtered, entering the oil circuit directly will have an adverse effect on the performance and life of the engine. Project 2, big maintenance The content of the big maintenance: The large maintenance refers to the time or mileage specified by the manufacturer, and the contents are the routine maintenance of replacing the oil and oil filter, air filter and gasoline filter. Interval for large maintenance: Large maintenance is based on the presence of small maintenance, which is generally performed alternately. Intervals vary by car brand. Please refer to the manufacturer's recommendation. Large maintenance items: In addition to changing the oil and oil filter, there are two items in the car maintenance: 1. The air filter engine should suck in a lot of air during the work, if the air does not pass through Filtration, where the dust accelerates the wear of the piston block and cylinder. Larger particles enter between the piston and the cylinder, which can also cause severe "cylinder" phenomena. The function of the air filter is to filter out dust and particles in the air to ensure that the cylinder enters a sufficient amount of clean air. 2, gasoline filter The role of the fuel filter is to provide clean fuel for the engine, filter out the moisture and impurities of the gasoline. This optimizes engine performance while also providing optimum protection for the engine. Usually, when performing car maintenance, the operator will perform other inspections according to the specific conditions of the car, and other maintenance items, such as inspection and maintenance of the engine-related system, positioning of the tires, inspection of various fastening components, and the like.
