The first maintenance of the car must be within 5000 kilometers or half a year. The two standards are based on the first come first. In general, the vehicle running between 4000-5000 kilometers is suitable for vehicle maintenance, which is to adapt to the adaptability of various components during the running in period of the new engine, and the speed can be less than 120km per hour during the running in period.
02. Minor maintenance
Time of minor maintenance:
Minor maintenance is required every 5000 kilometers or half a year.
What do I need to do for minor maintenance?
Minor maintenance generally refers to the routine maintenance items done at the time or mileage specified by the manufacturer to ensure the vehicle performance after driving a certain distance. It mainly includes changing oil and oil filter.
1. Change the oil
Changing engine oil is a must for every maintenance. The engine oil can play the role of lubrication and wear reduction, auxiliary cooling and cooling, sealing and leakage prevention, rust prevention and corrosion prevention, shock absorption and buffer for the engine. However, under the harsh environment of high temperature and high pressure in the engine, the shelf life of the engine oil will be greatly shortened and the performance will be greatly reduced, which will not protect the engine over time.
2. Replace the oil filter element
The replacement of engine oil filter element is carried out simultaneously with the replacement of engine oil. The engine oil filter element is like human's "kidney". It filters out the sundries, colloids and moisture in the engine oil and delivers clean engine oil to all lubricating parts. It is also easy to be blocked after a long time.
03. Major maintenance
Time of major maintenance:
The general recommended time for major maintenance is 20000 km or once every two years.
What needs to be done for major maintenance
Major maintenance is based on minor maintenance. In addition to replacing the engine oil and three filters (engine oil filter element, air filter element and air conditioning filter element), other maintenance items will be added, such as replacing the spark plug, cleaning the oil circuit, etc.
1. Replace the air filter element
The air filter element is mainly used to block the dust and particles inhaled by the engine during air intake. If the filter element is not cleaned for a long time, it will lead to dust inhalation in the engine and abnormal wear of cylinder wall. Therefore, it is very necessary to replace the air filter element in major maintenance.
2. Replace the A / C filter element
The function of the air conditioning filter element is similar to that of the air filter element, except that the clean air is delivered to the vehicle, that is, it is very important for the driving environment of drivers and passengers. Not cleaning or replacing the air conditioning filter element for a long time not only pollutes the automobile air conditioner and reduces the performance of the cooling system, but also affects the physical safety of drivers and passengers.
3. Replace the spark plug
Spark plugs are vulnerable parts. The replacement cycle of ordinary automobile spark plugs is about 30000 kilometers. According to the different materials of spark plugs, the replacement mileage is also different: the replacement mileage of ordinary copper core spark plugs; 30000 km; Replacement mileage of yttrium gold spark plug: 50000 km; Replacement mileage of platinum spark plug: 50000 km.
