Automobile maintenance is mandatory for every vehicle that reaches a certain number of kilometers after the inspection, adjustment, lubrication, the purpose is to ensure that the vehicle performance is intact, safe and reliable work, the lowest operating costs. Maintenance is divided into a first, second and third level, automobile maintenance operations (generally 1500 to 2000 kilometers) is to clean, lubricate, fasten the main, and check the brake, manipulation and other safety components, according to the specified torque fastening automobile exposed part of the bolt, nut, according to the lubrication of various brands of automobiles lubrication table add lubricating oil (grease), check the lubricating oil surface of various assemblies, cleaning of various filters, in order to maintain the automobile intact technical condition and working ability, and improve the operating conditions. In order to maintain the perfect technical condition and working ability of the automobile, improve the running condition and ensure the safety of driving. Automobile secondary maintenance, customarily referred to as the second maintenance. (Generally 8,000 to 12,000 kilometers is to check and adjust the center, in addition to the implementation of the first level of maintenance operations, but also need to replace the three filters (i.e.: oil filters, fuel filters and air filters), inspection and adjustment of the engine, the braking system and electrical equipment, tire shifting and so on. This part of the work is more specialized and is usually carried out by professional maintenance workers. Level maintenance is a more comprehensive test, through which it exposes and solves the existing faults, to ensure that the various parts of the car and the performance of the whole car in a normal state, and its maintenance of the car plays a very important role. But usually the most easily encountered problem is that the mechanic tends to replace only the three filters, replace the oil, perfunctory scribble check, which is far from the requirements of the second level of maintenance. The car's three-level maintenance to disassemble the assembly, and its cleaning, inspection, adjustment, eliminating hidden dangers as the center, in addition to the second level of maintenance, should be more in-depth cleaning and inspection, and depending on the need to dismantle and inspect the various assemblies or combinations of parts, to eliminate faults, and to remove the accumulation of carbon, oil and caking. Clean the oil passages, remove scale, clean the oil pan and fuel tank, disassemble, inspect and adjust the chassis assemblies, and clean and change the oil, check and adjust the four-wheel alignment, and inspect, descale and paint the frame and body. These operations should be carried out by professional maintenance workers.
Tertiary maintenance has been de-emphasized, and its operational content is basically included in the scope of the assembly overhaul, can refer to the relevant provisions of the assembly overhaul. The three-tier maintenance system has been changed to a two-tier maintenance system, from the past repair-oriented, to maintenance-based, emphasizing the vehicle maintenance system to implement the safety first, prevention-oriented approach, advocate? Seven points of maintenance, three points of repair. No longer require regular dismantling and repair of assembly parts. Warranty is a car manufacturer, for the newly purchased vehicles within the specified period of time for sudden accidents to repair, in order to that preventive inspection (walk warranty), at present, China's domestic new car manuals marked on the warranty period of most of the 2 years or 50,000 kilometers or so, driving years and mileage as long as there is a more than even if it is over the warranty period. "50,000 kilometers on the new car is a threshold, after 50,000 kilometers of the engine, transmission, air conditioning, transmission braking system, etc. If there is a problem may be exposed, the cost of repair is less than thousands of dollars, more than tens of thousands of dollars."
