Automobile maintenance refers to the preventive work of regularly checking, cleaning, supplying, lubricating, adjusting or changing some parts of the relevant parts of the automobile, also known as automobile maintenance.

Modern automobile maintenance mainly includes the maintenance of engine system (engine), gearbox system, air conditioning system, cooling system, fuel system, power steering system and so on.


The purpose of car maintenance is to keep the car clean, normal technical conditions, eliminate hidden dangers, prevent failure, slow down the deterioration process, extend the life cycle.




The oil change

How often is the oil changed? How much oil do I need to change each time? On the oil replacement cycle and dosage is a special concern, the most direct is to see their own car maintenance manual, generally have a very clear introduction. But also have many people's maintenance manual already disappeared, at this time you are about to learn more about. Generally speaking, the oil replacement cycle is 5000 km, the specific replacement cycle and consumption should be judged according to the relevant information of the model.


Not all models are suitable for owners to change the oil themselves, but we can learn to check the oil gauge to determine whether it is time to change the oil. Also, oil filters must be replaced when oil is changed.


Two, the use of common sense antifreeze


Antifreeze is best used throughout the year, in addition to antifreeze cooling functions, antifreeze and cleaning, rust, corrosion, reduce the corrosion of the tank, protect the engine. Pay attention to the color of antifreeze to choose the right, do not mix.


Three, brake oil use common sense


The function of the brake system is closely related to the brake oil. When checking the replacement of brake pads, brake discs and other hardware, do not forget to check whether the brake oil needs to be added and replaced.


Transmission oil


In order to ensure that the car steering is flexible, always check the transmission oil, whether it is gear oil or automatic transmission oil, pay attention to the type of oil, usually is high.



Maintenance project

What are the daily car maintenance items? Automobile is a very complex large machinery, in the operation of the mechanical parts will inevitably produce wear, coupled with the external human, environmental and other factors, resulting in the loss of the automobile. According to the driving condition of the car, the manufacturer will formulate the corresponding car maintenance project, what are the common maintenance projects?


Item 1: small maintenance


Minor maintenance:


Small maintenance is to point to the car commonly after driving certain distance, and the routine maintenance project that is done in the time that the manufacturer sets in order to safeguard vehicle performance or mileage. It mainly includes changing oil and oil filter element.


Small maintenance interval:


The time of minor maintenance depends on the effective time or mileage of the oil used and the oil filter element. Mineral oil, semi-synthetic oil and full-synthetic oil of different brand grades have different expiry dates. Please refer to the manufacturer's recommendation. There are two types of oil filter elements: conventional oil filter element and long-term oil filter element.


Small maintenance items:


1, the oil is the engine running oil. It can lubricate, clean, cool, seal and reduce friction. It is of great significance to reduce the wear of engine parts and prolong the service life.


2, oil filter is a filter oil components. Oil contains a certain amount of gum, impurities, water and additives; In the process of engine operation, metal chips generated by friction of various parts, impurities in the air inhaled, oil oxides, etc., are all the objects filtered by the oil filter element. If the engine oil is not filtered and enters the oil circulation directly, the engine performance and service life will be adversely affected.


Project two, maintenance


Major maintenance contents:


Major maintenance refers to the routine maintenance of oil replacement, oil filter element, air filter element and gasoline filter element within the time or mileage specified by the manufacturer.


Big maintenance interval:


Big maintenance is based on the existence of small maintenance, generally these two kinds of maintenance alternately. The intervals are different due to the differences of automobile brands. Please refer to the manufacturer's recommendation for details.


Products for maintenance:


In addition to the replacement of oil and oil filter, there are the following two items in the car maintenance:


1. Air filter


A lot of air is sucked into the engine during operation. If the air is not filtered, the dust will accelerate the wear of the piston assembly and cylinder. Larger particles entering between the piston and the cylinder, will also cause serious "pull cylinder" phenomenon. The function of the air filter element is to filter out the dust and particles in the air and ensure sufficient and clean air in the cylinder.


2, gasoline filter


The function of gasoline filter element is to provide clean fuel for the engine and filter out the moisture and impurities of gasoline. Thus, the engine performance can be optimized and the best protection can be provided for the engine.


Usually, in the car maintenance, the operation staff will do other checks according to the specific situation of the car, will also increase other maintenance items, such as engine related system inspection cleaning maintenance, tire positioning inspection, inspection of the fastening parts and so on.
