Car owners communicate with each other, the most talked about topic is car maintenance, some people go to the 4S shop for maintenance, although a little more expensive but more worry-free. Some people go to some small shops for maintenance, or if they have the conditions, they can directly maintain it themselves. The most important item of car maintenance is to change the engine oil, because the engine oil is the most critical factor affecting the life of the engine and must be changed regularly. But in addition to changing the oil, there are a number of checks that need to be done to reduce the risk of malfunctions or safety issues. That is to say, after each maintenance of the car, all parts of the car must be free of potential safety hazards. Many car owners who maintain themselves or go to a small shop for maintenance often change the oil and do not do any inspection, which is an incomplete maintenance process. In addition to changing the oil, what specific items need to be checked?
1. Inspection of all parts of the brake system
It mainly checks the wear of brake pads and brake discs, as well as the aging of brake hoses. For these parts, the owner usually does not check by himself, and only checks by the maintenance technician during maintenance. If the thickness of the brake pads is less than 3 mm, or the thickness of the brake pads is predicted to be insufficient for the next maintenance, then it is recommended that the owner replace them. There is also the inspection of brake discs and brake hoses, brake hoses are rubber parts, which are easy to age after a long time, easy to leak after aging, and even bulge, and then continue to use it will burst out. If it is an old car that is more than ten years old, it needs to be checked.
2. Inspection of tires and bearings
The tire pressure of the tire is the basic check item, and then check the degree of aging and wear of the tire, whether it is injured, and whether there is abnormal wear, because the quality of the tire is very important for driving safety. If the positioning data is incorrect, the tire may be worn by the tire, which can be found and repaired in time through inspection to prevent the tire from being worn out, and there are also potential safety hazards. When the oil is changed, the vehicle is lifted, and you need to turn the wheels by hand to check the smoothness of the wheel rotation to see if there is too much wheel rotation resistance, which may be a problem with the bearing or brake cylinder.
3. Check the lights of the whole car
Some 4S shops still have brake lights that do not light up after completing maintenance, which is actually a taboo for 4S shops and do not fulfill the obligation of inspection. All the lights in the car should be checked, especially the brake lights, because the owner himself does not know whether the brake lights are working or not. Some car owners even have a low beam bulb broken, only one side is bright can not be found in time, and the brake light is not lit will definitely not know, so it needs to be fully checked during maintenance. The quality of the lights is also very important for driving safety, especially the brake lights, which need to be known to the rear car for the first time when braking. Low beams are also very important if you are driving at night, even if there are street lights that do not need to be illuminated, you need to keep both low beams on. If there is only one light, it will be impossible for people in the distance to tell whether it is a motorcycle or a car.
4. Inspection of the chassis
The chassis inspection mainly inspects three aspects, one is to check whether there are bumps and broken parts. The second is to check the aging of each rubber sleeve, whether there is cracking, falling off, etc. There is also whether there is a loose phenomenon in each tie rod and ball head. The third is to check whether there is oil leakage in the engine and gearbox, because it is not easy to see the oil leakage from the top of the engine, and it will be clearly seen from below.
5. Inspection of electronic modules
Finally, it is necessary to use a computer diagnostic instrument to check whether the data flow of each computer module and sensor is abnormal, and check whether the vehicle has fault codes. Now even the computer has to be used to detect the vehicle fault code when the car is reviewed, in order to ensure that the electronic modules are working properly. This step is also essential for inspection during maintenance. Computer detection can find abnormal electronic components, repair or replace them in time to ensure the normal operation of the engine, so that the fuel consumption is at a normal level, the emission also meets the requirements, and at the same time, it can also eliminate potential safety hazards.
In short, car maintenance is not just about changing the oil, but also about doing a comprehensive inspection of the vehicle to ensure that the vehicle can run smoothly and safely during the next maintenance cycle. Eliminate safety hazards through inspections to get your vehicle in the best condition.
