【Owner's home car knowledge】The exciting Spring Festival is coming again, and many private car owners choose to bring their relatives and friends home by themselves. You must have had a great time during the long vacation! I believe that all car owners and friends have thoroughly inspected and maintained their cars before the trip. And the number on the odometer of your weather-beaten car that accompanied you all the way is believed to have increased by a lot. Just in time for the Spring Festival to come, it is time to carry out corresponding routine maintenance. So, what exactly should you check for?
1. Check the engine oil
Generally speaking, the lack of antifreeze and engine oil after long-distance driving is a common phenomenon. If you forget the label of the previously added engine oil, do not add new engine oil blindly at this time, because the mixed use of engine oil with different labels may cause adverse consequences. The correct way is to clarify the label of the original engine oil and then choose the same label to add. Of course, if your maintenance period is approaching, then simply drain the original engine oil and add new engine oil.
And if the liquid level of antifreeze is too low, what should we do? Here I want to introduce a common sense to you: ordinary engine antifreeze needs to be replaced every 2 years.
2. Check the components in the engine compartment
Another thing to check in the engine bay is the "air filter". If there is more dust on the way you are driving than in the city, the air filter may absorb too much dust during this period, and if the dust enters the engine, it will cause wear of various parts in the engine; It will cause poor air intake of the engine and a decrease in power. Therefore, it is necessary to remove the air filter and check it.
3. Check the appearance and paint surface of the car body
The appearance mentioned here includes the body surface and all parts that you can see. Although it sounds complicated, it is actually very simple. For example, after long-distance high-speed driving, whether there is any damage to the paint surface of your body (due to high-speed driving, it is inevitable to encounter small stones bouncing on the road surface, which will cause damage to the paint surface). The method is to wash the folded car and then go around your car twice and find the injured part in time.
4. Check the tires
Another point is that whether the tires are excessively worn can also be judged by the naked eye. After long-distance driving, some wheels will have obvious scars, excessive wear or "trauma". At this time, depending on the specific situation, you can choose to replace the spare tire and go to the nearby 4S shop for further inspection as soon as possible. In addition, after a long period of bumping, the positioning of the tires may fail. At this time, the most notable feature is that the vehicle will deviate and jump. If this happens, you also need to go to the 4S shop for inspection.
5. Check the brake system
Visually inspect the surface of the brake disc through the aluminum alloy steel rim of the tire. The surface of the brake disc is originally smooth. If there are obvious grooves, it may be that when the vehicle is driving on a gravel road, some small sandstones are stuck between the brake disc and the fender, and the surface of the brake disc is constantly rubbed, so the grooves appear. . When this happens, the vehicle may make a "clang, clang" sound while driving, and in some cases, the owner may hear a squeal when the brakes are dragged.
6. Check the interior carpet
According to the experience of the technician using the car, if the vehicle passes through some poor roads (such as wading) or encounters heavy rain, flooding, etc., the owner should check whether the vehicle carpet is wet. There are some holes on the car body of some brands that are plugged with rubber. After a long time, due to the decline of the sealing performance of the rubber plug, water will enter the car when the car is flooded or wading. The situation is not serious. However, it may cause mildew and odor in the car.
7. Check whether the chassis is "injured"
The owner can recall whether there is any experience of scratching the chassis during driving. At the same time, compare whether there are obvious changes before and after the car holiday. If there are abnormal chassis noises, steering wheel vibrations, oil stains on the parking position of the vehicle, etc., it means that the chassis has been damaged. This is because road obstacles scratch the chassis, causing some parts of the chassis to deform, especially the upper and lower swing arms, left and right direction tie rods, etc. are prone to deformation. Some minor scratches will also cause slight leakage of the oil pan or the oil pan of the gearbox, and these are problems that the owner cannot detect in time by self-testing. It is recommended to go to the manufacturer for professional chassis anti-rust care or spray paint to make the chassis "armor" once to avoid future troubles.
Eight, check the whole car glass
When it comes to glass maintenance, you must be wondering, what maintenance can glass have besides washing with water? In fact, glass maintenance is very knowledgeable, not all problems can be solved by rinsing with water. For example, after the glass is stained with oil, it may not be visible to the naked eye, but the efficiency of the wiper will be greatly reduced. At this time, you must use a degreasing cleaning agent to remove the grease. There are also those permanent scratches on the windshield caused by the inclusion of sand and gravel in the wiper, and the trauma caused by the impact of stones on the glass. They are not "terminal diseases" for modern car maintenance technology. Advanced materials and technologies These wounds can be polished and repaired.
Through the above 8 preliminary inspections "from the outside to the inside", I believe you will have a more comprehensive understanding of the condition of your car, and the inspection of the engine, brakes and tires is the most critical
