How to maintain the car after a long journey?

By this time, you and your family have already driven back, and life is busy again. However, whether you come back from surfing in the warm south or driving back to your hometown in the north to enjoy the snow, please have a physical examination and maintenance for your car after a long drive this weekend. The following information, if any, please take your seats accordingly.

1, my hometown is not in a big city. I walked a lot on the gravel road home.

Some car owners will drive their cars back to their hometown for the New Year, and most of them are ordinary cars, not off-road vehicles, and there are no tires equipped with off-road vehicles. However, the road home is tortuous. If you drive to your hometown, you must take the hard roads, such as mountain roads and gravel roads, or your hometown is repairing expressway, and the road has not been cleaned. If this is the case, please pay attention to the following tips. Maintain key tires

Maintenance tip: care about your car tires. Usually, the city roads you take have limited wear on tires, but if your car is not an off-road vehicle, you will wear more tires if you run on rugged roads for a few days. Automobile tires will be marked with wear marks on the sidewalls before leaving the factory, which is indicated by the symbol "",which is an alarm sign of tire wear. Generally, after a long journey, we can first visually check the wear marks to see if the four tires have reached the wear limit. If there are no problems with the patterns and wear marks of the four tires, and there is no deviation and abnormal jitter when driving, then you can safely continue driving.

In addition, during high-speed driving, the tire temperature will also increase with the increase of vehicle speed and distance. The characteristic of rubber is that the higher the temperature, the softer the texture. At this time, if there are hard stones or sharp hard objects, it is easy to pierce the tires, and the consequences are unimaginable. If your tire is punctured on the mountain road, repair it casually in the local area. After returning to the ear, it is best to go back to the 4S shop for professional inspection, so as not to affect the driving safety. In addition, tire pressure is also worthy of attention. The tire pressure will definitely change after driving for a long time. In most cases, insufficient air pressure will increase the burden on the engine, increase fuel consumption and easily puncture the tire.

2. Go to Hainan for warm surfing during the Spring Festival.

When it's cold, everyone always runs to a hot place. Miss Deng's family drove to Hainan on the second day of the Lunar New Year. The warm climate there is the best "scenery", but because the climate is too warm, it will also be attacked by insects at high speed.

Maintenance of key paint surfaces

Maintenance tip: Although it is winter, cars heading south will encounter bugs at high speed. When bugs hit the windshield and the front hood, and then exposed to the sun at the seaside in Sanya, the bodies of bugs or bird droppings falling from trees will firmly adhere to the car paint, forming traces. If it is not cleaned or treated in time, it will invade the car paint and become more and more difficult to treat. I suggest you go to a good car wash shop for cleaning at the first time. After a long time, it must be waxed to remove it.

You must clean your car immediately after you come back from a long journey. In addition to bugs, dirt, dust and animal droppings on the road will do great harm to car paint. If it is not treated in time, the paint surface will lose its luster more easily. When washing the car, you should also pay attention to the fact that leaves, dust and dirt can easily attach to the drain hole of the cooling system or the engine compartment cover. If the dirt is not cleaned in time, it will reduce the working efficiency of the cooling system and cause mechanical failure. Therefore, individuals who wash cars should pay attention to these parts and clean them thoroughly with high-pressure air and water. Waxing and painting are also good if possible.

The whole family went to Gordon, Roy, expressway and Shanlu for a long time.

During the Spring Festival, many people drive to tourist attractions. For example, Mr. Wang asked several good friends to drive to Jingdezhen and Huangshan. Driving at high speed for nearly 19 hours is also very enjoyable. However, this kind of Panshan highway needs to step on the brakes for a long time, and the long driving time at high speed is also a test for the brake pads. Maintenance of key brake pads

Maintenance tip: Long-term high-speed driving, frequent braking on mountain roads and use in high-temperature environment are all important factors that aggravate the wear of brake pads, so car owners who run on mountain roads and at high speed during the Spring Festival holiday must check the braking system when they come back. Everyone can understand that you should step on the brakes on mountain roads. Why do high-speed brakes wear for a long time? This is because there have been many brakes during long-distance driving. The higher the speed, the higher the temperature of the brake pad, which will deform it to varying degrees, thus the braking effect and wear will increase accordingly. Therefore, it is recommended to focus on checking the thickness of brake discs/pads and whether they work normally when returning from travel.

There are three steps to check the braking system: first, listen to the sound when braking, and see if there is any abnormal sound; The second is to feel whether the braking force is sufficient and whether the height when stepping on the brake pedal is significantly different from that of a new car. Generally, the brake with severe wear will obviously feel the pedal position is low during emergency braking; The third is to refer to the time and mileage of the last brake pad replacement. Generally, the brake pads of manual transmission models should be replaced every 50,000 kilometers, and the automatic transmission models can be advanced to more than 30,000 kilometers. However, this mileage is not an absolute reference standard, and the wear state has a great relationship with the driver's driving habits.

I have to add low-grade gasoline to run a long distance.

Since it is a long trip, it can't compare with home. You can choose Sinopec or BP when refueling. In expressway, in a strange place, it is good that your car has gasoline. Sometimes you just have to bite the bullet and refuel. Originally, you added 97, but if you don't, you have to "take" 93.

Maintenance of key oil circuit

Maintenance tip: car owners who often travel long distances should know that the oil products in different regions are different. It is almost impossible to have 97 # gasoline in many remote areas. Many car owners should have added 97 # gasoline, but they can barely add 93 # gasoline, or they have to add it when they meet a very irregular gas station. In this case, after returning from a long distance, the engine and oil circuit must be cleaned. Because the direct harm of using low-grade gasoline in high compression ratio engines is carbon deposition, if too much carbon deposition will directly lead to engine scrapping, so owners with the above conditions should clean the engine at the first time.

If there are impurities stuck in the gasoline filter or fuel injector, it will cause faults, resulting in unstable idle speed, weak acceleration, difficult start and other symptoms. If this happens, it is suggested to replace the gasoline filter and clean the nozzle according to the condition of the car to keep the car in the best condition.
