The rise in temperatures in the past two days has made everyone feel the arrival of spring, but while car owners are busy with daily work and driving leisure, don't forget to provide seasonal maintenance for their vehicles. Auto repair experts said that in fact, cars are like the human body. When raising cars, you can treat them as your own body. The respiratory system, skin, etc. must be checked. Listen to the advice of auto repair experts.

■ Appearance

In spring in the north, the wind and sand are surprisingly strong. In addition, small rocks splashed when cars are driving at high speed and insect liquid common in summer can cause damage to car paint. In addition, the acidic components in rainwater have a very strong corrosive effect on the paint surface of cars, which will cause damage to the paint surface of cars over time. Therefore, in spring when there is more rain, seasonal maintenance must not ignore the waterproofing of cars. When carrying out seasonal maintenance, it is best to paint and beautify your car. What is longer and more effective is to apply glaze and beauty treatment, which will give the vehicle an invisible protective coat.

According to reports, the brightness and hardness of the car paint after sealing will be greatly improved, and the car can take on a completely new look. Therefore, maintenance experts unanimously recommended sealing glaze, which has a very obvious effect. It can keep the car paint smooth and bright, and can also prevent acid rain from corroding the car paint.

■ Interior

Car owners rarely open windows for ventilation in winter, which causes a large number of bacteria to accumulate in the car. Spring temperatures rise, coupled with the humid air, are the season when various bacteria thrive and grow. Therefore, special attention should be paid to the anti-bacterial work in the car interior to keep the car interior dry and hygienic. Especially for sanitary dead spots such as car cushions and air outlets, it is necessary to clean up the car interior environment dry and tidy.

Maintenance experts said that, first of all, the car can be "steamed into a sauna". High-temperature steam can remove stains on the corners of air conditioning vents, seats, interiors, etc., and can also remove the odor inside the car. Then, use a special interior cleaning agent to clean and disinfect the console, doors and other parts.

Maintenance experts remind car owners that when cleaning the interior of the car, they should use a neutral washing solution to clean it. Never use substances containing strong acid and alkali properties to clean it. In addition, when cleaning, attention should be paid to avoid audio, radio, CD and other electrical equipment is corroded by water.

■ Air filtering

The air filter of a car is equivalent to the human nose. It is the first "barrier" that air must pass through when entering the engine. Its function is to filter out sand and some suspended particulate matter in the air, so that the air entering the engine is relatively pure. Only then can the engine work normally. In spring, the air contains more dust and fine sand grains, and the air filter can easily be blocked. At this time, the engine will appear symptoms such as difficulty in starting, weakness, and unstable idle speed. Generally, the air filter of a car needs to be changed every 20000 kilometers, inspected every 10000 kilometers, and it is best to inspect every 2000 kilometers in spring, which is good for the engine.

In addition, after a cold winter, the testing of chassis and tires cannot be neglected. It is necessary to carry out a comprehensive cleaning of the chassis and a comprehensive inspection of the car tires. Especially for four-wheel-drive SUVs, four-wheel positioning should be carried out, because its working condition will directly affect the safety and fuel economy of the vehicle.
