Matters needing attention in autumn car maintenance

Car maintenance has always been a topic of concern to car owners. Let me introduce you to the matters needing attention in autumn car maintenance, hoping to help you!

1 vehicle external maintenance

The weather turned cold, and the solar term of cold dew has passed in a blink of an eye. There is more dew in the morning, and the surface of the car is often wet. If the surface has obvious scratches, it should be painted in time to avoid the scratches from being corroded by moisture. In addition, due to the corrosion of rain and acid in summer and the direct sunlight in summer, the surface of car paint will inevitably be oxidized. When changing seasons, you'd better do a series of beauty maintenance for the surface of your car, from cleaning and polishing to waxing, polishing or coating.

2 tire maintenance

Due to the high temperature in summer, it is necessary to check the tire pressure frequently, and never let the tire pressure be too high, otherwise there will be a danger of puncture; In autumn, due to the relatively low temperature, it is necessary to add air pressure to the tires to keep them within the specified air pressure range. If the tire surface is seriously worn, it is necessary to replace it with a new tire in time and try to replace the tire that has been repaired many times. When the weather is cold, rubber tires become hard and brittle, which reduces the friction coefficient and is easy to leak and puncture. Even if you replace a new tire, you should always clean the impurities in the tire surface pattern and check whether there are scratches and bumps.

3 Check and add each oil.

Checking and changing oil in autumn is to prepare for winter. Some areas are very cold in winter, so it is necessary to consider the fluidity of engine oil and the antifreeze ability of coolant. Check the condition of engine oil, brake fluid and antifreeze, and replace or add according to the situation. Pay attention to the right amount when adding, and it is not good to have insufficient or excessive oil.

4 Brake system maintenance

Always check whether the brake is weakened or deviated, and whether the pedal force of the brake pedal has changed. If necessary, check or replace the brake system piping and oil.

5 air conditioning system maintenance

The summer weather is hot, the air conditioner runs for a long time, and the condenser and evaporator gather a lot of impurities, which should be cleaned up in time. If the air conditioner filter is too dirty, it should be replaced. Usually, the air conditioner filter is cleaned every 5,000 km or 3 months and replaced every 20,000 km or 12 months. In addition, in order to keep the refrigeration oil circulating, it is best to run the air conditioner 1 time every half month for about 5 min ~ 10 min, even if it is not necessary to turn on the air conditioner.

When the weather turns cold and the temperature is low in autumn, frost will appear. In this season, we should pay special attention to whether the defrosting outlet under the windshield is normal. In addition, it is also important to check the heating system.

6 battery maintenance

In autumn, the electrode connection of automobile batteries is the most prone to problems. If green oxide is found at the electrode connection during inspection, it must be washed off with boiling water. These green oxides will cause insufficient power of the generator and make the battery in a state of power loss. In severe cases, the battery will be scrapped or the car will not be hit.

7 Internal maintenance

Due to the hot and rainy weather in summer, many bacteria breed in hidden places such as carpets and carpets in cars. With the arrival of autumn, the air inside the car will become turbid, and there will be odor, which will cause harm to human health. Therefore, it is necessary to do a thorough internal sterilization and cleaning for your car during the season change. When doing maintenance, it is best to use professional cleaning agent with high-temperature interior sauna machine, which can not only remove dirt and odor in the car, but also effectively kill bacteria. Using protective agent to care for the interior after cleaning can make the interior look brand-new.
