Changing seasons is a “sensitive period” for cars. Many external or internal parts such as circuits, air conditioners, and tires are prone to problems. Therefore,”prevention” and “treatment” are equally important for cars. So what are the points that need to be paid attention to in autumn car maintenance? Let me share with you my experience of car maintenance in autumn.
1. automotive interior
Due to the high temperature and heavy rain in summer, many bacteria and dust grow on the floor and other hidden places inside the car. Once the weather cools down, the car windows are closed, odors and bacteria will pose a hazard to human health. Therefore, it is necessary to do a thorough interior sterilization and cleaning. It is best to use a professional cleaning agent with a high-temperature interior sauna machine, which can not only remove dirt inside the car, but also effectively kill bacteria.
2. automotive exterior
Due to the summer wind and rain, especially the corrosion of acidic substances in rainwater and the exposure to strong summer light, car paint surfaces will inevitably be oxidized and corroded. When the season changes, it is best to do a series of beauty maintenance for the surface of your car, from cleaning and polishing to waxing, glazing or coating.
3. automotive air conditioning system
There is a lot of rain in summer, and vehicles often walk on some wading roads, and the lower part of the air conditioner condenser will inevitably be contaminated with sand. Over time, a large amount of sediment and dust has accumulated, seriously affecting the service life of air conditioners. Therefore, during this season, it is necessary to check and maintain the operating status of air conditioners.
4. Tire aspects
Because of the high temperature in summer, the tires generally cannot be inflated too much. Autumn is different. Because the temperature is relatively low, the tire pressure must be replenished and it must reach the specified range. Otherwise, if the tire pressure is too high, the tire will be explosive. If the tire pressure is too low, it will increase driving resistance, and you must also bring a spare tire. At the same time, the tires should also be checked for obvious injuries, scratches, etc. Rubber becomes hard and relatively brittle in autumn and winter, which not only reduces the coefficient of friction, but also makes it easier to leak air and puncture tires.
5. chassis
The maintenance of automobile chassis in autumn focuses on rust removal and tire inspection. On the one hand, the metal materials of the chassis are prone to rust after being burned in the rainy season or high temperature weather, which hinders driving safety. Therefore, the chassis must be derusted and the chassis must be checked for any phenomena such as peeling screws falling off.
6. engine compartment
Check the oil, brake fluid and antifreeze in the engine compartment while changing seasons, and add them in time to ensure normal operation of the vehicle. If the antifreeze has deteriorated, or the concentration is not enough, or water was originally used, it must be replaced with standard antifreeze before winter, and the antifreeze must be ensured to meet the requirements. Especially before traveling, you must check all kinds of oils, especially lubricants. Because even when driving normally, the vehicle may switch between starting and stopping up to about 18,000 times a year. During long-distance driving travel, your car will definitely encounter frequent starts, stops, starts and stops, causing the engine to be in a long-term state of deceleration, acceleration, and idle, which will aggravate the wear of your engine. These metal debris that falls off the surface of key engine components will continue to wear the engine and cause permanent damage to the engine.
