It is rainy in summer, which not only causes inconvenience to riders, but also adheres to dust and other things on the body and chassis. Cleaning and checking the car after the rain, although it is a small effort, it is an essential part of the daily maintenance of the vehicle.

1. Paint protection There are often acidic and sticky substances in rainwater. Long-term rainfall will cause serious damage to the car body. If it is not cleaned in time, the surface of the car will easily rust or even corrode, which will lose its luster and affect the appearance of the car. Therefore, in the season with more rain, it is best to give the car a paint finish. Experts say that the simplest and most effective way to prevent the acid in the rain from damaging the car body is that the car owner can prepare a piece of dry cloth, wipe the car body simply, and then go to the repair shop or 4S shop to wax the car in all directions and polish and seal the glaze once after the weather turns fine.

2. Chassis care The chassis is the part closest to the ground and driving on a slippery road for a long time. The lubricating oil of the car chassis is easily washed away by rain, so that the chassis is more likely to absorb muddy water and dirt, and even make the chassis rust. The part is most prone to rust, and the wheel shell may even be loose and perforated. Serious will endanger the life of the vehicle. Therefore, we must pay attention to the cleaning and anti-rust treatment of the car chassis. Do a chassis anti-rust treatment, anti-rust effect can be maintained for 3 months.

3. Self-check whether the brake fluid is affected with damp. The wet weather during the rainy season will cause a large amount of water to accumulate on the brake fluid cup and enter the brake fluid. If moisture enters the brake fluid, the high temperature generated by the vehicle during braking will evaporate a large amount of water vapor, and the compressibility of the gas will cause brake failure or even failure. The car owner can confirm whether there is a problem with the brake system through three situations: the brake needs to be stepped on deeply, a noise is heard when the brake is stepped on, and the braking distance is longer than before. In one of these three situations, the vehicle will enter the repair The shop checked.

4. Ignition starts on rainy days, car owners often encounter problems that the engine is not easy to start, and sometimes even if they start reluctantly, they are weak. The biggest possibility of this problem is the leakage of electricity from the ignition system due to moisture. In addition, it may be that when it rains, the weather becomes cool, and the hot air sealed in the distributor may condense into water droplets, causing small floods inside the distributor, thus losing the normal ignition function.

5. The headlights are waterproof and foggy. In rainy days, the headlights of the car are prone to water, the brightness is affected, the direction of the headlights changes, and the headlights may be damaged, bringing safety hazards. If there is water mist in the headlights, you can turn on the headlights. After 10 minutes of driving, whether the water mist in the lights begins to disappear, and whether it can completely disappear after an hour; if there is water mist, it is necessary to go to a professional after-sales service station for processing.

6. Wiper maintenance Driving in rainy days, the wiper must keep working, which will inevitably make the wiper undertake more work, and wiper maintenance is also the most easily overlooked link by car owners. If the wiper is damaged and not clean, the driving line of sight will be affected. It is recommended that every time the owner washes the car, in addition to washing the glass, it is best to wipe the wiper with a glass cleaner to extend the life of the wiper.

7. Frequently turn on the air conditioner after the rain. The air outlet of the air conditioner often has a mildew taste. In order to eliminate this taste, there is a simple way to turn on the warm air of the air conditioner to the maximum, and use various air outlet modes in turn for about 15 minutes. When the air conditioner is working, the temperature of the air outlet can reach 40 ℃-50 ℃, so the hot flash air inside can be evaporated to remove mildew. In terms of indoor moistureproof, air conditioning is the best way, even if the weather is cool, as long as the temperature is set, the air conditioning will not reduce the effect of heating, but can increase the function of dehumidification. Once the weather clears up, open the four-door window and let the indoor air convection. The heated car body will quickly remove the accumulated water vapor inside.

8. sound to avoid the tide sound to avoid the tide is also worth noting. When the rainy season comes, the humidity will increase, and there will often be a layer of fog on the surface of CD records, which will cause difficulties in reading discs. It is best to scrub once every once in a while. In order to avoid moisture when installing the CD drive, do not install it under the bottom plate and seat. It is best to install it at a high place on the body, but do not install it on the rear windshield. Excessive temperature will accelerate the aging of electronic components and laser heads.

9. After going to the repair shop for a comprehensive inspection of the heavy rain, no matter whether the vehicle is abnormal or not, it is best to go to the 4S shop for a comprehensive "physical examination". Because some hidden dangers can not be found on the spot, but the potential harm to the car is extraordinary. For example, heavy rain can easily cause some leaves, dust, etc. to adhere to the drain holes of the heat dissipation system or the engine compartment cover. If these dirt is not cleaned in time, the working efficiency of the heat dissipation system will decrease and cause mechanical failure. Therefore, after the rain, look at the position of the air inlet at the separation of the engine compartment and the cockpit and whether there is water in the grooves on both sides of the left and right fenders. If there is water, you can flush the air inlet with clean water and clear the water channel. To ensure the best working condition of the vehicle.
