Maintenance reason
1. The engine air filter is an important part of the whole car. In rainy days, the air filter is easy to get water. In particular, the air filter of many vehicles is very low from the ground. Once the water enters the road, it may cause serious mechanical accidents, and it is easy to cause the phenomenon of connecting rod bending and cylinder pounding. In this way, the engine at the heart of the car will be scrapped, which will bring unnecessary losses to the owners.
2. The paint surface of the car body is originally to protect the car shell, and the acid composition in the rain water has corrosive effect on the paint surface, which will cause damage to the car body over time. Therefore, in the season with more rain, it is better to maintain the paint surface for your car once.
3. Because the chassis is close to the ground, it is easy to rust, so we must pay attention to the cleaning and anti rust treatment of the automobile chassis. Chassis maintenance is usually done by a professional car maintenance center.
4. Due to the humid weather, it is easy to cause the vehicle ignition system leakage, and the engine is not easy to start.
5. With more rain and high air humidity, the brake fluid of the car is easy to absorb water. If there is water entering the brake fluid, the high temperature generated by friction will make the water gasified during the braking process. But the gas has the compressibility. If it is compressed in the brake fluid, it will cause the brake failure or even failure.
6. The increase of rain in rainy season will inevitably make the wiper bear more responsibilities, and the inspection and maintenance of the wiper should be more careful. If the rain can not be well scraped off by the wiper, it will bring great danger to the driving safety, so the inspection and maintenance of it should be more careful and in place.
7. The rising temperature and humid air in the plum rain season are the seasons for the reproduction and growth of various pathogens. Therefore, special attention should be paid to the sanitation and bacteria prevention of the car interior.
8. The adhesion between the tire and the ground will be greatly reduced due to water, which is why the car is easy to slip in rainy days.
Maintenance skills
Tip 1: engine and exhaust pipe maintenance
When driving, we must pay attention to the depth of water, not reckless. After the vehicle is collected, the rainwater on the engine shall be wiped in time to check whether the generator belt has cracks, so as to avoid shortening the service life of the vehicle. When passing through a place with deep water accumulation, the exhaust pipe behind the car will also be immersed in the water, and the exhaust pipe will be flooded, so the car can't be hit. So when the water is too deep, try to detour. If it can't be detoured, a rubber pipe can be used to connect it to the exhaust pipe, with the pipe mouth facing up, so that the water can't enter the exhaust pipe.
Tip 2: paint protection
A simple and effective method is waxing, and a longer and more effective way is to seal the glaze. Both can prevent the paint surface from fading and aging, so as to protect the car body from damage.
Tip 3: chassis maintenance
The general steps are cleaning first, and then antirust treatment. The whole process takes about 30-40 minutes. Do a chassis antirust treatment, antirust effect can be maintained for 3 months or even longer.
Coup 4: engine circuit moisture-proof
If the engine suddenly stalls in the process of moving, do not ignite and start repeatedly, wait for a while or get off the vehicle to check the circuit, otherwise it is very easy to cause the engine to be scrapped. If it is due to aging leakage, it must be replaced in time. In rainy days, we often wade in water. When the car goes through the water smoothly, we should timely maintain the circuit equipment.
Coup five: brake water removal
Because most of the car brake system is double pipe vacuum assisted hydraulic brake, the brake fluid that transmits the brake force has a strong water absorption. Once it is found that the brake fluid absorbs water seriously, it should be sent to a professional service shop for water removal.
Tip 6: check the wipers in time
If the rain can not be well scraped off by the wiper, it will bring great danger to the driving safety, so the inspection and maintenance of it should be more careful and in place. When the windscreen wiper works, the surface of the glass is in the form of mist and water droplets, and there are stripes or local blurring, mostly due to the influence of oil film, dirt or car wax, as long as the windshield and wiper blade are cleaned. Once the wiper fails to move, the fuse is mostly burnt out. Find the fuse of the wiper and replace it with a new one.
Coup 7: sterilization in the car
Clean the dead corners such as car seat cushion and air outlet, and use special interior cleaning agent to clean and disinfect the console, door and other parts. Pay attention to the protection of audio, radio, CD and other electrical equipment to prevent them from water corrosion.
Tip 8: tire maintenance
Before the rainy season, if the tire is severely worn and the tread disappears, it must be replaced. Some people reduce the tire pressure a little every rainy season, so as to increase the friction area between the tire and the ground, and then increase the adhesion. In fact, the opposite is true. In this way, it is more likely to cause tire slip, and it is very important to maintain the normal tire pressure.
matters needing attention
Avoid being at a loss when encountering problems. Pay attention to regularly check the performance of the car when driving.
The maintenance work that you can't do well by yourself should be solved by 4S shop or auto service company. Don't do it blindly to avoid unnecessary damage.
