Car Knowledge School: Car Maintenance in Rainy Season

Key points for car maintenance during rainy season

1. Maintenance of paint surface

The acidic components in rainwater have a corrosive effect on the car's paint surface, which will cause damage to the car's paint surface over time. Damage to the car's paintwork. Therefore, before the summer rainy season, it is best to give your car a paint job and protect the paint.

For example: applying wax or sealing glaze to your car, which can be done according to the actual situation of your car. It is recommended that a new car be sealed once. A good sealing glaze can not only prevent the paint surface from aging, but also prevent rainwater from accumulating on the car.

2. Pay attention to the moisture-proof inside the car

After the rainy day, when the sun comes out, the car should be properly exposed to the sun, and all the windows should be opened to disperse the moisture in the car through the convection of air. of moisture, and let the speaker work for a period of time to better dissipate the moisture through the heat produced by the speaker.

3. Maintenance of the wiper system and drainage system

As a necessary tool for vehicles on rainy days, wipers must be checked in time for the use of each switch and gear during daily maintenance. At the same time, pay attention to checking the wiper blade, and replace it in time when it cannot wipe the glass clean;

Furthermore, pay attention to cleaning the gutter and drainage hole usually located under the lower part of the windshield to prevent rainwater from accumulating in the windshield. The underside of the front windshield causes rainwater to seep into the car. Therefore, it is necessary to clear the drainage holes in time to avoid water accumulation.

IV. Maintenance of the brake system

Because brake oil is easily fused with water, a large amount of moisture vapor accumulated on the brake tank due to the weather during the rainy season can easily enter the system. In fluid. If moisture enters the brake fluid, during the braking process, the high temperature generated by friction will cause the water to vaporize and be compressed in the brake fluid, causing brake failure or even failure. Therefore, after continuous rainy days, attention should be paid to checking the fluid in the brake system and bleeding the brake system.

5. Be sure to prevent water from entering the front air grille

Try to avoid waterlogged roads when driving. If you cannot avoid it, you should also slow down and let the vehicle pass slowly. This will prevent water from pouring back into the air intake system, causing the air filter to get wet and condensing a large amount of mud, resulting in poor air intake and inability to accelerate the engine. In more serious cases, water will directly enter the engine through the air intake duct, resulting in Engine damage.

6. Cleaning of the chassis

In heavy rain, the car should be cleaned in time after driving back, otherwise it may cause sludge to adhere to the inside of the tire and the chassis, which can easily causing rust in these places. Chassis maintenance is generally done by a professional car repair center.

The general steps are to clean first, then perform anti-rust treatment, and do a chassis anti-rust treatment. The anti-rust effect can last for 3 months or even longer. If the original vehicle has not had a chassis seal, it is best to have a chassis seal.
