A guide to car maintenance before the rainy season

Point 1: Maintenance of wiper systems and drainage systems

As a necessary tool for vehicles in rainy days, in the usual maintenance, we must check the use of each switch and gear in time, and pay attention to checking the wiper piece, when it is not clean glass, it should be replaced in time; then, it is necessary to pay attention to cleaning the flow tank and drainage hole in the lower part of the lower part of the front windshield of the wiper, to prevent rainwater from accumulating under the front windshield and causing rainwater to seep into the car. Therefore, it is necessary to dredge the drainage hole in time to avoid causing water accumulation.

Second, the maintenance of the brake system

Because the brake oil is easily integrated with water, it is easy to enter the brake fluid during the rainy season due to the large accumulation of water vapor on the brake tank due to the weather. If there is moisture entering the brake fluid, during the braking process, the high temperature generated by friction vaporizes the water and is compressed in the brake fluid, resulting in brake failure or even failure. Therefore, after continuous rainy days, pay attention to the oil inspection of the brake system and the deflation treatment of the brake system.

Point 3: Maintenance of paint surface

The acidic components in the rainwater have a corrosive effect on the paint surface of the car, and over time it will cause damage to the paint surface of the car. Therefore, before the summer rainy season, Rui hao can give the car a paint beauty and do a good job of paint protection. For example, waxing or glazing a car can be done according to the actual situation of the car. It is recommended that the new car do a glaze sealing, a good sealing glaze can not only prevent the paint surface from aging, but also the rain will not be water in the car area.

Point 4: Chassis cleaning

In the event of heavy rain, the car should be cleaned in time after driving back, otherwise it may cause sludge adhesion on the inside of the tire and the chassis, which can easily lead to rust in these places. Chassis maintenance is generally done by a professional car repair center. The general step is to clean first, then carry out anti-rust treatment, do a chassis anti-rust treatment, and the anti-rust effect can be maintained for 3 months or more. If the original car has not done chassis sealing, the vehicle is good to do a chassis sealing.

Point five, we must advance the air grid into the water

When driving, try to avoid the waterlogged road, when it is impossible to avoid, you should also slow down and let the vehicle drive slowly, so as not to cause the water to pour into the intake system, so that the air filter is wet and condenses a large amount of mud, resulting in poor intake, weak engine acceleration, and more serious will cause water to splash directly through the intake tract into the engine interior, resulting in engine damage.
