Small knowledge of automobile maintenance in rainy days

Driving in rainy days is likely to cause many safety hazards, not only because the road surface is slippery, but also because rain will cause certain damage to vehicles. Therefore, it is necessary to clean and check the car in time after the rain and maintain the car.

The first step is to clean the car body in time. Acidic substances in rainwater will damage the paint of vehicles. If it is not cleaned in time, the paint will become dim or even fade. Therefore, as soon as there is sunshine, the car body should be cleaned, waxed or glazed to protect the paint surface and prevent aging and fading.

In addition, the wet weather in rainy season will also affect the braking system of vehicles. Rain will enter the brake fluid, causing the brake fluid to get wet. However, the high temperature generated during braking will make water evaporate into gas, which will lead to brake failure or even failure.

So check whether there is a problem with the brake system. If it is found that the brakes need to be pressed deeply, there is abnormal noise when braking or the braking distance is longer than before, these are all manifestations of possible problems in the braking system, and the vehicle should be sent to the 4S shop for inspection and maintenance as soon as possible.

To sum up, rainy days not only bring inconvenience to riders, but also may cause damage to vehicles. Therefore, it is necessary to clean the car body and maintain the paint surface in time after the rain; At the same time, check whether there is any problem with the brake system to ensure driving safety. These are all indispensable links in the daily maintenance of vehicles.

The circuit must be checked after the rain.

Check the vehicle in time after wading. If it is found that the ignition system is too wet, resulting in poor ignition and engine performance degradation, it is necessary to dry the electrical equipment with non-fiber paper towels or textiles, and then try to start it. If the engine is shut down due to humidity, do not ignite it repeatedly to avoid damaging the engine.

Dehumidification in the car is indispensable.

Car owners who like car perfume should use neutral perfume in summer instead of acidic perfume such as lemon. You can turn on the air conditioner in rainy days, which can not only demist but also dehumidify. Putting an old newspaper in the car can also effectively remove the moisture inside the car.

Chassis sealing is beneficial.

Plastic packaging of the chassis can isolate the chassis from the air, and achieve the functions of corrosion prevention, rust prevention and sound insulation.

Before the chassis is sealed, special cleaning agent should be used to remove the asphalt and oil stains attached to the chassis, and cover the heat dissipation parts of the transmission and exhaust system for good protection.

The headlights are foggy and need to be removed.

In rainy days, car headlights is easy to get water, and the brightness is affected. The headlight irradiation direction changes, and the headlight may be damaged, which brings security risks. If the headlights are foggy, you can turn on the headlights. After one hour, if there is still water mist, it will be handled at the professional 4S shop after-sales service station.

Engine timely inspection

First of all, the negative wire of the battery should be removed as soon as possible, so as to avoid short circuit of various electrical appliances in the car caused by water ingress. Check the engine after the car comes out of the water, and check whether the engine cylinder is flooded, which will cause the connecting rod to bend and damage the engine.
