The weather in Beijing this year is uncertain and the season is a bit unusual. After entering the rainy season, what maintenance should the vehicles pay attention to?

Many people like to rain, prefer fresh air after the rain, but rain is more testable for cars. Because on a rainy day, wet weather will produce a lot of water on the brake fluid cup and enter the brake fluid. If there is moisture entering the brake fluid, the high temperature generated during the braking process of the vehicle will evaporate a large amount of water vapor, and the compressibility of the gas will cause the brake to malfunction or even fail. Therefore, it is necessary to maintain the vehicle after the rainy weather. Let's take a look at the method of car maintenance after the rainy weather.

First, it is necessary to clean the vehicle in time after rain

Acidic substances in the rain can cause damage to the paint. The car is not washed in time, and the paint can easily lose its luster. Do not wait until a few days after the rain to wash the car, to wait until the sky is clear, to wash, waxing or sealing glaze can effectively protect the car's paint to prevent paint fade aging.

Second, self-test brake fluid is damp

The wet weather during the rainy season will generate a large amount of water on the brake fluid cup and enter the brake fluid. If there is moisture entering the brake fluid, the high temperature generated during the braking process of the vehicle will evaporate a large amount of water vapor. The compressibility of the gas will cause the brake to malfunction or even fail.

At this time, the owner can confirm whether the brake system has problems through three situations: the brakes need to step deeply, the brakes are heard, the brake distance is longer than before, and one of these three situations occurs. Have to check in the repair shop.

Third, check the vehicle circuit after rain

When some vehicles arrive on a rainy day, the engine is not easy to start. Even if it is barely started, it always feels that the engine has "power". This is because the car's circuit or ignition system is damp.

When the car is wading, it is necessary to check it in time. Once it is discovered that the ignition system is too humid and the ignition is poor and the engine performance is deteriorating, it is necessary to use non-fibrous paper towels or textiles to dry the electrical equipment and try again.

If the engine stalls due to moisture, do not repeatedly start the ignition so as not to damage the engine.

Fourth, notice the dehumidification in the car after the rain

On rainy days, with damp air, riders should pay attention to the interior of the car against bacteria, especially car seats, textile carpets, outlets and other health corners. It is recommended that owners who like car perfumes use neutral, light-tasting perfumes in the summer and do not use lemony and other acidic perfumes. When it rains, you can turn on the cold air of the air conditioner. This not only removes fog, but also removes moisture. Placing an old newspaper in the car can also effectively remove the moisture in the car.

Fifth, chassis molding has benefits

After heavy rain, the chassis of the vehicle should be cleaned in time; if there is sludge accumulation in the chassis, it is easy for moisture to hide and cause the chassis to rust.

Chassis sealing enables the chassis to be insulated from the air, achieving anti-corrosion, rust-proof and sound-insulating functions. Chassis molding is generally done by professional car maintenance personnel. The entire process takes 30 to 40 minutes. After the chassis is sealed, the effect can be maintained for 3 months or even longer. It should be noted that before the chassis is sealed, special detergents should be used to remove the asphalt and oil adhered on the chassis and cover the heat-dissipating parts of the transmission and exhaust system so that good protection effects can be achieved.

Sixth, the headlamps have a big hidden danger

When it is raining, the headlights of the vehicles are prone to flooding, the brightness is affected, the direction of illumination of the lights changes, and the headlights may also be damaged, causing potential safety hazards.

If the headlights have water mist, you can turn on the headlights. After 10 minutes, if the water mist in the headlights starts to disappear, can it completely disappear after one hour; if there is water fog, it must go to a professional after-sales service station for processing.

Seven, check the engine in time after entering the water

If the vehicle enters into the water, it is necessary to remove the negative wire of the battery as soon as possible, so as to avoid short circuit due to the inflow of various electrical appliances on the vehicle. After the car comes out of the water, it is necessary to check the engine: first check whether the engine cylinder has water, and the water will cause the connecting rod to be bent and damage the engine.

Eight, check whether the oil into the water

Once the oil enters the water, it will cause the engine oil to deteriorate, lose its lubrication effect, and cause excessive engine wear.

Nine, check whether the battery water

Check if the battery is full of water and replace the battery if necessary.

Ten, driving computer do not forget to check

The automatic transmission car should check whether the automatic transmission and the transmission control computer enter the water.

Summary: If it is a little bit of rain, you don't have to worry about what's wrong with the vehicle. However, if there is continuous rain or heavy rain, and the vehicle has wading experience, it is necessary to carefully check whether the vehicle is in trouble and prepare for maintenance.
