How to maintain the car after rainy days

The weather in Beijing this year is cloudy and unpredictable, and the season is a bit abnormal. After entering the rainy season, what maintenance should be paid attention to?

Many people like rainy days and prefer the fresh air after rainy days, but rainy days are more challenging for cars. Because in rainy days, wet weather will cause a lot of water to accumulate on the brake fluid cup and enter the brake fluid. If moisture enters 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 brake failure or even failure. Therefore, it is necessary to maintain the vehicle after a rainy day. Let’s take a look at the way to maintain the car after the rain.

One, wash the vehicle in time after it rains

Acidic substances in rain water can cause damage to the paint. If the car is not cleaned in time, the paint will lose its luster. Do not wait for a few days after the rain to wash the car, wait until it is clear to wash, waxing or sealing glaze can effectively protect the paint surface of the car and prevent the paint surface from fading and aging.

2. Self-check whether the brake fluid is damp

The wet weather in the rainy season will cause a large amount of water to accumulate on the brake fluid cup and enter the brake fluid. If moisture enters 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 brake failure or even failure.

At this time, the car owner can verify whether there is a problem with the brake system through three conditions: the brakes need to be stepped deeply, the brakes are audible, and the braking distance is longer than before. If one of these three conditions occurs, the vehicle will stop. Go to the repair shop for inspection.

3. Check the circuit of the vehicle after the rain

When it rains on some cars, the engine is not easy to start. Even if you barely start, you always feel that the engine is “powerful”. This is because the car’s electric circuit or ignition system is damp.

When the car is wading in water, check it in time. If it is found that the ignition system is too humid and the ignition is poor and the engine performance is degraded, dry the electrical equipment with non-fiber paper towels or textiles, and then try to start.

If the engine stalls due to moisture, do not re-ignite and start repeatedly to avoid damage to the engine.

4. Pay attention to dehumidification inside the car after rain

On rainy days and the air is humid, riders should pay attention to the anti-bacterial inside the car, especially the hygienic corners such as car seat cushions, textile carpets, and air outlets. It is recommended that car owners who like car perfumes use neutral, light-smelling perfumes in summer, and do not use acidic perfumes such as lemon. When it rains, you can turn on the cold air of the air conditioner, which not only removes the fog, but also has the function of removing moisture. Putting a roll of old newspaper in the car can also effectively remove the moisture in the car.

5. Chassis encapsulation is beneficial

After heavy rain, the car chassis should be cleaned in time; if there is sludge accumulated in the chassis part, it is easy to hide moisture in it and cause the chassis to rust.

The chassis encapsulation can isolate the chassis from the air, achieving the functions of anti-corrosion, anti-rust and sound insulation. The chassis encapsulation is generally done by professional car maintenance personnel, and the whole process takes 30-40 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, a special detergent should be used to remove the asphalt and oil attached to the chassis, and the heat dissipation parts of the transmission and exhaust system should be blocked, so as to achieve a good protective effect.

Six, the headlights have a big risk of fog

When it rains, the headlights of the vehicle are prone to water, the brightness is affected, and the illumination direction of the headlights changes, which may damage the headlights and bring safety hazards.

If there is water mist in the headlights, you can turn on the headlights. Whether the water mist in the car lights starts to disappear after 10 minutes of driving, and whether it can completely disappear after one hour; if there is still water mist, you must go to a professional after-sales service station for treatment.

Seven, check the engine in time after the vehicle enters water

If the vehicle is flooded with water, remove the battery’s negative wire as soon as possible to avoid short-circuiting of various electrical appliances on the vehicle due to the water entering. After the car comes out of the water, check the engine: first check whether there is water in the engine cylinder, which will cause the connecting rod to be bent and damage the engine.

8. Check if the engine oil has entered water

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

Nine, check whether the battery has water

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

10. Don’t forget to check the trip computer

Automatic transmission vehicles should check whether the automatic transmission and the transmission control computer are flooded.

Summary: If it is a little bit of light rain, you don’t have to worry about the problem with the vehicle. But if there is continuous rain, or after heavy rain, and the vehicle has been wading, you must carefully check whether there is a problem with the vehicle and prepare for maintenance.
