How Do You Take Care Of Your Car After It Rains

BY Nathan Tillman Update: January 5, 2022

When you put your car outdoors, the two things you fear most are exposure to the sunlight and rainstorms.

After a rainstorm, many automobile owners feel that their car driving differs somewhat from usual.

After heavy rain, many car owners are worried about whether the car will have an accident because, after the rainstorm, there is no problem with the car. In fact, the real problem will not appear directly in front of you. Let you know you need to check and maintain your car to solve the potential hidden dangers of the car.

But it is more important to know what happens to the car after it rains and how to maintain your car.

Problems That Cars Will Encounter In Rainstorm Weather

1、 The most important thing in the rainy season is the maintenance of car engines. Car owners will encounter the problem that the engine is difficult to start on rainy days. The biggest reason is the leakage caused by humidity in the ignition system. Once it is found that the humidity of the ignition system causes the poor ignition and engine, you can temporarily wipe the inside and outside of the distributor and the wires with dry cloth. If it is due to aging and leakage, you must replace it in time.

2、 After wading, performing the vehicle decreases due to water inflow in many places, which may lead to the vehicle not running normally. This is most likely because of the leakage of electricity from the ignition system due to humidity.

Because muddy rain is the best conductor, the circuit is likely to cause a short circuit when it meets water. If the engine suddenly stalls during driving, do not start the ignition repeatedly. You should wait a while or get off the car to check the circuit, otherwise, it is very easy to cause the engine to be scrapped.

3、 When the road is slippery on rainy days, the possibility of side slip increases. The vast majority of car braking systems are double pipe vacuum-assisted hydraulic braking.

4、 For some vehicles with serious water absorption of brake fluid, we can see water droplets on the brake fluid cup cover. Therefore, the brake fluid must be checked during maintenance to ensure the life safety of drivers and passengers.

Once it is found that the vehicle brake fluid absorbs water seriously, they should send it to a professional maintenance shop for water removal.

5、 Before the rainy season, if we find that we have seriously worn the vehicle tires and the tire tread disappears, we must replace them. Some people reduce the tire pressure every rainy season to increase the friction area between the tire and the ground and then increase the adhesion. In fact, it is counterproductive, which is more likely to cause tire slip. It is very important to maintain normal tire pressure.

6、 Wiper failure: if you often drive in heavy rain, nuclear vision must be the biggest hidden danger, and the importance of wiper will appear. The increase of rain in the rainy season will inevitably make the wipe bear more responsibilities, and the inspection and maintenance of the wiper should be more careful. Because the road surface and line of sight on rainy days are not conducive to driving, if the wipe can not brush off the rain well, it will bring great danger to driving safety. The owner can place the wiper switch at various speed positions, pay attention to whether there is vibration and abnormal noise during the operation of a wiper, check whether the wipe at different speeds maintains a certain speed, and observe the scraping state and whether the wipe support rod swings unevenly or misses scraping. Either of these two faults means that the wiper blade is damaged.Vehicle Maintenance After A Rainstorm.

Car Maintenance After A Rainstorm

Clean the body

Heavy rain not only brings mud to the car body but also viscous substances such as asphalt. Over time, it is easy to firmly adhere to the car shell and difficult to remove. The damage to the paint after rain is actually the greatest.

The reason is that the rain is very dirty, not only mixed with dust in the air but also contains many acidic and harmful substances. If we attach these substances to the car paint for a long time, it will have a great impact on the service life of the paint. Therefore, it is best to wash the car as soon as possible after the rain to keep the paint surface clean.

Check the brake system

When it rains, the brake disc will inevitably come into contact with water, so after a rainy day, you find that the brake disc is full of rust. The brake disc itself is cast iron, and rust is normal.

Because the brake oil is easy to integrate with the water, in the rainy season, because of the wet weather, the large accumulation of water vapor in the brake tank is easy to enter the brake fluid. If water enters the brake fluid, the high temperature generated by friction will vaporize the water during baking.

If you find that the brake disc is rusty, please don’t worry. You drive out and step on the brake with moderate force on the road. After repeated steps, the rust on the brake disc will be eliminated, so that your driving will be safer.

Interior dehumidification

When it rains, turn on the cold air, which can not only remove the fog but also dehumidify. On a Rainstorm Day, you can imagine how wet the interior of the car is. When the sun comes out after the rain, take out the foot mats and seat covers that can be removed to dry and remove the moisture.

Besides the rust and corrosion of the door welding and body welding parts after the rain, the iron parts such as hinges and latches inside the door are also vulnerable to moisture because the door trim panel covers them.

Therefore, when the weather is sunny after the rain, open all doors and rear compartment covers to exhaust and ventilate the moisture in the car, and then remove the footpads and seat covers in the car, wash and dry them.

Car paint needs maintenance

Vehicles parked outside must maintain the car paint in time after the rainstorm because the rain contains acidic components, which have a strong corrosive effect on the paint and can be waxed.

Check the car sunroof

The skylight is the weak link of the car and will become a place for rainwater and dirt. During maintenance after rain, first, clean the sediment or leaves adhered to the sunroof sealing strip, and check whether the sealing strip is deformed or notched, to prevent excessive rainwater from penetrating into the sunroof and causing water leakage in the vehicle. Second, lubricate the sunroof guide rail.

Automobile chassis maintenance

The chassis is the part closest to the ground, which is particularly seriously affected by road conditions. This part is most prone to rust spots, and the wheel cavity may even be loose and perforated. Therefore, we must pay attention to the cleaning and antirust treatment of the automobile chassis. In case of heavy rain, we can clean the car after driving home. First, wash away some acidic substances. Second, after driving on rainy days, there will be sludge residue on the inner side of the tire and chassis, and the moisture will hide in it, which can easily lead to rust in these places.

Check the circuit

Even the most important part of the automobile, the circuit of the automobile, is also a very weak link in the automobile. Therefore, for your car to operate normally, you must check the circuit in time after the rain.

The key is to check the high-voltage line. If there is wading, the circuit equipment shall be treated in time after that, and we can wipe the circuit dry with non-fiber paper towels and textiles.

Check the brake system

Because the braking system has a very strong adsorption force, rainwater is very easy to enter the brake fluid, which will affect the braking effect and seriously cause braking failure.

Check the lights

After heavy rain or wading in the water, if the quality of the lamp is not very good, it is easy to enter the water.

After the lamp enters the water, not only the brightness will be affected but also the lamp circuit may be damaged, and it will change also the irradiation direction of the lamp, which will bring hidden dangers to driving safety.

Therefore, it is important to check whether we flood the lamp after rain. The headlights of vehicles parked outside are easy to get water, especially on rainstorm days.

There is a lot of water in the rainy season. You can turn on the headlights to dissipate heat and remove water mist. If it is still invalid, send it to the maintenance factory for maintenance in time.
