Some misunderstandings in winter car windows are not watered with boiling water

【The owner's family car knowledge】Frequent visits in rainy and snowy weather make how to maintain a car in snowy weather has become a problem that car owners must face at present. Some car owners think that hot water is used to pour the ice on the windows to de-icing the fastest; some car owners think that snow chains can be installed on any wheel; some car owners don’t care about the car after it snows, and let it go... As a result, these are not. Appropriate handling methods have caused minor or severe damage to the car. Let's take a look at the mistakes of these car owners.

Misunderstanding 1: The car windows are frozen and take away the water

The owner, Ms. Xu, "knows nothing" about car maintenance and admitted that she is a "rookie" in this respect. No, she did something stupid this time when it snowed heavily. It snowed all night and got up in the morning. Ms. Xu found that her car was covered with ice and snow that was difficult to remove. She was impatient and brought a bucket of hot water for granted, thinking that taking a hot bath for her car would drive away the cold. , But at some point, the windshield of the car suddenly burst.

Tips:Master Zhang from a car beauty and decoration shop told reporters that if you want to de-icer, you can start the engine first, turn on the warm air in the car, and use a special snow shovel for car glass to slowly remove ice from the cracks in the ice. If you take a hot shower after the snow, it will be devastating to your car, because sudden changes in temperature will damage the paint and make it gradually lose its luster, and the windshield of the car may also be pouring hot water. Burst in. Washing the car after snow can not be washed directly with cold water, especially after the engine heats up, the temperature of the front of the car is higher, washing with cold water will cause rapid cooling, which is very unfavorable to the surface paint. The correct way to wash the car at this time is to start the car and turn on the heating system on the car, and then wipe the car with warm water. After rinsing, the door should be opened to wipe off the water stains to prevent the residual water at the door cracks from freezing. Do not forcefully open or close the window when it is frozen, especially the power window.

solutions:The reason why the glass freezes is that after a person leaves the car, there is still hot air inside the car, making the temperature of the car glass higher than the outside of the car. Snow melts first when falling on the glass. During the melting process, the temperature inside the car gradually decreases to At the same time as outside the car, the melted snow on the glass began to freeze; the snowflakes that fell on after freezing would no longer melt, and were covered on the ice like a quilt. In the morning, the snow on the glass is easy to handle. Just sweep it with a broom. The most worrying thing is the layer of ice below. Through observation and analysis, in a snowy day, you can try not to lock the car and leave immediately after using up the car in a day, but to open the doors on both sides for ventilation, and wait for the temperature inside the car to drop to the same level as the outside of the car. Turn on the power and use the wiper to clean the remaining snow on the windshield, then close the door and lock the car. The next morning, as long as the snow on the windshield is swept away, there is no ice under the snow, and you can drive on the road immediately.

Misunderstanding 2: Do not wash the car in time after snow

In rainy and snowy weather, the owner of the car, Mr. Li, is always used to wait until the weather is completely clear before washing the car. Wash it again.” So in bad weather for several days, the car wash will be delayed again and again. However, Mr. Li regretted the result of doing this: After washing the car, he found that the paint was not as shiny as before. NS.

For this, Master Zhang said that the car must be washed in time after the snow, even if the weather forecast shows that it will snow in the next few days, do not drag the car without washing it. As long as it is covered by snow, immediately wash away the snow with clear water. Snow contains corrosive components, whether it is paint, chassis, tires or wheels, long-term coverage of snow will cause damage. In addition, when washing the vehicle in the open air, it is easy to pour clean water into the keyhole. At this time, it is particularly easy to freeze the lock cylinder due to the cold weather after snow. Therefore, before washing the car, it is best to stick the keyhole with tape to prevent water from entering. Use the car washing machine to wash the car, the water mist is even, and the chance of the door being frozen is relatively small. If it freezes, burn the key with a lighter to easily unlock the frozen car lock.

solutions:If it is predicted that it will snow at night and you have to park the vehicle outdoors, you can prepare newspapers or plastic film to cover the body, or even prepare a car suit in advance.

In this way, as long as the newspaper is lightly exposed the next day, all the ice and snow will be shaken off, and there will be no traces of ice and snow on the vehicle, so there is no need to wash the car frequently.

Misunderstanding 3: Tighten the handbrake at night on rainy and snowy days

Because the snow made the road icy, when Mr. Guo parked the car in his home complex at night, he specially tightened the handbrake to prevent the car from slipping. However, when he drove the next day, he found that the car was not as light as before. , The throttle response is not as sensitive as before, and the speed increase has become a little slow, and the vehicle speed can only be maintained at 80-100 kilometers per hour. If it exceeds 100 kilometers per hour, the car will start to tremble. When he drove the vehicle to the service station for inspection, he found that the handbrake was frozen.

solutions:After rain and snow, there will be snow on the brake discs. If you pull the handbrake at night, the disc may freeze on the next morning. If the car owner parks for a long time on a rainy or snowy night, it is best to park the car on a flat road, hang the car in a gear, and look for a support to fix the car, so as to avoid freezing the brake discs as much as possible.

Misunderstanding 4: Snow chains can be installed casually

"It's snowing. The road is slippery because of the snow. I think other people's cars are equipped with snow chains. I want to ask what are the requirements for buying snow chains." The owner of the car, Mr. Li, called the reporter a few days ago, hoping to do so. Learn what to pay attention to when using snow chains.

solutions:Master Zhang from the car beauty and decoration shop said that you must first confirm whether your car is front-wheel drive or rear-wheel drive, because the chain must be installed on the set of tires that plays the main role. Especially for automatic transmission vehicles, you should pay attention to installing snow chains on the two front wheels (rear wheels) at the same time. Do not use snow chains on only one wheel, which can easily damage the automatic transmission. In addition, snow chains also have size restrictions, which are suitable for different wheel sizes and tire widths. Pay attention to choosing snow chains that match the wheel size. After the snow chains are installed, the driving speed should generally not exceed 50 kilometers per hour. When driving, avoid sudden braking, rapid forwarding, sharp turns and continuous idling. When driving on non-icy and snowy roads, avoid walking on materials with sharp edges and dry roads that are not easy to drive. When the vehicle is driven on a road that does not need to use snow chains, it should be removed in time.

Misunderstanding 5: The wiper freezes and starts hard

"After this snow, the temperature was really low. My car was parked in an open-air parking space. When it started in the morning, I found ice on the windows of the car. After a simple wipe, I turned on the wipers." Mr. Zhou turned on the wiper and started hard. Unexpectedly, the wiper was frozen and stuck to the window glass, and the wiper motor was damaged when the wiper was turned on forcibly.

solutions:Before using the wiper in cold weather in winter, check whether the wiper blade has frozen on the window. If you go out in the morning and find that the wiper is covered with snow or frost on the windshield, do not wash it directly with hot water. This will easily cause the window to burst due to temperature changes and the wiper will be deformed. The correct way is to turn on the air conditioner to hot air, rotate the blowing mode to the "windshield" block, and the wiper will be turned on naturally after a while. It is simple and labor-saving, and will not cause physical damage to the wiper blade. In addition, parking the wiper for a long time when it is snowing can prevent the wiper from freezing.
