In the cold winter, not only do we need to keep warm, but the car is also very “cold”, especially in the case of sudden low temperature, many parts of the car are more fragile than usual, and can not be too violent. Like people, is your car ready for the winter? The season change has a very big impact on the vehicle. Therefore, in the winter, the maintenance work of the car is very important. The following small series should tell everyone about the practical and practical tips for winter car maintenance.
01 Check battery power
Winter is a high season for battery failures. The lack of electricity in the battery is the most common problem in this season, so it is important to check the battery level. First check the battery’s large wire connector for looseness and corrosion. If it is loose, tighten it with a wrench. If you find white oxide at the electrode connection, you can wash it off with warm water, because these oxides will cause the resistance to become larger, causing the generator to run out of power, causing the battery to be in a deficient state. In severe cases, it will cause the car to be lost or The battery is scrapped.
Normally, the life of a car battery is 3 to 4 years. If your battery has exceeded this time, especially into the winter, don’t hesitate to change it. Because the battery will vary greatly according to the ambient temperature, the lower the temperature, the lower the storage capacity.
02 Pay attention to the brake Check the brake
Winter roads tend to freeze, and car braking is an important part of life. Whether the brake fluid is sufficient, the quality is changed, the brake is weakened, the deviation is reversed, the pedaling force of the brake pedal and the position of the wheel lock point during braking are required to be checked in winter. In fact, the maintenance of the brake system requires us to pay more attention during the usual driving process. In the event of an abnormal change, immediately go to the repair shop for maintenance, and if necessary, clean the entire brake system piping.
03 Protective chassis Pay attention to rust prevention
The maintenance of the chassis, first of all, is to thoroughly clean the chassis to keep the chassis in its original state. In the second step, we need to rust the chassis. The most effective method is to install the chassis armor. Special elastic rubber material is sprayed on the surface of the chassis to prevent rust, abrasion, shock absorption and noise reduction, which can provide good protection.
04 Cleaning the glass Checking the wiper
When the weather is cold, the temperature is low, and it is raining or snowing, the wiper on the windshield is easily frozen. If the wiper is started hard, it is very likely that the wiper motor has been broken; do not flush it directly with hot water, which will easily cause the window to burst due to temperature changes and the wiper to deform. The correct way to check whether the wiper is frozen before using the car in winter, if it is found that the wiper sticks to the front windshield, the engine should be started first, the air conditioner hot air is turned on, and the wiper is naturally thawed. There is also a simple antifreeze method, which is to erect the wiper when parking at night. In addition, although the amount of glass cleaner used in winter will be significantly less than other seasons, the role can not be ignored. It should be noted that the cleaning agent should be replaced with an anti-freeze type in time, and it will not freeze under °C or even below 30 °C.
05 Check the light to ensure a clear view
In many places, accidents occurred in winter cars due to fog, frost, and blizzard. At this time, the visibility was low when driving, and there were many rear-end accidents. Therefore, whether the fog lamp or the high brake light works normally is directly related to the driving safety in winter. The lighting inspection mainly includes fog lights, headlights, high-position brake lights, etc. Once the blackened light bulb is found, it should be replaced as soon as possible.
06 Adjustment of the lubrication system
In the summer season, due to the high temperature, the oil fluidity is good, and the engine uses a large viscosity oil to ensure the proper consistency to achieve the lubrication effect. Entering the winter weather, temperatures below zero will cause the cold motor oil to be too thick, which will affect the start-up and increase the wear of the parts. Therefore, in winter, the oil in the oil pan and air compressor should be replaced with the oil for winter; the gear oil in the transmission, transfer case, differential and steering gear should be replaced with gear oil for winter. After cleaning the hub bearing, add a lower viscosity bearing lubricant. The lubrication of the car is required in winter, and it must be replaced if it is used in summer.
07 winter car wash
Wash the car in winter, do not rinse directly with cool water as in spring, summer and autumn, but wash the car with warm water. At the same time, the engine cannot be flushed directly with water. Because the temperature of the front part of the car is high after the engine is warmed up, it is easy to cause rapid cooling when it is directly washed with normal temperature water, which may damage the paint of the car; and it may damage the components outside the engine, such as the battery. It should also be noted that after washing the car, the door, window and dry air should be opened to prevent freezing. So troublesome, there are many car owners who simply don’t wash the car. This is very undesirable, because the car wash in winter is not only to keep the paint paint shiny, but more importantly, to wash off the salt or snow melting agent attached to the car body after snow. The long-term adhesion of salt or snow melting agent will corrode the car body and shorten the car. The paint has a normal service life.
08 Use of air conditioning
The temperature in winter is low, and many people will turn on the warm air when they get on the bus. This is normal. However, in the afternoon or at night, it is easy to get into trouble. I hope that you will not let the warm air go too far. The warmth inside the car will make people more sleepy, thus increasing the safety hazard of driving. The warm air is open to the right temperature, not cold. In addition, some drivers use only the inner circulation of the air conditioner when driving in winter, because the biggest advantage of the air circulation mode is to increase the temperature inside the vehicle for a short time, which can make the car have a warm and comfortable environment. However, the shortcoming of the air conditioning internal circulation is that the frequent use of the second-hand air in the car will greatly reduce the air quality and damage human health. Therefore, it is recommended that the owner alternately use the inner/outer cycle to increase the temperature inside the car on the basis of ensuring fresh air.
09 go out moderate warm-up
Most car owners think that the longer the hot car is, the better it is, the easier it is to start. It is good for the car engine and other hardware. In fact, after the hot car takes too long, it will not only consume a lot of gasoline, but also damage it. engine. The correct way to drive the car should be to start the vehicle, the original hot car for 20-30 seconds, then start the slow driving, do not step on the throttle at the beginning, keep the engine speed at around 2000, and then accelerate after the temperature returns to normal temperature. .
10 tire pressure monitoring
Some car owners like to charge the tires at a high pressure, which is considered to be both overloaded and fuel efficient. But in fact, this is not desirable. Excessive tire pressure will reduce the contact surface between the tire and the ground, and the tread wear will increase, reducing the braking effect during braking. Of course, the tire pressure is too low is not good, in addition to affecting the driving safety and braking effect, it will also accelerate the wear of the shoulder and increase the fuel consumption of the vehicle. Adjust the tire pressure appropriately, and also regularly check whether the sidewall is cracked, damaged, or bulged. If you have a similar situation, you must go to a professional auto repair shop or 4S shop immediately.
11 Antifreeze replacement
In the cold winter, it is a necessary event to replace the antifreeze. If you find that the antifreeze in the car is obviously insufficient, do not add fresh water directly. This will reduce the freezing point of the antifreeze and affect the use effect. In addition, different brands of antifreeze should not be mixed, because the various types of antifreeze are different in the proportion and composition of the preparation, the freezing point is different, you need to choose according to the temperature conditions. If the color of the antifreeze is dark and turbid, the quality is degraded. After the freezing point test, replace the antifreeze in a timely manner. If you want to replace another brand of antifreeze, first remove the residual antifreeze from the car.
Regardless of the season, car maintenance has some different skills, especially in winter rain and snow. If you don’t care for yourself, then it’s too late to wait until the car goes wrong. It is still the most important safety of the road!
