How to maintain the car in the cold winter has become a topic of great concern to car owners. In consultation with the industry, summed up some winter car, maintenance experience, come to have a look!
Vehicle maintenance in winter: Inspection
1. Check the heating system
The maintenance of warm air is particularly important in winter. If there is any damage, repair it in time, or it will freeze to death in winter.
2. Check the wiper
In winter, the wiper is frozen on the windshield by snow water. Do not wash it directly with hot water. The correct way is to start the car, turn on the air conditioner, and wait for the wiper to turn on naturally. If possible, the anti freezing windshield can be replaced to avoid freezing in winter.
3. Check the light
Make a comprehensive inspection on the lights of the whole car, and replace the blackened bulbs as soon as possible, especially fog lights, brake lights, and turn signals. Visibility is low in foggy weather in winter, and there are not a few rear end collision accidents caused by lighting problems.
Vehicle maintenance in winter
1. Battery maintenance
The battery is most afraid of low temperature. In the low temperature environment, the capacity of the battery is lower than that of the normal temperature. Although the current batteries are maintenance free, before the winter comes, the terminals of the battery should be cleaned and coated with special grease to ensure reliable starting. If the vehicle is not used for a long time, the battery should be removed and stored in a room with higher temperature to prevent battery damage.
2. Glass water
In winter, when using glass water to wash the front windshield, it is necessary to select high-quality glass water, so that the glass will not freeze when washing. Appropriate proportion of alcohol can be added to reduce the freezing point and achieve the purpose of anti freezing.
3. Antifreeze
The antifreeze is required to be used for no more than 2 years. It must be replaced or added in time. At present, the freezing point of Antifreeze on the market includes - 15 ℃, - 25 ℃, - 30 ℃ and - 40 ℃. The lower the freezing point, the stronger the antifreeze resistance. The freezing point of antifreeze solution should be 10 ℃ lower than the minimum temperature in the area. The outdoor temperature is low, only enough antifreeze can ensure the normal operation of the vehicle in cold environment. Otherwise, the water tank will be frozen and the normal circulation will lead to vehicle failure. In winter, we should form the habit of regularly checking the use of antifreeze.
4. Engine oil
The engine oil plays an irreplaceable role in the normal operation of the car. Before using the vehicle everyday, you must carefully check whether the oil dipstick is within the normal range. You can change the oil according to the mileage in the maintenance manual.
5. Tire
In cold winter, try to ensure high tire pressure. The rubber tire will become hard and brittle due to the decrease of temperature, and the friction coefficient will be reduced. The tire with greater wear should be replaced. Four wheel dynamic balance should be performed regularly. It is recommended that the old drivers in Northeast China replace the snow tire.
6. Whole car beauty
Before winter, you should do a whole car beauty, and the number of car washes in low temperature environment will be reduced. Therefore, waxing in early winter is a good way to maintain the car paint. In addition, waxed car bodies are not easy to get water, and the paint surface in winter is not prone to condensation and ice formation.
7. Chassis maintenance
In winter, especially after passing through the road with snow melting agent, it is necessary to clean the vehicle chassis in time, so as to prevent the vehicle chassis from being corroded by snow melting agent. It is better to do anti rust treatment for the chassis before winter.
Vehicle maintenance in winter
1. Eliminate static electricity
In winter, the air is dry and cold, and it is easy to generate static electricity. Many old drivers are electrified when they open the door. Before going out, they can wash their hands or use the metal part of the key to click the lock of the car to avoid this situation.
2. Open the skylight
In cold environment, it is very easy to cause the vehicle skylight to freeze. If it is forced to open, the excessive resistance caused by freezing may burn out the original skylight. Therefore, before using the skylight, turn on the heating inside the car, open the windows on both sides a little, and wait for the temperature to rise before opening the skylight.
3. Hot car
Before driving, warm the car in place or let it move slowly without filling door. In cold environment, the oil consistency increases and the circulation slows down. The hot car can ensure the vehicle oil and antifreeze in place to the greatest extent and reduce the wear of the vehicle.
4. Use the handbrake correctly
After rainy and snowy weather, there will be snow water on the brake disc. The disc may be frozen, causing the hand brake unable to be put down or the brake can not be released after being put down. When parking for a long time in rainy and snowy nights, it is better to park the car on the road surface of the platform, and then put the car in the parking gear to find the support to fix the vehicle. In this way, the brake disc can be prevented from freezing, and the car can also be avoided from sliding.
