Soon we will have to say goodbye to the fall, and we will enter the cold winter for car owners. In the cold winter, the car has become a warm haven for us when we go out. However, in the cold weather, wind and snow, how to make the car can safely overwinter, to avoid adverse effects of low temperature on the car, we also summed up some experience and precautions for everyone to make a reference.
1. Inspection and replacement of engine oil Also known as lubricating oil, it is one of the most important items in automobiles. Any car needs to use lubricating oil, it can play a good role in engine lubrication, cooling, etc., can better protect the engine to make it run more smoothly and use longer. Then below, we will talk about what we should pay attention to when using motor oil in winter.
At present, the engine oil on the market uses SAE and other grades of labeling viscosity. SAE is the abbreviation of the English Association of Automotive Engineers. For example: SAE15W-40, where "W" means winter (Winter), the smaller the number in front of "W", the more dilute the oil, the better the cold flowability, the better the cold start capability, can be used in a lower temperature environment .
When conducting inspections or maintenance, individuals can properly replace the applicable minimum oil temperature in their own area and can avoid the difficulties caused by the low winter temperatures and the purpose of engine maintenance.
2. Check the antifreeze and glass water glass are also divided into summer and winter use. Remember to change to winter glass water before entering the winter season. Although it can be replaced by fresh water and clear water in the summer, these alternatives may freeze in the winter and cannot be used during the winter. In the winter environment below 0°C, frost-resistant winter glass water should be replaced. Or in the glass water by adding an appropriate proportion of alcohol can also achieve the purpose of reducing the freezing point, antifreeze.
Some owners like to use ordinary tap water as the role of glass water in the summer. There is no harm in doing so. Tap water contains a lot of impurities, a long time, impurities will adhere to the rubber tube, affecting the normal water spray. Long-term use may increase the friction between the glass surface and the wiper, causing scratches on the glass. In fact, the clean water can only be used to clean the dust. The dirt and corpses that adhere to the windows cannot be cleaned thoroughly. In the winter, you must not forget to replace the antifreeze glass water and replace the glass water for the temperature in your area.
In the cold winter, be sure to use special antifreeze for the car in winter. In particular, the weather in the north is cold and most of the time the temperature is below zero. If the engine's cooling system is ordinary water, it will form ice, and if it is light, it will cause the car to fail to start normally, and it will cause serious engine damage.
3. Checking the electrode connection of the car battery The battery is a place where problems occur during the seasons, so pay attention to maintenance. During the inspection, if there is a green oxide at the electrode connection, remember to flush it with boiling water. If these green oxides are not removed, it will cause the generator to run out of power, causing the battery to be in a deficient state, which can cause serious damage. The early retirement of the battery, or can not beat the car. After flushing with boiling water, dry the water with compressed air and spray with a special protective agent to prevent the oxide layer from reappearing.
4. Check the high temperature of the tires in spring and summer. In order to prevent tire inflation with high tire pressure, the tire pressure should be checked frequently. When the temperature falls in autumn and winter, air pressure should be added to keep it within the specified air pressure range. At the same time, check the tires for scratches, because rubber tends to harden in the fall and winter seasons, and tires can easily leak or puncture tires. Tire pressure can be as long as it meets its own specifications.
5. Check the air filter Usually the three filters we have heard of, in fact, they are the name of the gasoline filter, oil filter and air filter, and the air filter we usually call the air filter, we all know The operation of the engine requires a large amount of air and gasoline combined combustion, dirty filter can not achieve good filtration, it will make the engine load more, over time, will have adverse consequences on the engine and great damage to life.
6. Checking the lights and lights of the vehicle is mainly to check if the headlights, fog lights, brake lights and turn signals are working properly. If one or more items are found to be a problem, it may be that the lamp has reached its end of life, or it may be a circuit failure. It is recommended to carry out systematic inspections. Rain, snow, and fog often appear in winter. Normal lighting or not is directly related to our driving safety.
7. The brake system check brake pads are also called brake pads. In the brake system of a car, the brake pads are the most critical safety parts. All brakes are good or bad brake discs play a decisive role. Therefore, a good brake pad is a protection person for people and cars.
Other notes:
1. The air-conditioning system detects that winter has reached the season of using warm air. After the heater system is deactivated for a long time, it will also malfunction. Therefore, first try whether there is hot air, whether the fan runs abnormally, and whether the air duct is unobstructed. . Sometimes the antifreeze in the warm water pipe does not flow for a long time, and the condensation clogs the circulation pipe. Although it does not affect the traffic, it is very troublesome to repair, and the problem must be promptly repaired by the repair shop.
2. Make a "beauty"
It is best to do a "beauty" for the body of the car before winter. Because the number of days after freezing in the cold and brushing vehicles will decrease, winter waxing is a good way to maintain the paint. In addition, the waxed body is not easy to wet, and it is not prone to condensation and ice formation in winter.
3. The belt inspection The inspection of the belt is also not negligible. If there is a phenomenon of slipping or breaking, the related auxiliary engine will lose its function or its performance will be degraded, thus affecting the normal use of the vehicle. There is also an aging problem with the belt's rubber. If the belt rubber is seriously aged, it must be replaced with a new one in time.
Summary: The winter season is coming soon, and the winter maintenance of the car is crucial. Some car owners think that it is not necessary. In fact, it is a time when they are in danger. It is because they have not carried out the necessary inspection and maintenance of the vehicle. In particular, in the winter in the north, temperatures are basically below zero, and the use of vehicles is also multiplied. Therefore, it is important to prepare for a thorough inspection of the vehicle before entering the winter to make travel safer.
