You can travel with confidence in winter.

In the cold winter, the car becomes a warm haven when we go out. However, in low temperature weather and wind and snow, how to make the car pass the winter safely, to avoid the adverse effects of low temperature on the car, we also summarized some experience and precautions for everyone to make a reference.

Some notes on the maintenance of vehicles in winter

1. Check and replace the oil

Motor oil, also known as lubricating oil, is one of the most important supplies in automobiles. Any car needs to use lubricating oil, which can play a good role in lubricating and cooling the engine, and can better protect the engine to make it run more smoothly and last longer. So, let’s talk about what you should pay attention to when using oil in winter.

At present, most motor oils on the market use SAE and other grades to mark viscosity, SAE is the abbreviation of "American Society of Automotive Engineers" in English. For example: SAE15W-40, where "W" means winter (winter), the smaller the number in front of "W", the thinner the engine oil, the better the low temperature fluidity, the better the cold start ability, and it can be used in a lower temperature environment .

Individuals can check the minimum winter temperature in their area and appropriately change the applicable engine oil during inspection or maintenance, which can avoid the difficulty of starting the car caused by the low winter temperature and serve the purpose of engine maintenance.

2. Check the antifreeze and glass water

Glass water is also divided into two types for summer and winter. Before entering the winter, remember to change to glass water for winter. Although it can be replaced with clean water and clean water in summer, these substitutes may freeze in winter, so they cannot be used in winter. In the environment below 0℃ in winter, the anti-freezing winter glass water should be replaced. Alternatively, adding the appropriate proportion of alcohol to the glass water can also achieve the purpose of reducing freezing point and anti-freezing.

Some car owners like to use ordinary tap water as a glass water in the summer, so there is no harm in doing so. The tap water contains many impurities. After a long time, the impurities will adhere to the rubber tube and affect the normal water spray. Long-term use may increase the friction between the glass surface and the wiper blade, and scratches on the glass. In fact, clean water can only simply clean the dust, and it does not have the ability to thoroughly clean the dirt and insect bodies attached to the window. And in winter, don’t forget to replace the antifreeze glass water, and replace the corresponding glass water according to the temperature of your area.

In the cold winter, be sure to use anti-freeze for the winter of the car. Especially the weather in the north is cold, and the temperature is below zero for most of the time. If the engine's cooling system is ordinary water, it will form ice, which will cause the car to fail to start normally, and serious damage to the engine.

3. Check the car battery

The electrode connection point of the battery is a place where problems easily occur during the alternating seasons, so pay attention to maintenance. During the inspection, if green oxide is found at the electrode connection, remember to wash it away with boiling water. If these green oxides are not removed, it will cause insufficient power generation of the generator, and the battery will be in a state of power shortage. In serious cases, it will cause The battery was scrapped early, or the car could not be driven. After being washed away with boiling water, and using compressed air to dry the water, then spray a special protective agent to prevent the oxide layer from appearing again.

4. Check the tires

In the spring and summer, when the tire pressure is too high, the tire pressure should be checked frequently. When the temperature falls in autumn and winter, the air pressure should be supplemented to keep it within the specified pressure range. At the same time, you should also check whether the tire has scratches, because the rubber is easy to harden in autumn and winter, the tire is easy to leak or puncture the tire. As long as the tire pressure reaches the value specified by itself.

5. Check the air filter

Usually the three filters we have heard, in fact their respective names are gasoline filter, oil filter and air filter, and the air filter we are usually also called the air filter, we all know that the operation of the engine requires a lot of Combining the combustion of air and gasoline, the dirty filter element can not achieve good filtration, which makes the engine load heavier. Over time, it will have bad consequences for the engine and great damage to life.

6. Check vehicle lights

The lighting is mainly to check whether the headlights, fog lights, brake lights and turn signals work normally. If one or several items are found to be faulty, it may be that the lamp has reached the end of its life, or the circuit may be faulty. It is recommended to conduct a systematic inspection. Winter rain, snow and fog often appear in winter. Whether the lights are normal or not is directly related to our driving safety.

7. Brake system check

Brake pads are also called brake pads. In the brake system of a car, the brake pad is the most critical safety component. All brakes are good or bad because the brake pad plays a decisive role. Therefore, a good brake pad is the protector of people and cars.

Other considerations:

1. Air conditioning system detection

In winter, when the warm air is in use, the warm air system will fail after a long period of inactivity, so first try to check whether there is hot air, whether the fan is operating abnormally, and whether the air duct is smooth. Sometimes the antifreeze in the warm air pipe does not flow for a long time, and the circulation line is blocked by condensation. Although it does not affect the driving, it is very troublesome to maintain. If you have any problems, you must go to the repair shop in time for repair.

2. Do a "beauty"

Before winter, it is best to do a "beauty" for the whole body of the car. Because the number of freezing and scrubbing vehicles will be reduced after the winter, so waxing in the early winter is a good way to maintain the car paint. In addition, the waxed body is not easy to get wet, and it is not easy to have condensation and ice in winter.

The inspection of the belt can not be ignored. If the phenomenon of slipping or breaking occurs, the related auxiliary machines will lose their functions or their performance will be reduced, which will affect the normal use of the car. The rubber of the belt also has an aging problem. If the rubber of the belt is seriously aging, a new belt must be replaced in time.
