A way to prevent freezing

Change the lubricating oil in time to ensure smooth operation of the machine parts. After climate change, the viscosity of the lubricating oil will also change, which will generally aggravate the wear of the parts, thus causing the engine and other important parts to be damaged in varying degrees. The lubricating oil has higher requirements for automobile lubrication in winter, and the lubricating oil is divided into winter lubricating oil and summer lubricating oil. Experts suggest that winter lubricating oil should be replaced as soon as possible Oil. Moreover, whether in Guangdong or in the north, the lubricating oil should be changed. Especially for the use of a long time, black color, poor adhesion of the engine oil should be replaced to ensure smooth start-up and operation of the engine.

Experts also suggest that high-scale gasoline can be replaced in winter, and 93 oil can be replaced if the normal use is 90 gasoline. Because the vehicle environment temperature in winter is lower, the ignition point of high-scale gasoline is higher, and the ignition ability can be stronger.

The second way to prevent freezing

Change the engine antifreeze. It's easy to start a fire in the snow and ice. When driving in winter, you need to check the antifreeze. The amount of antifreeze should be appropriate. Engineers suggest that the engine antifreeze should be replaced, especially the mixed antifreeze (especially the one with water in summer).

If the concentration of antifreeze in the engine cooling water is too low, the engine water will freeze, causing the vehicle unable to start in the morning. Therefore, it is necessary to increase the concentration of antifreeze solution, which is generally kept at 70%. Even in the south, it is necessary to increase the concentration of antifreeze solution. One bottle is usually added, and two bottles are needed at this time, generally no more than 50%. In this way, whether in Guangdong or driving to the icy north, you don't have to worry about the car can't start.

In addition, experts remind that it is necessary to pay attention not to mix different brands and models of products, but also to choose different regular brands of antifreeze according to the model. If you choose poor antifreeze, it will not only increase the water temperature, but also corrode the engine. In addition, winter is the season to use warm air. After the warm air system is stopped for a long time, it will also break down. Therefore, the car owner should first try to see if there is hot air, whether the fan is running abnormally, and whether the air duct is unobstructed. Sometimes, the antifreeze in the warm air water pipe does not flow for a long time, and the circulating pipeline is blocked by condensation. Although it does not affect the driving, it is very troublesome to maintain it. Once these problems are found, they should be dealt with in time.

The third way to prevent freezing

Always pay attention to check the tires. In winter, the rubber will harden and the friction coefficient will be reduced. Therefore, the tire pressure should not be too high, but it should not be too low. The external temperature is low, and the tire pressure is too low. The soft tire can accelerate aging, and increase the contact between the tire and the ground, which will accelerate the friction and reduce the tire life.

In winter, it is necessary to clean the inclusions in the tread, avoid using the tire which has been repaired more than once, and replace the tire with large wear, different brands and different patterns.

What to do with the ice on the window? Countermeasure 1: to remove the ice, you can start the engine first, turn on the warm air in the car, and then slowly remove the ice from the ice crevice with a special ice shovel for automobile glass. The correct way to wash the car is to start the car, turn on the heating system, and then clean the car with warm water.

If you take a hot bath after snow, it will cause damage to your car, because the sudden change of temperature will damage the paint and make it lose luster gradually, and the windshield of the car may burst in the pouring hot water. Washing the car with cold water can not be directly washed, especially after the engine is heated up, the temperature of the front part of the car is high. Washing with cold water will cause rapid cooling, which is unfavorable to the surface paint.

Countermeasure 2: try to open the doors on both sides for ventilation after using the car in one day. When the temperature inside the car drops to the same as that outside the car, turn on the power supply and use the wiper to clean the residual water on the windshield. Then close the door and lock the car. The next morning you can drive on the road.

The reason for the glass freezing is that after people leave the car, there is still hot air in the car. When the temperature inside the car gradually drops to the same as that outside the car, the water vapor inside the car begins to freeze.

Protective Preparation Tips

1. Replace the black light bulb as soon as possible, and check the condition of fog lamp and brake light. It is easy to fog and frost in winter, and the visibility is low. Whether the fog lights and high brake lights work normally is also the guarantee of driving safety in winter.

2. If the destination of self driving tour is mostly ice area, do a "beauty" for the whole body of the car nearby. Waxing at the beginning of winter is a good way to maintain the paint. In addition, waxed car body is not easy to get water, and the phenomenon of condensation into ice will not occur easily in the low temperature area in winter.

3. When driving to Hunan or further north, you should pay attention to the problem of glass water. Although the glass cleaning agent will obviously decrease in winter, it can not be ignored. Some people use clean water and washing water instead in other seasons, but those substitutes often freeze in winter, so they can't be used in winter. In winter, the antifreeze winter should be replaced in the environment below 0 ℃ Seasonal glass water, or more simply, adding appropriate proportion of alcohol in glass water can achieve the purpose of reducing freezing point and frost resistance.
