The cold winter car maintenance and beauty knowledge in the mid-winter season

1. The warm air is used in winter again, and the heating system will fail after a long time of non-use, so you must first try to see if there is hot air, whether the fan is running with abnormal noise, and whether the air duct is unblocked.Sometimes encountered in the heating pipeAntifreezeIf it does not flow for a long time, and the circulation pipeline is blocked by condensation, although it does not affect the driving, it is very troublesome to repair. Therefore, if there is a problem, it must be repaired in a repair shop in time.

2. Need to check the antifreeze. The amount of antifreeze must be appropriate. The maintenance station recommends that the antifreeze be replaced every two years, but the mixed antifreeze must be replaced every year. Note that products of different brands and models should not be mixed. Followed by engine oil.Winter pairCarThe lubrication requirements are high. If the summer oil is used, it must be replaced. If the oil has been used for a long time, the color is black, and the adhesion has deteriorated, it should be replaced to ensure the smooth start of the engine.

3. High-grade gasoline can be replaced in winter. If you usually use 90# gasoline, you can change to 93# gasoline. Because of the low temperature of the car in winter, the ignition point of high-scale gasoline is higher and the ignition ability is stronger. Fourth, although the use of glass cleaning fluid in winter will be significantly reduced, but it can not be ignored. Some people use clean water and clean water instead in other seasons when the dosage is high, but those substitutes often freeze in winter, so they cannot be used in winter. In the environment below zero degrees Celsius in winter, the anti-freezing winter glass washing liquid should be replaced, or an appropriate proportion of alcohol should be added to it to achieve the purpose of reducing the freezing point and anti-freezing.

Fifth, it is best to do a "beauty" for the whole body of the car before winter. Because the weather is freezing after the winter, the frequency of brushing the car will be reduced, so waxing in the early winter is a good way to maintain the paint. In addition, the waxed car body is not easy to take up water, and it is not easy to condense into ice in winter.

Sixth, the black bulbs in the car lights should be replaced as soon as possible, and also checkedFog lights,Brake lightSituation.Frost is easy in winter, visibility is low, and rear-end collisions are particularly frequent, so fog lights, high-positionbrakeWhether the lights work normally is also a guarantee for driving safety in winter.

Seven.AccumulatorMost afraid of low temperature, battery in low temperature environmentCapacitanceThe amount is much lower than the capacitance at room temperature. Therefore, before the onset of the cold season, the electrolyte of the battery should be replenished and the specific gravity of the electrolyte should be adjusted. At the same time, clean the battery terminal and apply special grease to protect it to ensure reliable startup and prolong battery life. If the vehicle is parked in the open air or in a garage for several weeks, the battery should be removed and stored in a warmer room to prevent damage to the battery from freezing.

Eight,TiresIn winter, rubber becomes hard and relatively brittle, and the friction coefficient will decrease.TiresThe air pressure cannot be too high, but not too low. If the outside air temperature is low, the tire pressure is too low, and the soft tire will accelerate the aging process. In winter, you should always clean up the inclusions in the tire pattern, try to avoid using tires that have been repaired more than once, and replace tires with larger wear and different brands and different patterns. The internal and external wear of tires are quite different. To ensure safety and reduce wear, tires should be replaced regularly.Source: Dahe.com
