First, in winter, when it comes to the season of using warm air, the warm air system will malfunction after it is stopped for a long time. Therefore, you must first try whether there is hot air, whether the fan runs abnormally, and whether the air duct is unobstructed. Sometimes antifreeze in the warm water pipe does not flow for a long time. The condensation clogs the circulation pipe. Although it does not affect the traffic, it is very troublesome to repair. Therefore, it must be promptly repaired by the repair shop.
Second, need to check the antifreeze. The amount of antifreeze must be appropriate. The repair station recommends that the antifreeze be changed every two years, but the mixed (especially summer plus) antifreeze must be replaced every year. Pay attention to different brands of different models of products do not mix. Followed by oil. In winter, the requirements for lubrication of automobiles are high. If the engine oil used in the summer must be replaced, the engine oil that has been used for a long time, has a dark color, and has poor adhesion should be replaced to ensure that the engine starts smoothly.
Third, in the winter when you can replace the high-scale gasoline, if the usual use of 90 gasoline can be changed to 93 gasoline. Because the car's ambient temperature in winter is low, the use of high-grade gasoline has a higher ignition point and a stronger ignition capability.
Fourth, although the use of glass cleaning fluid in winter will be significantly reduced, but it can not be ignored. Some people use fresh water and clean water in other seasons, but in the winter, those substitutes often freeze, so they cannot be used in winter. In the winter environment below zero degrees Celsius, anti-freezing winter glass cleaning fluid should be replaced, or adding appropriate proportion of alcohol can achieve the purpose of reducing freezing point and freezing resistance.
Fifth, it is best to do a "beauty" for the car body before entering the winter. Because the number of times of brushing the vehicle will be reduced due to cold weather after entering the winter, waxing at the beginning of winter is a good way to maintain the paint. In addition, the waxed body is not easy to occupy water, and it is not prone to condensation and ice formation in winter.
6. The bulbs that have turned black in the lights should be replaced as soon as possible, and the conditions of the fog lights and brake lights should also be checked. Winter is prone to blooming, visibility is low, and rear-end accidents are particularly high. Therefore, whether fog lamps and high-level brake lights work properly is also a guarantee of driving safety in winter.
7. The battery is most afraid of low temperature, and the battery capacity in the low temperature environment is much lower than that at normal temperature. Therefore, before the advent of the cold season, the electrolyte of the storage battery should be replenished to adjust the specific gravity of the electrolyte. At the same time clean the battery terminals, and coated with special grease to protect, ensure reliable start-up, extend 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 icing damage.
8. The tires become hard and relatively brittle in winter, and the coefficient of friction will decrease. The tire pressure may not be too high, but it must not be too low. Low outside temperatures, low tire pressure, and severe soft tires will accelerate aging. In the winter, it is necessary to clean up the inclusions in the tread pattern, try to avoid using tires that have been repaired more than one time, and replace the tires that have worn more and different patterns from different brands. The wear inside and outside the tire is very different. To ensure safety and reduce wear, the tire should be changed regularly.
