The cold wave is coming，The editor believes that how to maintain cars in winter should also be a topic of great concern to car owners。Because it’s cold，Vehicles are more likely to have problems in winter，Cause more trouble to car owners。Usually we say that cars need "three-point repair，Qifennuang”，means through active inspection and maintenance，To discover and eliminate some initial ones、Potential，Hidden fault。Winter car，Carefulness is the key，Just like humans, we need to keep warm in winter，Cars need more care in winter。Let’s take a look at what precautions should be taken when using a car in winter!

1. Heating system

Whether the heating system can work properly is undoubtedly very important in winter，Although the heating system has a simpler structure than the air conditioning system，But after a summer of inactivity，Faults will also occur。So try the heating system before winter and there is no hot air、Is there any abnormal noise when the fan is running、Is the air duct smooth?。Sometimes the antifreeze in the heating pipes does not flow for a long time，Condensation blocks the circulation pipeline，Although it does not affect driving，It is very troublesome to repair，If there is a problem, be sure to go to the 4S shop or repair shop to repair it in time。

2. Cooling system

Be sure to use antifreeze in winter，The weather is especially cold in the north，The temperature is below freezing most of the time，If there is ordinary water in the engine cooling system，Easy to freeze，Not conducive to starting the car，Almost will cause serious damage to the engine，According to statistics，Cooling system failure is the number one killer of engine failure，Accounts for about 60% of the total number of engine failures!So using antifreeze in winter can effectively prevent the occurrence of freezing events in the cooling system。So don’t forget to check the antifreeze when entering winter。Generally speaking，It is recommended that antifreeze should be changed every two years。But if you have ever added ordinary water to antifreeze，Then the antifreeze replacement cycle should be earlier，Pay attention to the color of the antifreeze when replacing it，Different colors cannot be mixed。

As far as the choice of antifreeze，The lower the freezing point，Undoubtedly, the stronger the antifreeze resistance will be。The freezing point of antifreeze currently on the market is -15℃、-25℃、-30℃、-40℃ and other specifications，The selected freezing point should be more than 10℃ lower than the lowest temperature in the area。

3. Hot car

After igniting the car, wait for a while (the waiting time depends on the relative stability time after the speed drops，Generally no more than one minute)。For example, when the vehicle is first started, the speed is above 2000 rpm，About 30 seconds to 1 minute later，Look at the engine tachometer pointer and it has dropped to about 1200 rpm (but it has not yet dropped to the normal idle speed of 800~1000 rpm)，And it has been basically stable without obvious fluctuations，There is no obvious vibration in the car body，In this case, you can start in gear。Keep the speed within 2000 rpm and drive slowly (without affecting the normal driving of other vehicles)，When the water temperature reaches nearly 60℃ or above (more than one-third of the normal car water temperature gauge), you can drive normally。

4. Water spray system

Even though the usage of the wiper sprinkler system will be significantly reduced in winter，But it cannot be ignored，Especially in the northern region。Same as antifreeze，Although it can be replaced by clean water and clean water in summer，But in winter，These alternatives may freeze，So it cannot be used in winter。In winter seabet myin an environment below zero degrees Celsius，The anti-freeze winter glass water should be replaced，Or you can lower the freezing point by adding an appropriate proportion of alcohol to the glass of water、The purpose of anti-freeze。

5. Full vehicle lighting inspection

In winter, a comprehensive inspection should be carried out on the working status of the entire vehicle's lights，Blackened light bulbs should be replaced as soon as possible。Fog lights、brake light、You should check the working status of the turn signal yourself。Low visibility in foggy early morning winter weather，There are many rear-end collision accidents，So it’s like a fog light、Is the high-mounted brake light working normally，It is also a guarantee of driving safety in winter。

6. Power supply system

Here we mainly talk about batteries。Battery is very "sensitive" to low temperature，The battery capacity in low temperature environment is much lower than that at normal temperature。Although current batteries are maintenance-free，No need to replenish the battery’s electrolyte，Adjust the specific gravity of the electrolyte。But before the cold season comes，The battery terminals should also be cleaned，And apply special grease to protect it，Guaranteed reliable startup，Extend battery life。If the vehicle has been left unused in the open or in a garage for several weeks，The battery should be removed and stored in a warmer room，To prevent battery damage。

7. Tires

Rubber will become hard and relatively brittle as the temperature drops，The friction coefficient will be reduced。In winter，Tire pressure should not be too high，But it should not be too low。Low outside temperature，Tire pressure too low，Soft tires can seriously accelerate aging。In winter, inclusions in the tire tread should be cleaned regularly，Try to avoid using tires that have been patched more than once，Replace tires with greater wear and different brands and patterns。There is a big difference in tire wear inside and outside，Reduce wear and tear to ensure safety，Tires should be dynamically balanced on four wheels regularly，Change tire position。

8. Windshield

Keeping the windshield clear is the basic condition for safe driving。Wiper blades should be wiped regularly in winter，Make sure the windshield can be wiped clean on snowy days。If possible, you can replace the anti-freeze windshield，To avoid freezing in winter。Also，You can add some windshield de-icer to the glass water。When the windshield is frozen，Spray the glass with water，Ice can melt，Not like ordinary glass of water，The more you spray when it freezes, the more trouble you get。

The rear window glass defogging circuit plays a great role，Driving in rainy or snowy days，The rear window defogging circuit can quickly remove fog or ice water，Thus providing the driver with good rear visibility。During maintenance，The window glass should be wiped along the direction of the printed lines，That is, wiping horizontally，If wiped up and down，Easy to break the resistance wire。If you need to check whether the defog line is working，You can turn seabet loginon the rear window defogger switch，See if you can clear the fog from the rear window，If it cannot be cleared，You should first check whether the fuse of the rear window defogger circuit is intact，If the fuse is OK，Check again whether the printed circuit on the rear window glass is broken，If there is a disconnection，Should be sent to a repair shop for repair，Or use a clean cloth to wipe away the moisture and dirt on the broken part，Cut the tin foil used to wrap cigarettes into appropriate sizes，Then stick the tin foil on the transparent tape，And keep the side of the tin foil facing out，Finally, just paste the tin foil on the broken line。

9. Chassis

Due to the heavy snow, there is a lot of steam，Sometimes in order to melt the ice and snow as quickly as possible，Snow plows often spread large amounts of salt on the road to speed up the melting of snow and ice。The road surface is equivalent to a layer of acidic liquid road surface，Car driving on ice and snow，The flying tires will obviously throw the highly salty snow water onto the car chassis，If the chassis is not protected, it will easily lead to corrosion and rust of the chassis。So，You'd better take some time before winter begins，Provide anti-rust care for the chassis。To better protect your car。It can also extend the service life of your car。

10. Air intake system

When entering the cold winter season, the car may often fail to start。Except maybe due to insufficient cooling system and battery power，Most of the reasons are due to the throttle、Caused by excessive carbon deposits in the intake duct, etc.。Excessive carbon deposits on the throttle itself can easily cause failure to ignite，Throttle valve carbon deposits may not affect engine starting in summer，But in winter, the temperature of the car environment is lower，Gasoline volatilization is affected，The ignition ability of gasoline is relatively weak under the same equipment condition，The engine may fail to ignite，Or multiple ignitions are required。So it is recommended that car owners clean the engine throttle valve carbon deposits in winter，Under normal circumstances，The editor recommends cleaning the throttle body and checking the spark plug every 20,000 kilometers or so，It can prevent the engine from catching fire。

11. Lubrication system

It is well known that engine oil has lubrication properties、Cooling、Three major cleaning functions，The normal flow of engine oil is an important medium to ensure the normal operation of the engine。However, the realization of these functions is mainly determined by the viscosity of the engine oil、Liquidity related。The viscosity of engine oil will change with temperature changes。

Be sure to choose the appropriate viscosity when changing engine oil in winter，Different viscosity levels are suitable for different ambient temperatures，If you choose incorrectly，It is easy to cause difficulty in starting the car engine，Even unable to start and other problems。Improper engine oil will increase the working resistance of the engine，Intensify the wear of mechanical parts and increase fuel consumption。Correct choice of engine oil，It will seabet appundoubtedly increase the service life of the engine。

12. Wiper

When driving to work in the morning in winter, you often find a thick layer of fog or frost on the car windows，Sometimes the wipers even get frozen to the glass，Never force open the wiper at this time，Not only destroys the wipers，It also damages the glass，Never use hot water to rinse the glass directly，This can easily cause the car window to burst、Wiper deformation!

At this time，You can start the engine first，Turn on the warm air defogging mode and blow the front windshield，The fog on the glass disappears after a while，The wipers will naturally separate。If it’s too slow，Usually, you should add antifreeze glass water to the wiper spray bottle，The wiper can be propped up if necessary，Also use special anti-fog agent，Apply evenly on the inside of the glass，It can prevent fogging for about four or five days at a time。

For rear window defogging，You can turn on the rear windshield resistance wire defogger on the car，This feature is also standard on most vehicles，The specific usage is very simple，For most vehicles, just find this button on the center console and press it，Please pay attention to check frequently。

13. Choose a suitable location to park

Bad winter weather，Windy weather、Rain and snow weather are always sudden，To ensure that your car is not damaged by temporary weather changes，Pay attention to choosing appropriate parking spaces。

Summary: The editor believes that cars should be carefully maintained in winter，Because the temperature is very low，The parts of automobile parts are relatively fragile，Use it carefully to protect your car。I hope these thirteen details will be helpful to everyone。
