Pay attention to check the heating system.

Winter is the season to use warm air, and all car owners' heating systems have been out of use for a long time. So I suggest you try your car's heating system first, whether the fan works normally and whether the air duct is smooth. Because, sometimes the antifreeze in the warm air pipe does not flow for a long time, and the condensation blocks the circulation pipe. Although it does not affect driving, it is very troublesome to maintain. Therefore, it is recommended that you drive to the 4S shop or repair shop as soon as possible to check the heating system.

Antifreeze should be replaced every two years.

In winter, car owners should pay more attention to checking antifreeze. The amount of antifreeze must be appropriate. It is generally recommended to change antifreeze once every two years, but mixed antifreeze (especially water added in summer) must be changed once a year. Note that different brands and models of products cannot be mixed, followed by engine oil. In winter, engine oil has higher requirements for vehicle lubrication. If it is used in summer, it must be replaced. Oil with long service life, black color and poor adhesion should be replaced to ensure smooth engine start.

Be careful to "bathe" the car

Many car owners like to "bathe" their cars. If it is not properly cleaned, it will damage the bright oil part of the outer layer, resulting in dull wagon. It is best to use a neutral and mild cleaning agent to remove sand and dirt on the surface of car paint. Finally, the tires, bumpers, wheel eyebrows and other parts are coated with corresponding protective agents to prevent aging.
