How to maintain a car in winter?
In the cold winter, there are many bad weather such as rain, snow and fog, and the road surface has become more and more complex. Drivers and friends should always pay attention to maintaining their vehicles. So, how to maintain a car in winter? Here are 10 winter car maintenance tips for you.
1. Wiper
If you drive north, in the northern region, if you go out early in the morning and find that the wiper is stuck to the windshield by snow water, do not rinse it directly with hot water, as it is easy to cause the window to burst and the wiper to deform due to temperature changes. The correct way is to turn on the air conditioner to hot air, and the blowing mode is the front windshield, and wait for the wiper to naturally melt away.
2. Cooling system
In winter, it is necessary to regularly check whether the water tank, water pump and belt, water pipe, water tank and other components are working properly. If there is any damage or failure, it is best to repair or replace it in time. Otherwise, a bucket of antifreeze may be wasted for a small water pipe. Especially in some cars, the water temperature is high in summer, and the repairman removes the thermostat. Although it can solve the problem in summer, it will be reversed in winter.
3. Warm air
The warm air that has been placed for a summer often malfunctions. It is best to try whether there is hot air, whether the fan is running abnormally, and whether the air duct is unobstructed. Sometimes the problem is that the antifreeze in the warm air pipe does not flow for a long time, and the condensation blocks the circulation pipeline. Although it does not affect the driving, it is very troublesome to repair.
4. Antifreeze
Many southern drivers generally do not have the habit of checking antifreeze, but when driving to the northern region, you should pay attention. Check whether there is a lack of liquid, whether there is deterioration, and if necessary, replenish or replace it in time. Antifreeze may seem small, but it has a great impact on the car. If it is light, it will block the pipeline, and if it is heavy, it will corrode and damage the cylinder. So choose antifreeze carefully. First, do not mix it, and second, do not use counterfeit and shoddy products. In addition, in general, antifreeze should be changed every two years. It is best to rinse the cooling system with water before replacement.
5. Motor oil
Check whether the label is low temperature, missing or deteriorated. Cold car oil in winter is too thick, which will affect the start-up and increase the wear and tear of the parts. At the same time, hot car oil is too thin will reduce lubrication and sealing performance. Choose high-quality compound oil suitable for winter. If it is at or near the specified oil change time, it is best to change it before the weather gets cold.
6. Windshield
The windshield glass is kept clear is a basic condition for safe driving. Wipers should be scrubbed regularly in winter to ensure that the windshield can be scraped clean on rainy days. In addition, some windshield deicing agent can be added to the glass water. When the windshield freezes, spray the glass water on, and the ice will melt. Unlike ordinary glass water, the more troublesome it is to spray when it freezes.
7. Body
Before winter, it is best to add a protective film to the car body. Car paint coating or mirror glaze containing Teflon polymer can resist the erosion of acid rain fog. Driving to the northern region, when encountering salt water on the road after snow, the salt water splashed on the body is very harmful to the car paint, so pay attention to cleaning.
8. Chassis
In winter, the chassis of a car is always directly exposed to rain, and it is easy to rust. The speeding tires will throw muddy water on the chassis of the car. After the rain clears, the chassis of the car starts to rust. Therefore, it is best to take some time to rust-proof the chassis before winter.
9. Battery
Batteries are most afraid of low temperatures. The capacitance of batteries at low temperatures is much lower than that at room temperature. Therefore, before the cold season comes, the electrolyte of the battery should be replenished to adjust the specific gravity of the electrolyte. At the same time, clean the terminal of the battery and apply special grease to protect it to ensure reliable start and prolong the battery life. If the vehicle is parked in the open air or cold storage for several weeks, the battery should be removed and stored in a warmer room to prevent the battery from freezing and damage.
10. Tyres
Tire rubber will become hard and relatively brittle in winter, and the coefficient of friction will decrease, so the tire pressure should not be too high, but not too low. The external temperature is low, the tire pressure is too low, and the soft tire can accelerate aging seriously. In winter, it is necessary to clean up the inclusions in the tread frequently, try to avoid using tires that have been repaired more than once, and replace tires with larger wear and different brands with different patterns. The wear inside and outside of the tire is very different. In order to ensure safety and reduce wear, the tire should be changed regularly.
