The temperature is very low in winter. How to maintain your car?

Although winter in Beijing is not as cold as that in the northeast, the extreme temperature at night is still very low, especially in the suburbs, which often drops to about-15 degrees Celsius. Cars, like people, are prone to "cold and fever" in cold winter.

Question 1: The keyhole is frozen.

This is mainly because water entered the lock hole, and the inner lining of the door was removed, and the waterproof plastic plate was not glued firmly, resulting in melted snow water flowing into the lock hole along the glass.

Solution: You can pour it with hot water and blow it with a hair dryer. There is another good way. Go to the repair shop in advance to find some rust remover (a special loose rust remover) and spray it into the keyhole to ensure that there is no problem all winter, which is both antifreeze and rust-proof, and it is easy to thaw; Another method is to use special keyhole deicing lubricant.

Question 2: The windshield is frozen.

When the windshield freezes, most people use hard scraping. Although many cars have the function of windshield heating, office workers can't afford the time.

Solution: Just stick a newspaper on the windshield after parking, which is very convenient. The whole work takes less than 1 minute.

Question 3: antifreeze does not prevent freezing.

Some car owners added antifreeze to the water tank, but it still froze.

Solution:

1. Check the antifreeze with a freezing point tester, and don't trust eye recognition;

2. Always pay attention to the water temperature. If the thermometer shows high temperature, turn on the heater and watch the blowing wind. If the heated air is cold, check whether the cooling system is frozen.

Don't boil the water tank cover if the water pipe above is frozen. When the engine is turned off, pouring hot water into the frozen water pipe will make a tinkling sound (proving that the ice has melted).

Question 4: It is difficult to shift gears.

It is difficult to shift gears mainly in cars with manual gears, because the transmission lubricant is too sticky and the gears are difficult to slide, so it takes a while to shift gears.

Solution: Check the quantity and quality of oil. The situation of automatic gearbox is more serious. The vehicle does not move after shifting, especially after driving 80,000 kilometers, which is easy to appear. The main reason is that the oil is too viscous and the oil pressure is difficult to establish.
