In cold weather, you must not ignore the small knowledge of car maintenance

You are wrapped in a jacket under the northern sun

I shivered in the cold south wind

Everyone wants to teleport to the car when they go out, and say unmodestly

On the way to work, my life is allcargiven

"Re-creation grace" for this unrequited

The best reward is of course to do winter maintenance for the car

Let's discuss the little knowledge of winter maintenance~

Rain and snow

""Armor" can only corrode fearlessly by adding body

The rain and snow in winter will not only cause inconvenience to transportation, but also have hidden arrows.This is becauseRain and snow contain acidic or alkaline substancesIt will destroy the protective layer on the surface of the car body, make it lose its luster, and even damage the paint surface in severe cases.

If you want your car to be protected from harm and always have an online appearance, you must do a good job of body maintenance for your car.WaxingIt is a good choice.Waxed car surface can makeThe water droplet adhesion rate is reduced by 60% to 90%, Greatly reduce the damage of rain and snow to the paint; also can chooseSeal the glaze,it hasAnti-acid rain, anti-corrosionIt can prevent the car paint from being corroded, and its durability is longer than that of waxing.

It's cold and the car is cold

Focus on the cultivation of "core" in order to move forward courageously

①The right way to warm up

The sudden drop in temperature will not only increase the burden on people, but also increase the burden on the “heart” of the car—the engine.The right way to warm upespecially important. In life, many people only know about hot cars, but they can’t tell why they want hot cars.

In fact, the main reason for the hot car is: after the car was parked for one night, the upper part of the engine oil ran back into the engine oil pan. After ignition, there needs to be a reasonable "wake-up" time to allow the oil to reach the "work". "Post" to avoid serious engine wear.

Although the hot car is important, it cannot be excessive. What is the right thing to do?

The correct way to warm up the car is: the car starts30 seconds to 1 minuteAnd then keep driving at a low speed, the engineRotating speedDo not exceed 3000~3500 revolutions,It is advisable to keep the speed at 2000 rpmAfter the engine temperature rises to the normal temperature, the original driving habits can be restored. Remember not to leave the car, this will increase the wear of the engine and the gearbox, and will not cause problems in a short period of time. Over time, the engine will "suffer".

②Change the antifreeze in time according to the temperature

In addition to mastering the correct way to heat the car, replace it in timeWater tankinnerantifreezeIt is also a method.When replacing, the owner needs to pay attentionDifferent antifreeze liquids cannot be mixed, In order to prevent the occurrence of chemical reactions to produce precipitation and bubbles, which will affect the use effect; when added,It is advisable to keep a distance of about 10mm between the liquid level and the water tank filling port.

③Choose the right lubricant

Choose the right onelubricating oilIt can also reduce the burden on the engine. When opening the oil port in the engine to add lubricating oil,The oil volume should be controlled between the upper and lower scales of the oil dipstickFor good, the selection should also be based on the performance of the car, as far as possibleChoose a lower consistencyOf lubricants.

As the temperature drops, ordinary lubricants willBecomes more viscous and fluidity becomes worse, It takes longer to reach each part to be lubricated, which makes the vehicle difficult to start and increases engine consumption. The replacement of lubricating oil is relatively complicated and professional. It is recommended that car owners choose to go to the nearest special store for professional care~

Slippery road

"Limbs" are stable to go further

When traveling in winter, it is not uncommon for roads to be slippery due to fog, rain, frost, and snow. As the "hands and feet" of the car,tireIt directly affects the driving experience, stability and safety of the car, sotireThe maintenance cannot be ignored.

As the temperature drops, rubber will become relatively hard and brittle,Reduced friction coefficient, Thereby increasing the risk of car out of control, so the car should pay special attention to the tire pressure of the tires. The standard tire pressure should be maintained and cannot be increased or decreased at will. If you are not at ease, when the temperature is expected to continue to drop, you can increase the tire pressure by 0.1- 0.2bar. In addition, in winter, it is necessary to frequently clean up the debris in the tire pattern, try to avoid using repaired tires, and change the position of the tires regularly to reduce travel risks.
