Car winter maintenance must know little things

1. Motor oil has high requirements for the lubrication of automobiles in winter. If the engine oil is used in summer, it must be replaced. For engines that use for a long time, black color, and poor adhesion should be replaced to ensure the smooth start of the engine.

2. The amount of antifreeze antifreeze must be appropriate. The degree and type of antifreeze should be taken into consideration in different regions and different models. The antifreeze used for more than two years should be replaced. The mixed antifreeze must be changed every year. Pay attention to different brands of different models of products do not mix.

3, the battery inside the battery can not be deficient, to maintain the plate is submerged 10 mm as well, and check the proportion of electrolyte, to maintain the charge, if the battery is not fully charged, easily cracked in the cold.

4. The brake system should pay attention to whether the brake fluid is enough and whether the quality deteriorates. If necessary, it should be filled or replaced in time. Pay attention to whether the brake is weak or running. If necessary, clean the entire brake system piping section.

5, four-wheel alignment Winter roads are prone to ice and snow, while rubber, metal, plastic and other materials become hard at low temperatures, the control system is also a corresponding reduction in the road feeling weakened, four-wheel positioning is not easy to affect safety.

6. Tire rubber becomes hard and relatively brittle in winter. Not only does the friction system decrease, but it also leaks and punctures more easily than other seasons. In the winter, you should always clean up the inclusions in the tread pattern. Try to avoid using tires that have been repaired more than once. It is also important to replace the tires that wear out and have different patterns in different brands.

7, warm air to check the heater line and fan, in particular, pay attention to the windshield under the defrost outlet outlet is normal, the heat is enough, the windshield defrost outlet problem in the winter driving will bring a lot of trouble and insecurity factor.

8. The use of glass cleaning fluid in the winter is obviously less than other seasons, but it cannot be ignored. Some people use clean water and washing water instead of cleaning fluids in other seasons, but in winter, those substitutes are often used. It is frozen, so it cannot be used during the winter season. Be sure to replace it with a glass cleaning fluid that is not afraid of freezing. You can also add alcohol or liquor to the water to reduce the freezing point.

9, air conditioning autumn air conditioning is not used, but the winter must check whether the air conditioning system is clean, there is no plugging water phenomenon, and at the same time every week must be opened for about 5 minutes, so that parts can be lubricated to prevent hose hardening.

10, waxing into the cold after the winter cold, brushing the number of vehicles will be reduced, so the beginning of winter waxing is the best way to maintain car paint. In addition, the waxed body is not easy to be exposed to water, and it is not prone to condensation and ice formation during the winter.

11, preheating temperature in winter is low, the increase of viscosity of the oil is not easy to flow, after the engine is started, the engine should be kept at about 1100rpm/min, so that the car is warmed up before starting. Do not step on the throttle and do not let the engine speed too high. Preheating does not have to wait until the engine temperature rises to the optimum temperature before starting, as long as the pointer on the thermometer starts to rise.

12, starting in the winter must be soft and slow start, this one is to make the engine not reach the normal operating temperature when the load is as small as possible, on the other hand, so that the tire is not in the heat is still in a hard state with a hot The process has benefits for the engine, tires and safety.

13, shift the winter car shift shift to be diligent, like driving the same period as the driving car, we must pay attention to the choice of gear and oil from the fit, the gear is too low and easy to make the car out of control, which is on the ice and snow It is particularly important to drive on.

14. Braking The winter driving brake highlights an “early” character and a “soft” character. Even if it is on a road without ice and snow, the effect of winter braking is not the same as in other seasons. It is often somewhat “hard”. , so the winter driving brake should be lightly stepped on earlier, combined with the deceleration brake better. On the snow and ice road, the brakes are not applied as much as possible, and the engine is braked by applying a downshift. If necessary, you can also use the hand brake, but you should press the release button of the hand brake, do not let the hand brake stuck. Don't forget that when you are on the road and when you stop and then get on the road, you must try to brake with a few feet to prevent the brakes from failing due to freezing.

15, parking parking in winter should pay attention to the choice of locations, try to avoid the damp pits, so as not to accumulate water to freeze the wheels. In addition, when you have snow and ice, you must choose to park on the ground. You should not park on the slopes to avoid starting difficulties. Avoiding the deciduous place with litter, the car equipped with a three-way catalytic device should pay more attention to preventing the high-temperature three-way catalytic converter from igniting withered grass.
