Routine maintenance in winter to keep your car unobstructed in the cold

As the temperature gradually drops, starting difficulties and other problems that only occur in winter begin to appear frequently. How to maintain your car? How to refuel? How to avoid annoying problems when driving in the morning? Perhaps this article can offer some tips for car owners and friends.

First, start quickly-check the battery

The temperature in the morning is relatively low, and it will be difficult to start the car overnight. At this time, checking the status of the battery becomes an indispensable content. Generally speaking, there are two types of batteries: water-free type and water-added type. The former uses the color change of the checker attached to the battery to judge the working state of the battery during the inspection, while the latter uses the battery water level as the basis for inspection. Although the water-free battery is convenient, its life is shorter than that of the water-filled battery. The performance gradually deteriorates after about one year of normal use. It can be regarded as normal if it can be used for two years. Water-filled batteries have the advantages of cheapness and durability, and can be used for more than two years. However, if you forget to add replenishment regularly, the life will be shorter than that of water-free batteries. Water-filled batteries require frequent checks of fluid volume.

When getting out of the car, be sure to look back to see if the lights are turned off. The type of the anti-theft device that consumes a lot of power should also be avoided as much as possible, so as not to end the life of the battery early. When getting out of the car, it is best to ignite the engine to work before driving lights, radios and other electrical appliances. When parking, turn off all electrical appliances before turning off the engine. When the ignition cannot be started, wait for about 30 seconds to start again, avoid upset and irritable, and continue to ignite to prevent the exhaustion of electrical energy.

If the lights become dim when you stop at a red light at night, the lights will be brighter when you step on the accelerator, and the engine will start to slow down slowly. This means that the battery life will be exhausted and you must replace it with a new one. .

2. "Blood veins are unobstructed"-changing oil

In the cold winter, the car needs more protection, not only to change the engine oil, but also to replace the engine water tank antifreeze.

The lubricating requirements for automobiles in winter are high. As the temperature drops, the fluidity of the engine oil will deteriorate, resulting in increased frictional resistance during the movement of the parts, difficulty in cold starting, and even burning of the tiles and the shaft. Therefore, when winter comes, you should Change the engine oil to the engine oil for winter in time, and the engine oil that has been used for a long time, the color is black, and the adhesion is deteriorated should be replaced to ensure that the engine starts smoothly. Engine oils of grades above 20W are called summer oils, engine oils of 15W are called season oils, and engine oils of 10W or less are best used in winter.

The antifreeze of the engine water tank also needs to be distinguished. If the antifreeze is a long-acting four-season universal type, it can be replaced every two years or so, but check the concentration and amount. If not, replace the antifreeze solution by draining the water, idling for a few seconds to completely drain the old liquid, and then adding the new antifreeze solution. At the same time, don't forget to replace the gasoline filter for it, so as to reduce the influence of gasoline impurities and moisture on the oil circuit, and it is easier to get on the car in winter.

3. "Powerful undercarriage"-adjusting tires

Due to the special climatic conditions in winter, the requirements for driving and braking of the car are relatively high. Owners should always pay attention to whether the performance of the tire and the brake is in an ideal state during the winter use of the car.

The rubber of winter tires will become harder, more brittle, and the coefficient of friction will decrease. At this time, the tire pressure should not be too high, but it should not be too low. Otherwise, the external temperature is low, the tire pressure is too low, and the soft tires can seriously accelerate aging.

In terms of braking, pay attention to whether the brake fluid is too low, too dirty, or contains water. Using inferior brake fluid that does not meet the original manufacturer's requirements will cause the braking distance to increase or the brake to fail. Automobile manufacturers generally require that the brake fluid must be replaced every two years. However, many car owners believe that private cars only travel less than 20,000 kilometers within two years. Like new cars, it is not necessary to change the brake fluid.

The brakes and brake linings are most closely related to braking. It is necessary to go to the service station to check the thickness of the friction plate regularly, and also check whether the brake friction plate is broken or the brake cylinder has oil leakage.

Finally, you need to adjust the handbrake. The braking effect of the handbrake is on the drive shaft by mechanical transmission. When braking, the braking force is evenly distributed on the two rear wheels through the two half shafts, which can effectively prevent the braking deviation of the two rear wheels. That is to say, when the hand brake is applied on the ice and snow road, it can prevent tail flicking, thereby reducing the chance of accidents.

4. "Adjust Breathing"-Maintain Warm Air

In winter, the temperature outside the car will be relatively low, and many people will turn on the warm air as soon as they get into the car and start the car. At this time, if you listen carefully, you will feel that the car's sound is not quite right, and then slowly open and resume It's normal, why is this? The reason is that the car heater uses hot water in the warm water tank, so don't rush to turn on the warm air when driving in winter, let the temperature of the water tank reach 70 degrees Celsius to 80 degrees Celsius, and then turn on the warm air. There will be no disturbing sounds.

Finally, remind the majority of car owners friends that it is best to replace high-grade gasoline in winter, because the temperature of the car in winter is lower, the ignition point of high-grade gasoline is higher, and the ignition ability is stronger, which will also improve the driving time. Comfort.
