With the increasingly cold temperatures, vehicles are also facing the icy test. It's especially important to take good care of your car before you get into the winter. If you don't spend the winter well, it's hard for you as a car owner.
In December, the warm winter sun in the early winter in the northeastern part of northeastern Sichuan has added a bit of color to the cold winter days. However, from yesterday, the six cities in northeastern Sichuan were generally cooled, and the cold air brought even more drizzle, prompting everyone to see the winter season. In addition to caring for people, adding antifreeze, and skin care and beauty, the car also needs maintenance in the winter to adapt to a climate of change, to improve driving comfort in cold and humid driving environments in winter and on frost-smooth roads that are easy to skid. The safety performance.
Inner body
Oil, battery, air conditioning is the key
Oil: The winter season is a harsh season. After the temperature drops, the viscosity of the oil will increase. Therefore, before entering the winter, you should change to a high-quality, high-efficiency lubricant. The core idea of ​​contemporary car care is the use of high-quality motor oils, antifreeze fluids and corresponding additives. The fluid change work should be performed at a special site or a reliable professional maintenance center. The general antifreeze is valid for 3 to 4 years. It is not necessary to replace the antifreeze after every year. However, antifreeze should be inspected before the winter arrives. It is best to designate a maintenance shop and have someone do the inspections instead of adding antifreeze. The owner can visually inspect the appearance of the vehicle. If the antifreeze fluid is thickened, turbid, deteriorated, smelling, foamed, or less, it should be promptly replaced or repaired. Because the antifreeze will cause the freezing point to rise once it fails, in the winter when the temperature is too low, it is extremely easy to damage the water tank or even the engine due to freezing.
Battery: The life of a typical battery is two to three years. If it is near the end of its useful life, it is better to replace it with a new one, because the current maintenance-free battery has no symptoms before it is bad. The inspection and maintenance of liquid batteries is even more important. First, check the battery case for leakage of electrolyte. If there is leakage, the battery should be replaced; if there is no leakage, the surface of the battery and the oxide on the battery post should be cleaned with hot water, but be careful not to let the water enter the inside of the battery from the ventilation hole. After the water is dry, it is best to use sandpaper to clean the contact surface between the pole and the connector, and tighten the fixing screw on the connector to ensure that sufficient current passes through the connector. Second, check the battery voltage. The method is: When the engine temperature is normal, when the starter technology is in good condition, the engine can start smoothly several times in succession, indicating that the battery is in good condition and the voltage is normal. If every start, the engine speed gradually decreased, or the engine is barely able to start, indicating that the battery voltage is in a depletion state and should be charged. Third, check the specific gravity of the electrolyte and the height of the liquid surface. If the proportion of electrolyte is too low, first, it cannot provide enough electric energy, and second, it may crack and crush the outer shell. It should be noted that after the battery is fully charged, the sulfuric acid concentration in the electrolyte is adjusted. An excessively high concentration of sulfuric acid will shorten the life of the battery. The electrolyte level should be 10 to 15 cm above the upper edge of the plate. When height is not enough, distilled water or battery replenishment should be added. Do not directly add electrolyte or tap water. This will immediately cause the destruction of the battery.
Air Conditioning: In the winter, the refrigeration system of the car air conditioner will be parked for a long time. However, if it is used for a long period of time, its moving parts will have a phenomenon of “stabbingâ€, which will increase the starting resistance torque, causing the air-conditioning electromagnetic clutch to slip, excessive wear, and will make the shaft seal dry and sticky and fail, resulting in leakage. Therefore, the main points of winter maintenance of automotive air-conditioning refrigeration system are: The air-conditioning refrigeration system is started 2-3 times a month, about 10 minutes each time. This consumes less fuel, but it avoids major losses of evaporators and compressors. Starting the refrigeration system can choose to open for 10 minutes while driving on a sunny day when the temperature is above 10°C. It should be reminded that many automobile air conditioners are equipped with temperature control circuits. When the ambient temperature is lower than 10°C, the electromagnetic clutch current of the air conditioner compressor will be automatically cut off and the refrigeration system will not work, instead of the failure of the refrigeration system.
Outside care
Tires, chassis, sunroof need attention
Tires: Frost and snow tires tend to slip, because the grooves of the tires may have been too shallow to drain quickly, so the tire safety should be noticed during the frost and snow season. It is also important to control the speed.
1. At least once a month, check the pressure of all tires (including spare tires) under cooling. The pressure value is based on the information provided by the automobile manufacturer.
2. Regularly inspect the condition of the tire. If any damage is found or the tread is worn irregularly, it must be checked immediately by a professional.
3, tire wear to wear indicator, should stop using. 4. Only professionally trained personnel can install the tires and balance the tires and rims.
5, if you find tire tread irregular wear or vehicle shake, please check the wheel alignment and balance immediately.
Chassis: Chassis is the part that is closest to the ground except the tires. The muddy water that splashes in the rain hides in the crevice of the chassis. The owner usually does not pay attention to the chassis cleaning. The humidity and mud will cause corrosion to the chassis. The owner should always Pay attention to the cleanliness of the chassis, it is best to go to the chassis of the large car department store to make a chassis armor, completely cut off from the outside world.
Sunroof: 1, due to the higher temperature inside the vehicle caused by melting snow and ice around the skylight, and overnight after the start can easily make the sunroof glass and sealant box frozen, such as forced open the sunroof so easy to damage the sunroof motor and rubber seal, to wait for the car Increase the internal temperature and confirm the thawing before opening the sunroof.
2, winter car wash, even if the hot water car wash if not fully wiped, the vehicle in the driving edge of the skylight will remain frozen, so after the car wash should open and close the sunroof to dry around.
3. After the surface of the sunroof sealing strip has been painted or flocked, in order to avoid freezing, it is best to dry the painting strip with a soft cloth and apply some talcum powder. The flocking tape (with black velvet on the surface) can be wiped dry, do not stick with oil.
4. The electric sunroof is equipped with slide rails. During the winter, the slide rails should be regularly cleaned around to avoid sedimentation of sand, and a small amount of oil should be applied after cleaning. Do not lubricate.
Paint: Rain and snow all contain acid reduction, which has a corrosive effect on the paint surface. It will accelerate the fading and cracking of the paint surface. It is the best choice for car paint to be maintained. Car wax contains petroleum components, which will be lost when water is encountered. Car waxes remaining on the lacquer watch will not only fail to protect the car paint but will also form an “oxidation resonance†with the paint surface. The best method is to make an electrophoretic coating on the paint surface. The electrophoretic coating is inorganic, it will not corrode the paint, and the protection time can be more than 3 years, so that the paint stays bright for a long time.
Winter safety
Reflector and brake system need to be checked
Mirrors and windshields: It is terrible to drive snow covered with frost and snow on the reflectors. This means that you cannot see the status of the car. If you are not careful, you may “followâ€. In fact, the glass affected by frost and snow is not only a mirror, but also includes front and side windshields. The glass is obscured by frost and snow. If it is not cleared in time, it will threaten traffic safety. The usual practice is to Special anti-frost agent is sprayed on the glass to achieve clear glass.
Braking system: pneumatically braking vehicles, it is necessary to reasonably adjust the pre-tightening force of the balance spring in the master cylinder. If the preload is too large, a “hard†feeling will occur during braking, and an emergency brake will be applied as soon as the brakes are applied. This type of braking is prone to accidents in the winter. Hydraulic brake vehicles, but also pay attention to check the brake oil, brake lines and brake cylinders with or without leakage, if any leakage, it should be promptly replaced brake fluid. Also adjust the hand brake. Its braking action is based on the mechanical transmission acting on the drive shaft. 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. In other words, when braking by hand on an icy road, it is possible to prevent flicking, thereby reducing the chance of an accident. The inspection of the handbrake requires the sound of the lock block not to exceed three sounds when the handbrake is pulled. If it reaches five sounds, it means that the hand brake gap is too large and must be adjusted to reduce the free travel and effectively ensure safety.
