In winter, the maintenance and use of cars is also entering a critical period. Especially in the cold and misty city of Chengdu, cars are prone to “winter diseaseâ€. How do friends with cars do “tonics†for cars? For the readers of the hot issues, "car 114" grand launch of winter car maintenance Raiders, from the body, tires, engines, chassis, interior, etc., to provide owners with a comprehensive maintenance and maintenance knowledge.
The engine is the heart of the car and its importance for winter maintenance is self-evident. In this issue of 114 cars, first talk about engine maintenance and maintenance. Experts remind owners to use high-end synthetic lubricants and replace antifreeze in time when servicing engines in winter.
Reduce wear and tear to prevent heart failure
Key point: use high-end synthetic lubricants
The engine is the heart of the car, and the lubricating oil is the top priority of the engine maintenance. When the winter comes, the viscosity of the general lubricating oil will decrease because of the temperature, and the fluidity will deteriorate. Therefore, the friction resistance increases when the machine moves. When the car is started, it often leads to cold starting difficulties, and even produces burning tiles and shaft accidents. Experts explained that the wear caused by the internal engine during a cold start is equivalent to the cumulative level of 150 km. When this kind of injury accumulates to a certain extent, the car's "heart" will experience early abnormal wear and tear, even "heart failure, premature death of the year".
Therefore, experts recommend that when the lubricant is injected into the engine from the oil tank in the harsh winter season, the speed must be faster. Therefore, it is best to select a high-end synthetic lubricant with low viscosity and excellent low-temperature fluidity, which can quickly reach the interior of the engine in an instant In the corner, oil film protection is provided for components that require lubrication, which effectively reduces wear, and maintains smooth engine startup and full power output. Even at a low temperature of minus twenty degrees or thirty degrees, it provides the best protection for the engine.
Beware of freezing to prevent "cardiac obstruction"
Key point: timely replacement of antifreeze
According to experts, if the concentration of antifreeze in the engine cooling water is too low, the engine water will freeze, causing the vehicle to fail to start in the morning. Therefore, it is necessary to increase the concentration of antifreeze, and it is generally possible to maintain it at 70%. Experts told the reporter that even in the south, it is necessary to increase the concentration of antifreeze, and usually add a bottle. At this time, two bottles need to be added, generally no more than 50%. In this way, whether it is in Chengdu, or drive to the north of the ice and snow, do not have to worry about the car is not on fire. However, experts remind owners to pay attention to different brands of different models of products, do not mix, but also choose different regular brand of antifreeze according to models, if the use of poor quality antifreeze, not only will increase the water temperature, but also corrosion engine.
In addition, frost-resistant winter glass water should be replaced in environments below zero degrees Celsius in winter because it will not freeze. You should also prepare a soft rag to wipe the water attached to the windshield at any time to prevent freezing. At the same time, it is prone to fogging and frost in the winter, low visibility, and a lot of rear-end accidents. Therefore, whether or not the high-level brake lights work properly is also safe for winter driving. Protection.
Pay attention to keep warm and prevent "inflammation of the trachea"
Key point: The air conditioning system needs to be activated periodically
When the winter season is reached and the warm air is used again, the heater system will malfunction after it is stopped for a long time. Therefore, the expert reminds the friend of the owner that he or she must first try whether there is hot air, whether the fan runs abnormally or not, and the air duct. Is it smooth? Sometimes antifreeze in the warm water pipe does not flow for a long time. The condensation clogs the circulation pipe. Although it does not affect the traffic, it is very troublesome to repair. Experts reminded that with the problems, repair shops must be repaired in time, so that the car can survive the winter. If the owner does not like hot air, he must also air-condition at least once a month because the compressor oil will precipitate for a long time. If the starter activates, it can extend the service life.
In addition, if you often open hot air, we must ensure the cleanliness of the car, because at this time generally open the cycle, if you do not pay attention to the health of the car, the smell of the car will be very difficult to smell.
