Therefore, Jin Shu Media will make a detailed interpretation of the hot issues related to car use and car maintenance in winter, and provide some necessary help for everyone's car life in winter. Then the first issue is about the winter precautions for vehicle oil and water.
The replacement cycle of antifreeze is long, but some parallel imported cars still need attention.
When it comes to matters needing attention in winter car use, I believe that antifreeze must be the first thing that most people think of. After all, the low temperature in winter and "anti-freezing" will inevitably lead to associations, so under what circumstances do you need to replace the antifreeze?
Compared with the well-known oil replacement cycle, the replacement cycle of antifreeze is little known. First of all, we should know that antifreeze is in a relatively closed working environment, and there is basically no external pollution. At the same time, the antifreeze used in various models is also a long-term formula, so the service life is very long. For example, Toyota's first antifreeze replacement time is 8 years or 654.38+0.6 million kilometers, and Honda's replacement cycle is as long as 654.38+0 years or 200,000 kilometers. Other brands are basically the same.
According to the usage of most family cars of less than 20,000 kilometers a year, it basically means that it is difficult to put the replacement of antifreeze on the agenda. We only need to regularly check whether the liquid level in the anti-freezing auxiliary pot is normal. If cars are used in extremely cold areas such as Northeast China and Xinjiang, besides checking the liquid level, it is suggested to measure the freezing point of antifreeze in 4S shop to avoid freezing due to extreme low temperature.
When it comes to the freezing point of antifreeze, some owners of parallel imported cars in the Middle East should pay attention. We all know that the Middle East version of the car is developed and produced according to the local car environment and habits. There are always people who think that the air conditioner in the Middle East version is cooler than the air conditioner in the standard car. In fact, this is not an illusion. At the same time, the hot climate in the Middle East also makes the standards of antifreeze used in local models different from those in China.
Take the Toyota Prado with the largest number as an example. We actually measured that the freezing point of antifreeze for standard vehicles is MINUS 35 degrees or even lower, while the freezing point of Middle East vehicles is only MINUS 25 degrees, with a difference of 10 degrees. Therefore, if you want to use a car in extremely cold areas, it is recommended that the owner of the Middle East version change the antifreeze in time before winter.
Cold start protection is the key, and low viscosity of engine oil is recommended.
Compared with the almost maintenance-free characteristic of coolant, the oil change cycle is much shorter, which is basically between 5000 km- 10000 km according to different models. The choice of engine oil model has a great relationship with temperature.
For example, 0W20, 5W30 and 5W40 are all common engine oil models. From the meaning of the model, the number after W represents the kinematic viscosity of oil at high temperature, and the larger the number, the higher the viscosity. Due to the differences in working characteristics and driving habits of different engines, the kinematic viscosity is not good or bad, only suitable.
The number before "W" determines the performance of oil at low temperature. The smaller the number, the better the low-temperature fluidity of the oil, which means that the protection of the engine will be more in place during the cold start, so it can be said that the smaller the number before "W", the better. For most areas, the engine oil starting with "5W" can meet the demand of vehicles in winter, while in the cold areas in the north, it is recommended to use the engine oil starting with "0W". Of course, if you are not sensitive to the price, you'd better choose the engine oil starting with "0W". After all, there is a saying in the oil industry that "0W has no weak oil".
Of course, in winter, in addition to paying more attention to the choice of engine oil model, I believe many people also find that the speed of the vehicle is higher than that in summer when it is cold started, so is it necessary to wait until the speed is reduced before starting? The answer is no, in fact, many car companies directly wrote in the manual "No need to warm the car in the original place".
The high speed of cold start in winter is one of the measures to make the engine enter the optimal working temperature faster because the outside temperature is too low. After the vehicle is started, it can actually start running normally, and the engine coolant temperature and engine oil temperature can only reach the normal range after a short driving for several kilometers. In-situ hot car not only heats up slowly, but also affects the conversion efficiency of three-way catalytic converter.
Beware of freezing, glass water can not be ignored.
If the knowledge of antifreeze and engine oil has a certain threshold, then the common sense related to glass water can be said to be unprofessional. We all know that water will freeze below zero, so we can change the antifreeze glass water before winter. However, due to the low amount of glass water, it may be forgotten before the arrival of winter and frozen until it is needed.
If this happens, don't spray glass water forcibly, because the whole pipeline has been frozen and the water spray motor will be burned out. We just need to put the car in the underground garage, because the temperature in the underground garage is high and the glass water can thaw in a few hours. At that time, all the glass water will be sprayed out, so change the antifreeze glass water.
I believe that through the above explanation, we have thoroughly understood the matters needing attention about oil and water in winter vehicles, so we might as well continue to pay attention to the next issue of Jin Shu Media's series articles on winter vehicles. At that time, we will explain to you the precautions of other hardware in winter, and we will be there at that time.
