01/ Timely replacement of glass water
Auto glass water is generally divided into summer glass water and winter glass water, auto glass water is a combination of multiple surface plane active agent and additives, with anti-static properties, play a lubricating effect, reduce the friction between the wiper and the glass, to prevent scratches.
Winter glass water is based on antifreeze performance as the benchmark for selection, you should choose the glass water whose freezing point is more than 10 ℃ below the local minimum temperature. Otherwise, it will cause problems such as frozen glass water and water sprayer pump failure. So the arrival of winter time to their cars in time for the winter special glass water, remember to empty the glass water pot in the summer glass water oh.
02/ Timely addition and replacement of antifreeze
Winter temperature in the north will reach below zero, if you add ordinary water inside the car tank, it is easy to freeze, not conducive to the start of the car is also prone to cause damage to the tank and the engine, so be sure to add the antifreeze suitable for their own local area temperature. So don’t forget to check the antifreeze, if the freezing point does not reach the lowest temperature of the local air temperature, please replace it in time.
How to choose antifreeze?
Common antifreeze freezing point in the market has -15 ℃, -25 ℃, -30 ℃, -45 ℃ and other specifications, the lower the freezing point of antifreeze, the stronger the antifreeze performance, the general use of antifreeze can be based on the local minimum temperature is lower than 10 degrees Celsius to choose antifreeze, for example: in Qingdao area antifreeze selection -25C the majority of.
03/ Timely oil change
Motor oil is a lubricant belonging to the engine, generally divided into summer oil, four-season oil and winter oil, in the winter we must change the right oil, the normal flow of oil is to ensure that the engine is an important part of the normal work of the engine, but the realization of these functions is mainly the viscosity of the engine oil and mobility related to the viscosity of the engine oil will also be related to the changes in temperature, so sometimes in the winter, every morning to start the So, sometimes in winter, every morning start, it will be more laborious, is because the viscosity is relatively high, poor fluidity of the reason, so the winter to change the viscosity of low, good fluidity of the engine oil, and these are also with the engine oil labeling has a certain relationship.
Here are the parameters of the grade.
5W represents the external low temperature up to -30℃
10W represents the external temperature up to -25C
15W represents the external temperature up to -20℃
20W represents the external temperature up to -15℃.
The smaller the number, the better the low-temperature fluidity of the oil. The later number tests the index of the oil’s high-temperature resistance, and the larger the value, the better the oil’s protection performance at high temperatures.
