Since winter, the temperature began to fall, the weather is getting cool, for car, need to accept the test of low temperature again. If you want to make play the best performance of your car after autumn, must pay attention to the following 5 "don't forget".

1, do not forget to regularly check tires: car is the main material of the tire rubber. Autumn, rubber hard brittle, not only can reduce friction coefficient, leak, tire more easily also. To pay attention to check whether there is a significant trauma, scratches, and tire pressure whether standard, clear inclusions within the tire, the tread if there are any scratches, and so on and so forth must repair, avoid using hydrates tires for many times, if necessary in tire; If excessive tread wear or serious aging, cracking phenomenon, should be timely change tire. Because of the bad weather such as rain, snow in winter, very need to keep a good grip tires.

2, don't forget to often open air conditioning: after autumn, automotive air conditioning use less, because the refrigerants in air conditioning after stop working and separated refrigeration system of hydration, generate strong fluorhydric acid corrosion, corrosion of evaporator, condenser and other metal parts. Besides, after a summer of use, will remain more dust in the air conditioning duct, plus summer air humidity is bigger, can cause internal humid air duct, this breeds a lot of mold. Proposal at this time also clean the air conditioning, otherwise wait until winter for a long time can't open a window ventilated, will definitely affect driving indoor air quality, also can cause respiratory disease. Other air conditioning after downtime for a long time will cause the compressor oil seal dry adhesion, so it's best 10-15 days to start the air conditioning at a time.

3, don't forget to check the replacement of antifreeze: during the summer, many drivers used to add tap water tank instead of antifreeze, but cooler autumn weather, especially in late autumn, when the cold air, the temperature drop, is likely to affect the normal work of the automobile cooling system. Should pay attention to the antifreeze now. Antifreeze replacement cycle for two to three years or three to forty thousand kilometers, the driving normal freezing temperature is 35 degrees Celsius below zero, the boiling point at 135 degrees Celsius. Recommended to 4 s shops check the freezing point of antifreeze as soon as possible, if not up to standard will replace the antifreeze in time. Remind you before filling fangdongye need to clean them on the engine cooling system.

4, don't forget to check the oil type: winter with oil viscosity should be as small as possible, but must be determined according to the local temperature and auto level. Senior car engine oil must guide to choose, according to the manufacturer data disposal. 5 w / 40 oil than 15 w / 40 oil viscosity at low temperature are lower, compared to more easily at the instant of the cold start provide protection for the engine. If you choose the oil viscosity is too high, can make the engine cold start produce difficulties, cold start wear. Usually in Beijing winter use 10 w / 40 can satisfy the use requirement. Finally suggest drivers to use original oil, because each engine manufacturers of engine manufacturing technology, factory designated oil is selected by N times test.

5, do not forget to replace the antifreeze glass water: use the glass of water due to summer is generally not antifreeze, and some friends instead of a glass of water with water directly. But as the weather turns cold, must change for special winter antifreeze glass of water. Because cleaning is related to driving the line of sight of the windscreen and driving safety, so choose glass water don't be careless. Qualified glass water should have cleaned and antifreeze performance at the same time, anti-freezing effect bad winter water will cause the glass water freeze, serious can cause glass kettle on small water pump motor burn down. Some high-grade glass of water on the market at present with rapid melting snow and ice melting and anti glare, prevent mist, antistatic effect and so on.
