Don't overload the battery.
The temperature in Guangdong is usually very high. If you don't drive to the north in winter, you generally don't need to change the low-temperature engine oil and antifreeze, but the battery needs special care. "Before coming every winter, it is best to remove the car battery and charge it for half a day." Fan introduced that automobile batteries are most afraid of low temperature, and the battery capacity in low temperature environment is much lower than that at room temperature.
Therefore, before the arrival of the cold season, the electrolyte of the battery should be replenished, and the terminals of the battery should be cleaned and coated with special grease for protection, so as to ensure reliable starting and prolong the life of the battery.
There are more and more electric devices in cars, so car owners should try not to overload their batteries when using these electric devices. Take electric windows and skylights for example, the owner should complete their lifting and closing before the engine is turned off, because if the engine is turned off, it will stop generating electricity. At this time, lifting the window will increase the load of the battery and easily cause battery damage.
The same is true for headlights. If it is not necessary to turn off the lights, you should turn off the headlights first and then turn off the lights. When starting the car at night, you should start the headlights first and then turn them on to minimize the damage to the battery.
Keep the thermostat working properly
In addition, car owners should also pay attention to the thermostat. Fan said that the thermostat is used to automatically control the normal water temperature of the engine, which can quickly heat up the engine when it is started at low temperature and reduce cylinder wear. In some cars, when the water temperature is high in summer, the repair union removes the thermostat. Although the problem can be solved in summer, if the thermostat is removed in winter, the engine start-up time will be extended by 4 to 5 times and the cylinder wear will increase by 5 to 6 times. Therefore, it is incorrect to disassemble the thermostat at will.
In addition, in summer, many drivers often use pure water or tap water with detergent as glass cleaning liquid.
But it is dangerous to use tap water as glass cleaning liquid in winter. If the owner goes to the north, substitutes such as pure water and tap water are easy to freeze in low temperature weather, and it is also easy to damage the container. If the car mainly drives to the north in winter, the original substitutes such as pure water must be released and replaced with glass cleaning liquid that is not afraid of freezing.
