What should I pay attention to in winter maintenance of vehicles?
cooling system
Whether the water tank, water pump, belt, water pipe, make-up water tank and other parts work normally, if there is any damage or failure, it is best to repair or replace them in time. Otherwise, a bucket of antifreeze may be wasted on a small water pipe. Especially in summer, when the water temperature of some cars is high, the repair union removes the thermostat. Although the problem can be solved in summer, it will be reversed in winter. In a word, this is not a good way to completely solve the problem.
A warm slope
Warm air that has been left for a summer often fails. It is best to try whether there is hot air, whether the fan is running abnormally and whether the air duct is unobstructed. Sometimes the problem is that the antifreeze in the warm air pipe does not flow for a long time, and the condensation blocks the circulation pipe. Although it does not affect driving, it is very troublesome to maintain.
antifreezing fluid
Check whether the liquid is in short supply or deteriorated, and replenish or replace it in time if necessary. Antifreeze seems trivial, but it has a great influence on the car, from blocking the pipeline to corroding the cylinder block. Therefore, choose antifreeze carefully. First, don't mix. Second, don't use fake and shoddy products. In addition, generally speaking, antifreeze should be changed once every two years, and it is best to wash the cooling system with clear water before replacement.
motor oil
Check the label for low temperature, missing or deterioration. In winter, the oil of cold car is too thick, which will affect the start-up and increase the wear of parts. At the same time, too thin oil will reduce lubrication and sealing performance. Choose high-quality compound oil suitable for winter. If it is at or near the specified oil change time, it is best to change it before the weather gets cold.
basis
It seems that it has nothing to do with the low temperature in winter. In fact, the gear oil in the differential and transmission is very thick, and its temperature rise * mechanical movement. When the temperature is very low in winter, the improperly labeled gear oil will solidify, which may damage the gear or oil seal. In addition to checking whether the label of gear oil is suitable for the local temperature, it is also a good habit to drive at a low speed for a while after starting in winter morning.
brake fluid
Brake oil will absorb the moisture in the air when it is used. After a long time of use, the moisture in the oil will be more and more.
It is rare to freeze in severe cold, but once it happens, the consequences are very serious. Please refer to the manufacturer's requirements for regular maintenance.
Car repair is a dirty and tiring job. The severe winter on March 9 will make the maintenance work more difficult, which will inevitably affect the maintenance quality more or less. I suggest that you do a good job of inspection and maintenance before the weather gets cold and spend this winter safely.
Most of the above inspections can be done by yourself, and then you can decide whether to go to the repair shop for comprehensive maintenance. Interested car owners may wish to have a try.
