How to do a good job of vehicle maintenance when winter comes?
The focus of vehicle maintenance is to inspect and maintain the power batteries, heating devices and engines of new energy vehicles, water tanks and antifreeze of diesel vehicles, and to inspect and maintain the brakes, steering, lights, tires and on-board fire extinguishers of all vehicles. At the same time, strictly implement the safety inspection system for operating vehicles to ensure that vehicles are in good safety and technical condition at any time.
Through the maintenance of vehicles in winter, the ability of vehicles to cope with bad weather is further improved, and the normal operation of buses in winter is ensured.
Before winter comes, we should pay attention to some problems in car maintenance. These problems are not new topics, but should be paid attention to every year, always starting from scratch.
1. Tire pressure problem. It is easy to understand why it expands when heated and contracts when cooled. Temperature has a great influence on gas. As summer gets farther and farther and winter gets closer, it is necessary to check the insufficient tire pressure.
2. battery problem. It's very cold in winter, so it takes a lot of power to start the engine. The old battery may be too tired, and it will mute when starting the car. If it is too difficult to start the car engine, you must consider replacing the battery.
3. Glass water and wiper problems. Good quality and low price, but you must choose good quality. There is frost in autumn and winter, so it feels different to use high-quality glass water and wipers.
4. Anti-freezing problem. Replacing antifreeze should also choose genuine products. ① Anti-freezing, ② Anti-boiling and ③ Anti-corrosion are the keys, and the regulations must be observed. Never use inferior products cheaply. Before replacing antifreeze when necessary, clean the inside of the cooling system, go to a regular garage and have a special cleaning agent, and do it according to the regular method. When the cooling system is seriously corroded, the discharged old antifreeze will become dirty and need to be replaced by professional equipment. After the antifreeze is discharged, consider adding another bottle of water tank protector to protect the cooling system and prevent leakage.
5. Oil problem. Oil should also be used in winter and summer, and some cars are very demanding. Go to a regular repair shop and let the master talk.
6. Maintenance of air conditioning system. Automobile air conditioning system should be maintained at least twice a year, once in Zhixia in spring and once in autumn and winter, especially in autumn and winter. After the hot and humid weather in summer, the air conditioning system is likely to be dirty, there are many molds in the cab, and the air may be dirty. Warm wind is turned on in winter, and the windows are sealed. It is rare to open the window to breathe the natural wind like summer. Open warm air to increase the activity of bacteria. Passengers' resistance will be worse in winter, so air conditioning system maintenance and indoor disinfection are needed before winter.
