【Car owner’s home car knowledge】The Spring Festival is coming soon, and many people working outside are starting to go home one after another. Some take planes, some take trains, and some drive home. To say that it is the most convenient, it has to be self-driving. You don’t have to suffer from waiting or fighting for tickets. However, for the car owner who has a long journey, driving home may be too tiring. So, they usually put their cars in Shenzhen. So, what should you pay attention to and how to maintain this kind of vehicle that will be kept for a long time?
As we all know, once a car is stopped for a period of time, many problems may occur; such as oxidation of engine oil, aging of rubber, battery defects, tire deformation, etc. Therefore, how to solve car problems is the first priority for car owners before returning home.
1. Before going home
1. Do a good job in car cleaning
Before parking the car, cleaning is very important. The entire car should be cleaned and tidied without leaving any mud stains. In addition, the tire pressure should be adjusted to the upper limit, the fuel tank should be filled with oil, and the entire vehicle circuit must be turned off; before the car is stopped, the battery should be fully charged and unplugged.
2. Choose a suitable parking spot
If possible, it is best to park the vehicle in an underground garage. If it is parked in an open parking lot, the car must be covered with a car cover. Choose a thick, multi-layer car cover as much as possible to effectively reduce the impact of sunlight or rain on the paint surface. Remember not to park your vehicle directly in front of a shop or in a ground parking space in a community for cheap, to avoid unnecessary damage to your vehicle.
3. Ask someone to start it every few days.
If the car owner has friends who are local or not home, they can ask the friend to start the car every few days, even for a few minutes, so that the battery can be charged.
4. Anti-rodent
When a car is parked, there are two things to avoid: first, moisture, and second, rats. Moisture will not only corrode metal parts, but also damage electrical components, which is fatal for cars with a high degree of automation. Many people may not take rat damage seriously, but its destructive power is often beyond people's imagination. Wires, tires, interior parts will all become food in their mouths. Therefore, clean the cab carefully and do not use a too wet cloth when wiping to avoid excessive moisture.
The best way is to use a vacuum cleaner with small things like cotton swabs and sponge strips to remove all the dirt. In addition, 4S store experts also suggested that the battery can be removed because they are afraid that mice will bite the wires and cause a short circuit, which may cause a fire. If possible, rat poison can also be placed in the car to reduce risk factors.
2. After return
1. Check the battery and charge it
Lead-acid batteries are generally used in cars. Its characteristic is that it will generate self-discharge once the car is stopped. Under normal conditions, self-discharge of the battery can reduce the capacity by more than 1% every day and night. What is particularly serious is that after the battery self-discharges for a long time, sulfides are produced on the surface of the plates, which affects the recharging effect of the battery and may eventually lead to premature scrapping of the battery.
Therefore, after coming back, if you feel that the battery charge is not enough, please turn off all electrical equipment first and let the engine rotate at 2000 rpm for about 5 minutes to charge the battery.
2. Start up within 5 seconds
If your car has not been used for a long time, it may not be able to start again when you start it again, and it may take two or three times. But it should be noted that each start-up should not take more than 5 seconds. That is to say, if you have not driven the car for more than a week, you must start it carefully and use other parts carefully when you use it again.
3. Ventilate when starting for the first time
If the engine starts successfully, check whether various functions are normal and ventilate the vehicle for several minutes.
