The car needs to maintain oil, oil filter, air filter, brake pads, spark plugs, etc. for 20,000 kilometers. In addition to these, there will be the following items: cleaning the throttle injector, four-wheel shifting dynamic balance, replacing the air conditioner filter element, and cleaning the three-way catalytic converter. These items are generally not inspected, and the reception staff will recommend them to you when issuing a work order. They judged through experience that when this number of kilometers is reached, most cars should do these items.
During maintenance, look at the oil and oil filter. This is a must-do item. Oil in the high temperature and high pressure engine will greatly shorten the shelf life and performance. Therefore, it will not protect the engine after a long time. As for the oil filter, it filters impurities for the engine. Air filters can reduce the intake of air with impurities and increase the chance of corrosion. During the 20,000 km maintenance, you can check whether the filter is dirty.
Different spark plug materials have different lifespans. It can introduce high-voltage current into the cylinder to generate electric spark in the ignition system of gasoline engine to ignite it to produce combustible mixture. If the car is underpowered, it can be checked. In addition, in the maintenance of 20,000 kilometers, pay attention to check the thickness of the brake pads. If the wear is excessive, the brake pads need to be replaced.
Gasoline filter replacement time:
1. In order to ensure the effective protection of the gasoline filter, it is usually necessary to replace it once every 10,000-20,000 kilometers of the car;
2. Of course, we still have to make a decision based on the actual situation. When we find that the color of the filter element in the diesel filter has obviously turned black, it means that the filter element is polluted by harmful substances. Its replacement; but when we replace it, there are many places that must be paid attention to;
3. Before removing the gasoline filter, be sure to follow the steps specified by the manufacturer to release the residual pressure in the fuel system. Otherwise, it is easy to cause gasoline to overflow, and in severe cases, it will endanger personal safety; during the process of replacing the gasoline filter element, do not smoke or use open flames nearby, otherwise there will be a certain safety.
