Some maintenance projects sound professional, but in fact they can be done by themselves and can be easily done with a wrench.
Replace spark plug
1 What I want to say is the spark plug on the tall one. Liang Zheng said in his paper "The Structure, Use and Maintenance of Spark Plug" published in Vocational magazine that only when the engine is in a cold state can the spark plug be disassembled with a socket wrench.
In addition to requiring fewer tools, the replacement process is relatively simple. After opening the engine compartment, remove the plastic cover on the engine first. After the cover was removed, I found the ignition coil, which was arranged in a row and looked a bit like a cover. Several things are arranged together with a line at the end.
After unscrewing the above screws with a socket wrench, you can remove the coil and see the spark plug. Then use a suitable socket wrench to remove the spark plug, which is not much different from ordinary screwing. When installing the spark plug, apply a thin layer of silicone grease to the ceramic part, just like applying ointment or wind oil essence, and then tighten the spark plug with a socket wrench. Yes, it's finished.
Air exchange filter element
Second, let's talk about the air filter element of the engine, which is also very simple to change. The air filter element and the air inlet are the air intake system of the engine, which is equivalent to the human respiratory system and can also be understood as the mask of the car.
So, if you want to find the location of the air filter, just pay attention to which plastic box in the engine compartment is behind a thick intake pipe.
After finding this filter box, open the buckle on it, or unscrew the screw with a screwdriver, and you can take out the filter inside, take it out and put it in. All right. Yes, all right. It is also very similar to changing the filter element of the air purifier at home.
Replace air conditioning filter element.
The third is to change the air conditioning filter. It is not as complicated as we thought to replace the air conditioning filter element by itself, mainly to find its own position. Different models have different positioning. The common position is under the windshield of the co-pilot side in the engine compartment, or behind the glove box of the co-pilot.
The engine compartment is easy to change, similar to an air cleaner. You can take out the filter element by opening the box and buckle, or removing the screws. The back of the glove box is a little troublesome. You need to remove the glove box first.
These two kinds of filter elements are changed by hand, and the cost is basically tens of dollars. You have to buy very good raw materials, and hundreds of dollars are also top materials.
Change wiper
Finally, talk about changing the wiper. It's so simple that you don't even need tools. When replacing the wiper, just pull out the swing arm of the wiper, and then find the buckle at the joint between the swing arm and the wiper, and then you can remove and replace the wiper.
It should be noted that when the wiper arm cannot be pulled, do not pull it hard. Some cars are manual, but others are electric, so you need to set the wiper to the maintenance position in the car. Before replacing it, please check the opening mode of the wiper rocker arm of your car.
