It is wrong to replace the spark plug if it is not broken. When the spark plug reaches the replacement cycle, it needs to be replaced regardless of whether the spark plug is damaged or not. The replacement cycle of spark plugs of different materials will be different. If it is a spark plug made of platinum, the replacement cycle is about 40,000 kilometers. .
After the spark plug has been used for a long time, the wear of the spark plug will be more serious, and it will gradually age. The specific impact of spark plug aging on vehicle performance:
1. The power of the vehicle will be reduced. When the accelerator pedal is stepped on, the speed of the vehicle will not increase significantly, and there will be a more obvious sense of powerlessness;
2. The vehicle will vibrate during driving. The jitter is relatively slight at the beginning, and then the jitter will become more serious.
When the vehicle has the above three conditions, it is likely that the spark plug is aging, and the owner needs to replace the new spark plug as soon as possible, so as not to affect the use of the vehicle.
The owner of the spark plug can do it manually, and the difficulty will not be great. The specific steps are as follows:
1. Open the hood of the vehicle, and then find the spark plug in the engine compartment. There will be a lot of wires on the spark plug. This wire is a high-voltage branch line, which needs to be unplugged;
2. If there are sundries next to the spark plug, they need to be cleaned up first, so as to better prevent the sundries from entering the spark plug hole;
3. After cleaning up the debris, you can directly unplug the spark plug. After unplugging, you can replace it with a new spark plug, and finally install the high-voltage branch line, thus completing the replacement of the spark plug.
