First, car owners need to focus on inspecting several parts of the vehicle after a long drive, first of all, the wheels. If you find obvious scars or abrasions, you should replace the spare tire in time and go to a 4S store for further examination. In addition, long-term bumps will affect the positioning of the tires, and the vehicle will deviate or jump, so you also need to go to the 4S store for inspection.

Second, the second is the air filter in the engine compartment, if the road section through the dust, the air filter may absorb too much dust, and then cause wear and tear to the components in the engine or cause the engine to be poor air intake, affecting the power. Therefore, the air filter needs to be removed to check the cleanliness.

3. Exterior and paint inspection, including body surface and all components. Long-distance driving will inevitably hit small stones bouncing off the road, causing damage to the paint surface of the car, so it is necessary to carefully observe whether the paint surface is scratched or whether other parts are damaged, and wash and clean. The benefits of inspecting a vehicle's exterior and paint finish are not only aesthetically pleasing, but also avoid problems caused by damaged components.

It is important to inspect your vehicle after a long drive to help identify and resolve issues and ensure safe driving and proper vehicle operation.

Fourth, the brake system inspection. On the Internet, I often hear some netizens report that after the car is used for a period of time, there will be obvious grooves on the brake disc. My own car is ok and I don't have this problem yet.

Speaking of which, this may be due to the fact that when the vehicle is driving on a gravel road, some fine gravel is stuck between the brake disc and the fender, constantly rubbing the surface of the brake disc, so there are grooves. And when this happens, Che Xiaoqi may make a sound of "dang, dang" when walking, and in some cases will hear a scream when braking.

In this case, we can visually inspect the surface of the brake disc through the aluminum alloy steel rim of the tire, and if the surface of the brake disc is smooth, it indicates that it is normal.

Fifth, engine oil inspection, generally speaking, the lack of engine oil after long-distance driving is a more common phenomenon, if you forget the previous number of oil added, do not blindly add new oil, because the mixing of different grades of oil may cause adverse consequences. Experts say that the correct way is to clarify the original oil label and then choose the same label to add. If your service is almost up, simply clean the original oil and add a new one.

One: Tire inspection.

Some cars experience visible scarring, excessive wear or "trauma" to the wheels after long drives. At this time, according to the specific situation, you can choose to change the spare tire and go to the 4S store for further inspection as soon as possible. In addition, after a long period of bumps, the positioning of the tires may fail.

The most striking feature of this rock mass is that the vehicle will deviate and jump. If this happens, you need to go to the 4S store for inspection. Skin.

2. Internal component inspection.

One part that needs to be checked in the engine compartment after a long drive is the "air filter". If you drive with more dust than in the city, the air filter may have absorbed too much dust during this time, and if dust enters the engine, it will cause wear and tear on the engine parts; It will cause poor air intake of the engine and a decrease in power. Therefore, it is necessary to remove the air filter for inspection.
