After buying a car, many car owners began to think about some problems of car maintenance in advance, such as whether car maintenance must go to 4S shop? How often does Volkswagen maintain it? How often does a new car need maintenance? In fact, you don't have to go to 4S's auto repair shop. You can find a professional after-sales maintenance center, such as the after-sales maintenance service of SAIC Volkswagen. Let's take chassis maintenance as an example and give you some strategies for chassis maintenance.
What is the chassis?
Chassis, not a single part, is the foundation of the whole vehicle, which consists of four parts: transmission system, driving system, steering system and braking system. Engine, battery and other important equipment are directly or indirectly installed on the chassis. It can be seen that the "health" of the bottom of the car is related to the overall performance of the car, and it must not be taken lightly in maintenance.
Under what circumstances will the chassis be "injured"?
I. Obstacle scratches
The following five obstacles need to be careful. If you are not careful, the chassis will "touch porcelain"!
1. Hard foreign body
Hard foreign objects suddenly "die" on the road, which is easy to scratch the car chassis.
2. Road teeth
The convex right angle on the kerb will be hit hard once it is run over by a car.
3. Top and bottom of steep slope
Where the slope meets the top of the slope, the chassis is most likely to bump; When it reaches the bottom of the slope, the car will also produce strong vibration, which will cause the chassis parts to loosen if it is too many times.
4. Speed-limiting ridge
Passing through the speed bump at high speed will bring great impact to the tires, and then damage the automobile chassis.
5. Road traps
"Traps" such as potholes and manhole covers on the road surface not only hurt the chassis, but also make the car unfortunately "trapped".
Second, the liquid corrosion
The bottom of the car is often in close contact with liquids such as sewage and mud stains. The chemical composition inside will slowly corrode the parts on the chassis, increase the friction between parts and accelerate the loss of parts. In addition, snow melting agent and seawater will corrode the chassis. If you accidentally touch it, clean the chassis with plenty of fresh water or neutral cleaning agent as soon as possible.
How can we avoid chassis "injury" as much as possible?
In any case, be careful not to exceed the reasonable speed required by driving conditions and legal restrictions. When encountering obstacles such as buffer zones, stones, potholes, temporary steel plates for road construction, and prominent manhole covers, you must avoid them in advance or pass slowly. Always check the tire pressure of automobile tires to prevent the tire pressure from being too low and hitting the chassis during driving.
