Why is a bad car rotten first, and how should we maintain it?

1. Prevent the chassis from hitting and dragging the bottom

Because the chassis is the closest part to the ground in addition to the tires, when there are big stones on the road, or when there are potholes, the chassis will be in close contact with these protrusions on the road, which is what we call the bottom of the road every day.

There is no certainty in this situation, so it is easy to damage parts located in the chassis part, such as the three-way catalytic converter casing shattering, engine oil pan cracks, transmission casing cracks or suspension system deformation, etc., which are likely to cause fatal injuries to the vehicle.

In response to this situation, the maintenance staff of the general 4S shop will recommend that you install the engine guard plate on the car or carry out the so-called "chassis armor" chassis protection for the chassis, so that even if the bottom is draggedIt will also be the guard plate that touches the ground first, without damaging important parts, which can protect the chassis to a certain extent.

2. Anti-corrosion.

Generally, new cars will be sprayed with anti-primer when they leave the factory, but after the ground baking and rain, acid rain or seawater, etc., it will accelerate the oxidation of the paint, and the parts of the chassis will be rusted and corroded, which will eventually lead to the loosening of the structure of the whole vehicle and bring potential safety hazards.

If you accidentally come into contact with an acidic liquid, rinse the chassis with plenty of fresh water or a neutral cleaning agent as soon as possible to reduce its corrosion.

These two points are more overall protection, in order to really protect the chassis, the most important thing is to protect the following three parts of the system.

Generally, the bottom is rarely noticed, after all, it is invisible, but we have to pay attention to the chassis when it is repaired.

Because the bottom of this car is the most injured, because it will be washed by all kinds of sediment, it is not easy to clean, and it will be neglected, so it must be well maintained.

Because the bottom is on the outermost, it is the most likely to be worn out, and the vehicle should be driven normally.

Because the wear and tear on the bottom of the car will be great every day, it is more likely to rot, and it should be regularly maintained to a regular 4S shop for maintenance.

Because the bottom is the most susceptible to injury, it is still necessary to go to a regular store for regular maintenance.

This is because the chassis of the car is relatively susceptible to damage.

Most of the cars don't have that high chassis, so they are most susceptible to some terrain and wear and tear.

Because the bottom of the car is the most commonly eroded by various mud and dust washes, and it will not be cleaned often, maintenance is best to be careful when washing the car.

The chassis of the car is not often noticed, but it is always exposed to the outside and can easily be injured.

Because the chassis is susceptible to damage and is susceptible to contamination during driving.

<>What does "Bad Car Rotten Bottom First" mean?

As the saying goes, it's easy to buy a car, but it's hard to keep it. Before buying a car, we can check the information on the Internet, ask the opinions of insiders, and choose the most suitable car for ourselves. But how to maintain the car after buying it has become a problem, many car novices can only drive, but will not maintain, the car will not be injured for a long time, "bad car first rotten bottom" what does it mean?

Mechanic: If you don't want to overhaul it, do it.

In fact, maintaining the car is more important than driving, many old drivers know more about the car, usually cherish the car, drive for ten years The car is still in good condition, except for the regular wear and tear, there is no major problem at all. There is an old saying in the mouth of the old driver that the bad car is rotten first, what does this mean? Listen to the mechanic, if the chassis is not properly maintained, it will not only affect the driving experience, but also be very dangerous.

A mechanic said that the role of the car's chassis is crucial, but many car owners don't know how often the chassis is cleaned. Most of the low-end cars on the market have not done chassis sealing, which is not only easy to rust, but also not good enough quality. Therefore, many old drivers buy this cheap low-end model, first of all, they have to go to the car repair shop to make a chassis seal, if you drive in a rainy area is more important, so that the chassis of the car can also be protected.

In addition to the bridge or after the chassis sealing, we should also pay attention to the car washing, in addition to cleaning the body and interior, but also to clean the chassis. Use a high-pressure water gun to simply rinse off mud and other dirt, then use some detergent. Don't drive away immediately after cleaning, we need to apply a layer of rust inhibitor so that it will not rust.

In addition to paying attention to the chassis when washing the car, you should also be careful when driving, and you must slow down in advance when passing the speed bump, if you do not slow down after the speed bump, it will not only scratch our chassis, but also hurt the shock absorption system of the car. If you don't want to overhaul your car, you can do more according to the above methods, and it is not a problem to drive for a few years.

The protection of the chassis is indeed an issue that many people will ignore. All kinds of vehicles will be treated with anti-rust chassis when they leave the factory. Car manufacturers generally have a 10-year rust protection guarantee through electrophoresis and spraying PVC, but this guarantee is given without damage to the chassis.

As the car speeds on the road, the sand and gravel will splash under the rolling wheels, constantly hitting the chassis of the vehicle, and the electrophoresis and PVC layers on the chassis can be easily destroyed when it leaves the factory, leaving the metal completely exposed. In addition, the baking of high temperature in summer, the erosion of rainwater, the snow on the road in winter and the corrosion of the industrial salt snow remover widely used in China, as well as the possible influence of acid rain in industrial cities, moisture and salt in the atmosphere, are all factors that cause damage to the chassis metal, which leads to rust of the chassis, deformation and noise in severe cases. Chassis deformation is not easy to detect, but it can affect driving safety.

The data shows that many traffic accidents are caused by the deformation of the chassis.

The protection of the chassis is so important, but perhaps because of the inconspicuous position, it is not as valued as the beauty of the paint. Many cars look bright on the outside, but when you look at the bottom of the car, the chassis has long been rusted. So from this point alone, it can indeed be seen whether the owner really knows how to love the car.

Knowing how to protect the chassis, the vehicle will not age in advance, and the safety and driving comfort will be guaranteed. The chassis is well maintained, and the car really should be worth a little more. And if it's a "bad bottom car", you have to be careful about whether the car has hidden dangers in other aspects.

Specific to the protection measures, it is recommended that according to the structural characteristics of the chassis of different brands of vehicles, as well as its particularity in terms of protective treatment, different chassis armor products can be matched to increase the rust-proof, impact-proof, anti-fouling and sound insulation of the chassis.

Suggestions: 1 Pay attention to road conditions, slow down carefully in uneven places, do not overload, and wash and maintain the car frequently.

2. Go to the maintenance station to do the chassis inspection and maintenance in a timely manner.

Actually, what I said is equivalent to not saying it. The most important thing is that you can treat your car as a beloved woman, and it will be no problem to take care of it carefully.

1. Chassis armor is about 300.

Second, the installation of protective steel plates, car decoration stores and 4S are sold for about 200.

Third, the floor glue is generally in the range of 200-400.

Fourth, pay more attention to driving by yourself and be careful of collisions!

Pay attention to tire maintenance, otherwise it is easy to break.

<> "Everyone knows that it will be able to run 600,000 kilometers in almost 15 years, and the car will run almost 600,000 kilometers before it is time to be scrapped. Even if it does not run 600,000 kilometers, after ten years, the annual review may be changed to twice a year. If the annual review is changed to four times a year after a few years, it will be really too troublesome to drive.

In the past, when there was no car, everyone thought it would be good to have a car. If you want to go, you will imitate defeat and go to a road trip. But when you actually drive yourself, you will find that the car is a very troublesome thing.

If you don't pay attention, the car will lose its life if it will be damaged. Even if you don't expect to drive a car for more than ten or twenty years, but I don't want to drop the chain every time I drive, so an old driver said, in fact, there is a way, when you just buy a new car, don't drive it directly. Install a chassis armor first, which can ensure that you will not have problems with the chassis for ten years, and the cost is also very cheap, about 1200 yuan.

We know that the chassis of a car, that is, the bottom of the car, determines the passing performance of the car. The chassis is important. More important than the internal transmission of the engine.

The chassis is closest to the ground and supports the entire body. As the saying goes, a bad car starts with a bad bottom, and if there is no chassis armor, it will come into contact with all the dirt and obstacles on the ground after a long time.

Therefore, after the car is bought, don't be excited to wander around, you can spray the anti-collision and anti-rust primer once, but this is generally very thin, and it only plays a role in additional protection; It is important to make another chassis armor so that the chassis of the car can be protected from rain, dirt, dust, acids and pollutants in all directions.

After installing the chassis armor, although it cannot resist all external aggressions, it is like the old driver often says, the speed of the car is more than 120, and any anti-collision measures are useless! But chassis armor can easily cope with all kinds of small problems, at least for ten years, your car will not have problems with the chassis first.
