Which expert says which car maintenance is wrong and can be harmful to the car.

The sealing glaze is wrong, hurting the car paint.

Hazards of not maintaining a car on time:

1. Appearance: From the appearance, the main thing is that the paint of the car is susceptible to damage, especially in the summer, when the weather is too hot, the ultraviolet disadvantage line will corrode the paint of the car.

2. Air filter: After the maintenance period has not been replaced, the air filter is not replaced, because of the poor filtration effect, the difficulty of suction leads to insufficient mixing of gasoline and air, which is easy to produce carbon deposition and power decline.

3. Engine oil and filter: Once the oil container is opened, there is a possibility of oxidation.

4. Long-term non-maintenance can easily lead to carbon deposition in parts: carbon deposition often occurs in automobile engines, which not only have the characteristics of oil absorption, but also convert incomplete combustion gasoline into carbon deposition, resulting in serious damage to the engine and causing the engine to fail to work normally. 5. Oil deterioration:

Any good quality engine oil will change in the process of renting potatoes. After a certain mileage, performance decreases and carbon deposits increase, which can cause problems for the engine.

1. Automobile paint is susceptible to high damage, especially in summer, when the weather is hot, ultraviolet rays will also corrode automobile paint, in this case, the automobile paint is easy to become old, and the car body will crack when it is more serious.

2. The use of tires for a long time will lead to insufficient tire pressure, which will not only cost fuel, but also damage the tread after a long time. In addition, if you do not clean up the stones and other debris in the pattern in time, the wear and tear of the tires will be very serious, and it will not take long to cause the tires to be scrapped.

3. Usually the replacement cycle of the air filter is 10,000 to 10,000 kilometers, and if it is not maintained and replaced for a long time, the air filter will also lose its sail and be filtered.

If the car is not maintained in time, at the beginning, the car will just have various skillful lead problems, such as increased fuel consumption, shaking, etc. Over time, problems accumulate day by day, and eventually the vehicle is completely scrapped and unable to drive. For example:

1. If the air filter is not replaced in time, a lot of dirt will accumulate inside, which will block the engine and cause ignition failure. And dirty air can enter the engine and cause engine damage.

2. If the debris on the tire is not cleaned up, the tire will be worn out for a long time, and the tire will burst after a long time.

3. If the air conditioning filter is not changed for a long time, it will cause the air in the car to be polluted or even smelly, which will affect the health of passengers in the car.

4. If the oil is not replaced for a long time, it will deteriorate, and then it will corrode and damage the engine.

Therefore, we must maintain filial piety on time and develop good habits.

1.Car paint. Car paint is susceptible, especially in the hot summer months, and UV rays can also corrode car paints.

In this case, the car is prone to getting old. When the condition is more serious, the car body is easy to cause cracks, and it will also make the car not very good outside. If you want to deal with this matter, you have to start at the parking place, and the car is easy to be exposed to the sun when parking outside, so it is best to cover it with a car coat and find an underground parking lot!

2.Air filter.

Clean gasoline is also mixed with pure air to maximize fuel economy. Usually the replacement cycle of the air filter is 10,000 to 10,000 kilometers, if the replacement range of the air filter is exceeded, the air filter will also lose the filtered air into the engine impurities, the car starts the internal piston, intake and exhaust valves, piston rings and cylinder protection and then loses its effect.

3. Tires. If the car is not used for a long time, the tire will also accelerate the aging, and in severe cases, it will lead to tire loss and scrap. The longer the drive is stopped, the more difficult it is to recover the deformed parts.

Before the vehicle is parked, you can have enough pressure on the tires, and a little higher is no problem, so that the tires can withstand a certain amount of pressure.

4. Oil. Fluids generally include: engine oil, brake fluid, steering power, antifreeze, etc.; Although the car has not been moved for a long time, and there is no new increase in kilometers, the oil has a shelf life, especially the engine oil.

If the vehicle is parked for a long time, the oxidation of the engine oil will be more serious than usual, and the lubrication effect of the oxidized oil will become worse, not to mention the effect of protecting the engine. Therefore, the car will not be used for a long time, and the oil needs to be changed regularly.

5.Long-term non-maintenance will cause carbon deposits on the parts.

There are often carbon deposits in the car engine, carbon deposits not only have the characteristics of oil absorption, but also make the incomplete combustion of gasoline into carbon deposits, and if the car is not maintained for a long time, it will also damage the engine more seriously, so that the engine can not work normally, and it is also hoped that the owner can do car maintenance or testing every once in a while, so as to ensure that their cars can be used normally!

6.Over time, the oil will deteriorate.

Regardless of the type of high-quality oil, the oil quality changes during the use process. After a certain mileage, the performance will be reduced, and the carbon deposit will also have some problems with the engine. To prevent accidents, it is also necessary to combine with good quality lubrication products to protect the oil tank, ** lubrication system maintenance kit can deal with too much sludge, the power will decrease, and some problems caused by too much fuel consumption, wear reduction and noise reduction will automatically repair wear and tear to the surface, and the power will increase the life!

Replace or add antifreeze promptly.

In winter, the outdoor temperature is very low, and if the vehicle wants to operate normally, it must have normal antifreeze, otherwise the water tank will be frozen and cannot circulate normally, and the vehicle will break down. Antifreeze should be between max and mix, and if it is missing, it should be replenished in time.

Change the glass of water in advance.

In winter, when washing the front windshield with glass water, be sure to use glass water with good antifreeze effect, so that it will not freeze when washing the glass. Otherwise, it will damage the wipers and affect the driver's vision.

Check that the oil is sufficient.

In winter, the car runs normally, and the oil plays a great role, so be sure to carefully check whether the oil scale is within the normal range before winter comes. Let's see if it's time to change the oil of your car? The oil can be changed according to the kilometers on the maintenance manual.

Put up the wipers.

If it snows heavily and the car is covered with thick snow, when cleaning the snow on the front windshield, be careful not to scratch the glass with sharp weapons, especially the wipers, and do not open them before thawing, otherwise the wipers will be damaged, and it is best to erect the wipers.

Warm up the car properly. When driving in winter, do not heat up the car for too long, it is recommended to let the car walk slowly for 3 minutes after half a minute of hot car before turning on the air conditioner and driving at high speed, do not slam the accelerator, because the viscosity of the engine oil increases in winter and the circulation slows down.

Maintain normal tire pressure.

1. The appearance is darkened, and the paint is corroded or even cracked. When a car is parked for a long time, the surface of the body is susceptible to the external environment, such as wind, sun and rain, and even the car parked indoors will suffer from the corrosion of harmful substances such as dust and impurities. Combined with a lack of maintenance, the surface of the car will lose its luster, and the car will appear to deteriorate, corrode and crack the paint.

2. The engine breaks down quickly. Cars need to be serviced regularly, and if they are not serviced for a long time, especially if they do not change the oil and filters regularly. With the increase of acids, gums and iron filings in the oil, the color of the oil will gradually turn black and the viscosity will gradually decrease, which will clog the oil filtration system, cause poor engine lubrication, and accelerate engine wear.

However, the air filter will gradually lose its filtration function due to the lack of fresh air inhaled to maintain normal operation, coupled with the hazard of dust and substances, and hinder the operation of the engine.

3. Brake fluid failure. Brake fluid has a lot to do with driving safety. Brake fluid contains ethylene glycol, ethylene glycol is a substance that is very taboo to contact with water, but long-term parked cars are not maintained frequently, and it is easy to inhale moisture in the air, resulting in brake fluid can not play the role of brake.

When braking suddenly, there will be a situation where the car cannot be braked, threatening the personal safety of the owner.

Car maintenance should be done within the specified range of the number of kilometers used, if the amount of use does not exceed the regulations, it is okay, and the operation of more kilometers or with the front to sell maintenance to avoid excessive use of training caused by serious wear and damage to components.

Accelerates the wear and tear of the vehicle, causing the vehicle to malfunction.

Reduce the service life of the car.

<> "What are the common misunderstandings in car maintenance.

Car owners are absolutely sparing no effort in the maintenance of their cars, not only because it brings us convenience and comfort in travel. Of course, it is good to pay attention to the maintenance of your car, but there are often many car owners who over-maintain it during the maintenance process. There are also some car owners who do not know much about the maintenance, which causes unaware incorrect maintenance.

First of all, in addition to gasoline and water, there are many parts of the liquid in the car that are various engine oil additives. Often, car owners do not know much about this kind of additives, which often leads to the phenomenon of adding the wrong additives. At present, there are many fuel and oil additives on the market that claim to enhance power and reduce fuel consumption, but not only do not boast the functions advertised, but will aggravate the wear and tear of the engine.

We should be cautious about the selection of various additives, after all, the car is a very fine product, and there are corresponding technical index requirements for fuel, lubricating oil, brake fluid and coolant. Car owners should choose regular products designated or approved by the automobile manufacturer when adding or replacing them.

Again, car washes. For car owners, they not only pay attention to whether its internal functions are normal, but also consider whether its appearance is neat. Bathing your car often is something that car owners often do.

However, car bathing too diligently, just like people taking baths too often, will lead to dryness and aging, resulting in premature aging of car paint. The mud and sand entrained by the rag used for car washing scratched the car paint, which is also one of the reasons. In the survey, it was found that about half of female car owners are prone to overmaintenance, especially the number of car washes, and they average more than twice a week.

If you want to keep your car clean and tidy and don't want to hurt the car, the owner can put a feather duster in the trunk and use it to solve a little dust, which can greatly reduce the number of car washes. Moreover, feather dusters are not easy to accumulate sediment, and as long as you pay a little attention when dusting, you can avoid scratching the paint.

Finally, although winter is already fading away, there are occasional times when the temperature is not high when you wake up in the morning. Car owners are used to hot cars when they start their cars. It is said that nearly three-thirds of car owners are willing to get up early in the morning and idle for a long time in place to warm up the car, thinking that the car is like a person, and it is more energetic to exercise after warming up.

In fact, long-term idling in place not only has a limited effect, but also accelerates the aging of components such as three-way catalytic devices.

In this regard, many experts have said that the correct way to warm up the car should be after the car starts, as long as the oil lamp is turned off, you can drive slowly. However, you can't press the accelerator too much at this time, and you can only speed up when the water temperature reaches normal temperature.

Of course, there are many things to do to maintain a car, more than the above. Proper maintenance of the car can not only prolong its service life, but also increase the safety of your life.

If the car is not maintained on time, the probability of problems will be much higher, and the later maintenance costs will be more than the car maintained on time, and the overhaul period will be advanced, and there will be more minor problems when driving. Safety, driving performance, etc. will be compromised.

Hello, the maintenance operation of the car is very necessary, regular maintenance of the vehicle, can reduce the failure rate of the engine, chassis, electrical appliances and other components, and the maintenance cost is not very high. If the engine or chassis components fail due to unscheduled maintenance, the repair costs incurred will be more than ten times or even dozens of times the maintenance costs.

If the warranty period is not out, the manufacturer will no longer guarantee after maintenance in an external factory. Including any repairs and modifications made in other factories. General decorations, such as wrapping, will not affect.

If the warranty period is out, you can do maintenance in the factory. But I hope you choose a repair shop carefully, because there are many doorways, and most of the car owners are laymen. There are also some models with low penetration rate and special structure, which should be cautious when doing maintenance and repair in other factories.

Attention should also be paid to the quality and matching of various fluids, parts.

Potential problems if not maintained in a timely manner:

The performance of the car is abnormal and the braking ability is reduced;

The internal parts of the engine of the car are damaged, and the engine noise is loud during driving;

The braking system will be abnormal, and the car is prone to deviation during driving, which will affect driving safety;

In response to your problem, it is necessary to do it regularly given that the maintenance of the car will only prolong the life of the car and ensure personal safety.
