Cars are more than 654.38+ 10,000 kilometers. What parts must be replaced if you don't change cars?

I have been driving a taxi for 8 years and Didi for 4 years, and I am currently engaged in the used car industry. As an old driver who specializes in dealing with used cars, I can tell you what parts to replace for a 65438+ 10,000-kilometer car. It is realistic, not theoretical.

There are many things that need to be replaced, including instructions and maintenance manuals, such as timing chain, spark plug, brake oil, coolant and so on.

Many things are maintenance manuals, which say that they must be replaced within 65,438+10,000 kilometers. If you go to the garage, the mechanic will definitely tell you that there are many things that need to be replaced.

But what really needs to be changed and what doesn't? I believe everyone is very confused.

I have a comrade-in-arms who has been driving for two years and walked 60 thousand kilometers. He will call me every two months and ask me what his car needs to be changed.

The first is the tire.

Under normal circumstances, a car's tires can rarely run more than 65438+ million kilometers. Go to the tire shop, and the boss will usually tell you that it is 60,000 to 70,000 kilometers.

But in fact, ordinary tires should be able to run about 65438+ 10,000 kilometers. I have seen/kloc-more than 0/00000, but that is a minority, usually around 65438+ 10000 km.

It also depends on your driving style and road conditions. If you drive in poor road conditions, it will lead to inaccurate four-wheel positioning and direction deviation, and it is easy to eat tires unilaterally. In this case, 40,000 to 50,000 kilometers of tires may be scrapped.

If your driving style is sudden start and stop, it is also very useless. Under normal circumstances, it is about 65438+ million kilometers. You must pay attention to your tires. If the tread is too shallow, replace it.

The second is transmission oil.

We change the oil frequently, usually around 10000 km, but the gearbox oil is forgotten by many people. Especially for private car owners, if the gearbox is not broken, he may not even know to change the gearbox oil.

The current gearbox is divided into dual clutch, cvt and at.

Theoretically, the dual clutch and CT should be replaced around 60,000 km, and when the At is less than 65,438 438+ 10/00,000 km.

But in fact, many of my friends changed their cars by driving cv and T gearboxes for about 654.38+10,000 kilometers, and the cars were all right.

At drivers, I have met many friends who have been driving for more than ten years, running 200,000 to 300,000 kilometers, but they have never changed the gearbox oil, but there is no problem.

However, because the gearbox is expensive, it costs thousands to tens of thousands at a time. The price is very expensive. It is recommended that you change the transmission oil about 65438+ 10,000 kilometers.

After all, gearbox oil is not expensive. If you change to gravity, the online e-commerce platform can be bought, and there will be a replacement location in your city. Even the oil belt replacement is only around 300 yuan.

If your car is a manual transmission, theoretically it needs to be replaced around 65438+100000 km.

But I actually know so many taxi drivers. A car has been driving for eight years and traveled millions of kilometers. There are at least dozens of taxi drivers I know, and none of them have changed the gearbox oil.

There has never been any problem with the gearbox. I have to say that the manual gearbox is anti-operating. If it is difficult to shift gears and operate during use, you can change the gearbox oil. Usually you can get rid of the disease if you change it.

The battery needs attention.

The battery depends not only on how many tens of thousands of kilometers it has run, but also on its service life. Under normal circumstances, if you are an ordinary private car, you should have run 65438+ 10,000 kilometers for three or four years.

At this time, the battery is the key observation object. If your car is a manual transmission, fortunately, there is no electricity, you can ask someone to help push it.

If it's automatic, it won't work. I once tried to drive to buy food, but there was nothing unusual when I went. I just can't hit it when I come back from buying vegetables.

My friend drove to the gas station to refuel, but when he got there, he would be fine. When he was full, he couldn't get a taxi.

We all hope that we have replaced the battery. The battery is dead. But he didn't have any signs. If it is a manual transmission car, the battery is generally dead, and there will be some signs. For example, I missed it several times and was forced to hit it in the end.

Automatic transmission really doesn't have any signs, and it won't happen if you can't say it.

So when it is about 65438+ 10,000 km, you'd better prepare a dragon crossing the river in the car and let others help you catch the fire. You can drive to change the battery, or you can go to the e-commerce platform to buy backup power. This thing is worthless, just a few tens of dollars. Put it in the car and the battery will die. You can call your car directly without asking others.

Brake pads also need attention.

Generally, it is about 65438+100000 km, and the brake pads should be replaced almost. You don't need to see if it needs to be replaced.

If one day you step on the brakes, there will be some mechanical friction, which proves that the brake pads are worn. At this time, you can drive to change it immediately.

Don't worry, even if the noise is abnormal, the braking performance is generally no problem if you run for one or two thousand kilometers. Just don't delay. Once this abnormal sound occurs, you'd better drive to replace it at once.

Spark plug

Theoretically, this thing will be replaced around 60,000 km, but in fact, I am optimistic that many people have run away, and1.5,000 or 200,000 km has not been replaced.

You don't have to go many kilometers away to replace it. Run first. If the car feels that the fuel supply is not smooth when driving, go to the garage and let him check it. If it is a spark plug problem, it is not too late to replace it at this time.

Ignition coil (high voltage component)

I don't know the theoretical replacement kilometers of this thing. In fact, it is generally about 65438+100000 km ~ 15000km, and I have seen those that have not been replaced over 200000 km.

If one day, your car wobbles, just like a tractor. That's mostly because there is something wrong with this high-pressure bag. Go to the garage and check on the master. If so, replace it directly.

There are many high-pressure bags, one for each cylinder. For example, your car has four cylinders in a row, so there are four. If your car is V6, there are six.

If you want to save money, change which one is not good, and if it is not bad, change it together. Because as long as the first one begins to decompose, the later ones will generally expire one after another.

Timing belt (timing chain)

Some cars are timing chains, others are timing belts. If you don't know what your car is. When you change the oil, ask the mechanic.

If the timing belt is used, it must be replaced within 654.38+ million kilometers. I suggest you follow the maintenance manual. He said that if you change tens of thousands of kilometers, you can change tens of thousands of kilometers. Even if it's not broken, change it.

Because once this thing breaks down, it may cause your engine to be scrapped directly, and the consequences are very serious. You can't save the money just because of a small loss.

If it is a timing chain, it does not need to be replaced and will not break.

Vehicle lubricating oil

Vehicle lubricating oil, brake oil and coolant. According to the maintenance manual, it is also about 30,000 to 40,000 kilometers, or 50,000 to 60,000 kilometers.

But in fact, this kind of thing does not need to be replaced for almost a lifetime.

I have driven a lot of cars over 200,000 km, all of which are driven by me (including taxis and drip cars), and I have never changed them. My colleagues have never changed.

Look at the scale of the coolant yourself, and add it if it is less. What color is your original car? Just buy it and add it.

Both lubricating oil and brake oil are IQ taxes. Except for those who were fooled by going to the 4s shop, basically no one changed. Everyone is running well, and the brakes are also leveraged.

When the mileage of a car reaches 6,543,800 kilometers, it is a major turning point to decide whether to keep, sell or scrap the car. According to statistics, the average car ownership life is 14 years, and the service life is on the rise.

First of all, the deterioration state of automobile can be divided into four stages to consider.

A new car with a short mileage.

A new car with a long mileage.

An old car and a car with a short mileage.

An old-fashioned car with a long mileage.

The new car with short mileage is in the best condition, while the old car with long mileage is seriously aging and in poor condition. Of course, whether some vehicles are in good condition depends on the maintenance and the replacement of parts.

The parts that cannot be replaced, such as the chassis, are difficult to control and are likely to be worse than new cars. For new models and cars with long mileage, it is unlikely to break down because of aging.

On the other hand, all parts of an old car with short mileage are aging, and even if it is not rough driving, problems may occur.

If it is a new model that has traveled100000 kilometers, it does not mean that parts must be replaced. So, what parts should be replaced for old cars with long mileage?

① synchronous belt

The typical100,000 km replacement part is the timing belt. Timing belt is the belt connecting crankshaft and camshaft inside the engine.

The replacement cycle of timing belt is 6.5438+10,000 kilometers, which is a very important link in engine operation. If the belt breaks, the engine won't start at all.

② Brake pipe

It is recommended to replace the brake hose after driving 100000km. Do you know what will happen if the brake pipe leaks oil?

If there is a small amount of leakage, there will be no symptoms, but if there is a large amount of leakage, the worst case is that the brakes will not work.

Of course, if it is replaced before 654.38 million kilometers, there is no need to replace it unless there is air leakage. Be sure to check whether the hose is aging when checking.

③ Shock absorber

Shock absorber is a component installed on the tire, which has the function of absorbing vertical impact. There are many old cars making noises like "squeaking" and "rumbling". One of the causes of abnormal sound is the shock absorber. If it reaches100000 km, it is better to replace it.

④ Spark plug

Spark plugs are components that ignite compressed air-fuel mixtures. At present, "Iridium" spark plug has become the mainstream, and the replacement cycle is 654.38+ 10,000 kilometers.

In addition, the replacement cycle of standard spark plugs is 10000 to 20000 km. Check what plugs are used in automobile spark plugs, and replace iridium spark plugs after driving 100000 km.

⑤ Water pump

The water pump is a component that provides power for the cooling water circulation in the engine. Cooling water is pumped into the engine by a water pump to cool the hot engine. It is recommended to replace this component at 100000km. If the water pump is broken, the cooling water can't circulate in the engine, which will cause the engine to overheat and burn, thus causing a major failure.

⑥ Seal around the brake.

Replacing the brake oil pipe was introduced before, but the "wheel cylinder cup seal" and "caliper piston seal" installed on the brake also leaked oil.

⑦ Throttle controller

Thermostat is a part that may break down 654.38+10,000 kilometers ago, but if you have never replaced it, it is recommended to replace it at 654.38+10,000 kilometers.

The thermostat closes the valve when the engine is not hot, and opens the valve to let the cooling water flow when the temperature rises, thus lowering the engine to a proper temperature.

8 Oil pump gasket

The longer the mileage, the more likely the oil will leak or ooze from the gasket of the oil pump. Like the water pump, it is a part installed inside the engine and needs to be disassembled and replaced. Unlike the water pump, the oil pump is a component with less faults such as oil leakage, and only needs to replace the gasket.

Summary: It is recommended that the timing belt, water pump and oil pump gasket be used as internal parts of the engine and replaced at 100000km. There are also some ball wheel protective sleeves, door sealing rings, upper and lower arms, etc. , can be decided according to the actual situation.

Make a big insurance and look at the chassis. If nothing happens, nothing needs to be changed. But all kinds of semi-sealant sleeves and ball heads should be looked at and oiled.

65438+100000 kilometers is equivalent to human youth for a car. Only the tires must be replaced. As long as the others are properly maintained and not sick, nothing needs to be changed.

Looking back, a Japanese B-class car that has been driving for ten years has a mileage of more than100000 km. During this period, engine oil, machine filter, air filter, air conditioner filter, etc. Replace it regularly according to the instructions. So far, the car is in good condition. 20 19 10 (more than eight years) The bumper was scratched before parking in the parking lot, and the other insurance company accompanied it to replace it; 20 19 12 (eight and a half years) replaced the original battery; In May of 20021year (ten years), the original rain scraper was replaced; 202 1 (more than ten years) In September, four original Michelin tires were replaced ... Other than that, they were all original parts.

Three filters (oil filter+air filter+air conditioner filter)

Doing a good job in the maintenance of "three filters" plays a very important role in the maintenance of automobile engines and driving safety.

Spark plug

Once there is something wrong with the spark plug, the car will not catch fire. So 50,000 kilometers is basically the limit of most spark plugs.

brake pad

Brake system is one of the most important safety features of automobiles. Whenever possible, check the thickness of the brake pads regularly. Once it is less than 3mm, do not hesitate to replace it in time.

Engine timing belt

Engine belt is rubber, but during normal use, timing belt will cause aging loss. If the timing belt breaks, it is likely to cause serious damage to the engine.

I can't change anything except engine oil. If it is broken, Jingyi X5~ 8 years180,000.

Geely emgrand 15 manual version, 15 1 1 month. There is still more than 500 kilometers to go, and it is 654.38+10,000 kilometers. The tires are original and exquisite. More than 40,000 tires have been replaced with steam filters, brake oil and transmission oil. Everything else is routine maintenance. It is maintained once every 7,500 kilometers, using half synthetic engine oil. The belt has been checked and there is no aging problem. The younger brother of the auto repair shop asked if the belt had just been changed. It looks very new, without aging and cracking, and the brake pads are less worn. Tire wear is also very light, and I always feel that aging will be unsafe after a long time. I plan to change it at the time of 65438+ million maintenance.

Because it is manual, there is nothing wrong with the gearbox, except that the clutch is worn, and the sound of stepping on it is not very loud, so you can hear it clearly in the car. Now the cold car is ignited until the car starts, and the speed is more than 700 and less than 800. It is more worry-free to use, and I am afraid of traffic jams. When the holiday is blocked on the highway, there is the idea of smashing the car, and the disadvantages of manual transmission are fully demonstrated.

I have a good relationship with the owner of the garage. The car has been carefully inspected. No problem, nothing needs to be changed, and the tires can drive tens of thousands of kilometers [I want to be quiet]. I feel that this car eats coarse grains and is resistant to exercise. It is very worry-free to use, but it does not preserve value. ...

The residual value of the policy is 36,806, and the actual used car market is 25,000 [tears streaming down her face].
