How many kilometers does the engine belt change, and how many kilometers does the engine belt change

In cars, belts are a very important thing. It is usually the main medium connecting the crankshaft of the automobile engine and the air conditioning compressor, generator and water pump on the car. When the automobile engine is in operation, the precise control of the intake and exhaust of the car can only be achieved through the operation of the timing belt.

So, how often do you need to replace the belt on a sedan?

Because most of the belts on the car are made of rubber, it is inevitable that they will gradually wear out and age in the long-term high-temperature work. Therefore, generally speaking, the belt replacement manufacturers on the car have regulations, which are introduced and clarified in the vehicle's on-board maintenance manual. According to the usual car maintenance specifications, it is about 60,000-80,000 kilometers, and a small number of them can be replaced at 80,000-100,000 kilometers.

Some brothers may want to ask, rubber belts will age over time, so why not think about using some other materials for transmission, such as gears? There's a reason for this, rubber belt drives are more accurate than gear drives and are less noisy. Compared with gear transmission, the belt transmission structure is more simple, more convenient for maintenance, and the cost will be lower in comparison, and it is easy to adjust when replacing it in the later stage.

The belt drive is relatively stable and has an overload protection function. Therefore, car manufacturers prefer belt transmission more and more, rather than using gear transmission.

Every time the car goes to a 4S shop or repair shop for maintenance, you must remember to ask them to check the aging degree of the belt. If there is a crack on the belt, then the belt should be replaced in time, otherwise if the belt cracks on the road, then the car engine will not be able to work normally. If the timing belt of the car is cracked, the car will be paralyzed on the road, which is very risky for cars traveling at high speeds.

If the belt of the car's generator and water pump is cracked, the car generator will not be able to generate electricity normally, the battery will not be able to be charged normally, and the car will not be able to operate after the power is exhausted. If the water pump cannot be operated, the coolant of the car will not be able to circulate normally, and the water temperature of the engine will soon be too high.

Therefore, these small things of the car should also be maintained frequently, and the usual car advocates replacing the timing belt in two years. Of course, many car timing belts are now upgraded to timing chains, which can usually be used until the car is scrapped. However, the generator and pump belt of the car should be replaced every 6-80,000 kilometers, and it should be checked in a year and a half, and it should be replaced in two years, so that the car will continue to operate steadily.

Don't think of replacing the car when it can't move, and then the gains outweigh the losses.

The engine has 3 belts; 1.The timing belt should be replaced at 60,000 kilometers; 2.The generator belt should be used according to the situation, and generally the belt should be replaced if there is a crack or 2 years; 3.Air conditioning and power steering belts.

The engine belt is about 80,000 kilometers to change more appropriate, too early to replace is a waste, in fact, the timing belt life can reach 100,000 kilometers, but for the sake of safety, or 80,000 kilometers to replace, otherwise it will be broken during driving, the consequences are very serious, and the engine should be overhauled. It is recommended that when replacing the timing belt, the timing belt assembly should also be checked.

Since the engine belt is an important part of the engine, in order to avoid problems with the engine,The 4S shop will require that the timing belt should be replaced after driving about 60,000 kilometers, and if it is a new car, the timing belt will generally run 8-100,000 kilometers. In order to ensure the service life of the engine, it is recommended that the timing belt be replaced in 1 and a half to 2 years, or pay attention to the replacement of the timing belt after driving about 60,000 kilometers.

Once the timing belt is broken, the camshaft valve sequence will not run according to the timing, which is very likely to cause the valve and the piston to collide and cause serious damage to the engine, so the timing belt must be replaced according to the mileage or time specified by the original factory, otherwise the consequences are very serious.

Symptoms of aging of timing belts.

The aging of the timing belt cannot be felt when driving, and the timing belt must be checked and observed with the naked eye. Carefully inspect the belt for visible cracks, fluffing, or rubber hardening. It is best to replace the timing belt in strict accordance with the number of kilometers, but if there is abrasion, fiber breakage, and cracks, it should be replaced even if the kilometers are not reached.

If the timing belt suddenly breaks during the high-speed driving of the vehicle, it will cause the engine top valve, and the power will also disappear, accompanied by a strong metal collision noise, the engine will also be seriously damaged, and it is very dangerous, and it is likely to cause a serious car accident. The timing belt is an important component of the engine valve system, which ensures the accuracy of the intake and exhaust time through the connection with the crankshaft and a certain transmission ratio.

The time requirements for replacing timing belts for each brand of car are inconsistent, generally between 60,000 and 100,000 kilometers.

More than 50,000 kilometers should be checked frequently to find out whether there is any abnormality in the timing belt in time. The main thing is to listen to the sound, and generally if there is any wear and tear, there will be a precursor, such as abnormal noise. or odors due to abrasion.

The replacement time is clearly stipulated in the maintenance manual of the car.

Check whether the belt has cracks and aging, since the 4S shop recommends that you replace it, it is better to replace it, because if the vehicle is driving if the timing belt is suddenly broken, it will bend the valve inside the engine, which will cost a lot of money, so don't save a little money, pay attention, and the belt of the generator, but also check whether it is aging.

When changing the engine belt, the timing must be aligned before removing the timing belt, and the tensioning wheel can be removed only after the timing is right, and then the belt can be removed, and try not to make the mark wrong when installing the belt; After installing the belt, you should first use a wrench to turn the crankshaft twice, and then look at the mark, if the mark is right, then install other things on it, most cars are now easy to top the valve, so the timing mark must be right.

Timing belts have a lifespan. It is all explained in this user manual. Most models are 100,000 km. It is recommended to replace it for about 90,000 kilometers. In addition, if the timing belt is stained with oil, it will seriously shorten the service life.

The timing belt is an important part of the engine valve system, which is mainly responsible for the connection between the crankshaft and the camshaft (some models also drive the water pump and balance shaft, and the diesel engine also drives the fuel injection pump), and cooperate with a certain transmission ratio to ensure the accuracy of the intake and exhaust time. The belt is used instead of gears for transmission because the belt is quiet, the transmission is accurate, the amount of self-variation is small and easy to compensate.

Obviously, the life of the belt is definitely shorter than that of the metal gear, so the belt should be replaced regularly, and the timing belt is easy to break when the service life is exceeded. When the timing belt is broken, it will cause the valve phase to be misaligned, so that the engine cannot start, and in some models, the valve will be bent upward. Causing serious mechanical failure, the cost is more than n times the value of the timing belt.

Therefore, it is still necessary to replace it on time according to the requirements of the user manual. And go to a 4S shop or repair shop for a proper replacement.

Hello, I am your exclusive technician, attentive, careful, dedicated to answering your car questions, for you to find the corresponding problem solutions and solutions! The engine timing belt, I personally recommend replacing it once at 80,000 km. Engine timing belt, I recommend replacing this original timing belt, this is the first choice.

Then the timing belt of Gates used by domestic brands is also very good. The quality of the domestic brand Gates is still very good, and it is worth choosing. **It is also very affordable, I hope my answer can help you, I wish you a happy car.

There is nothing definite in kilometers. The use environment is different, the strength is different, and the aging rate of the belt is also different.

There are timing belts, generator belts, air conditioning compressor belts directly and near the engine. Generally, it does not fail and does not need to be replaced. Generally, the idle speed is unstable and the acceleration is weak, check the timing belt, correct or replace.

The generator is in poor working condition, and the power generation is insufficient, so replace the generator belt. The air conditioner is not working or there is a noise, or the refrigeration is weak, check or replace the compressor belt.

The engine timing belt requires 80,000 to 10 times to be replaced, and the generator and compressor booster pump belt check the degree of aging, generally 30,000 times to replace it.

The timing belt manufacturer of new cars generally replaces it for 80,000 kilometers. In fact, when it comes to the specified replacement period, you can let the 4S store check it first to see if it is really aging and has cracks, and if so, replace it. Otherwise, it is better not to change it first, the replacement cost of the timing belt is much more expensive than the general maintenance, and there is a little bit of the timing belt that will break the top valve, so be sure to grasp whether to change or not to change, if the valve is broken, it is even more cost-effective.

Check whether the belt has cracks and aging, since the 4S shop recommends that you replace it, it is better to replace it, because if the vehicle is driving if the timing belt is suddenly broken, it will bend the valve inside the engine, which will cost a lot of money, so don't save a little money, pay attention, and the belt of the generator, but also check whether it is aging. If you change it, you change it.

.The timing belt should be replaced at 60,000 kilometers; The generator belt should be used according to the situation, and generally the belt should be replaced if there is a crack or 2 years; Air conditioning and power steering belts.

The engine belt is generally replaced after the vehicle has traveled 4-80,000 kilometers. The engine belt is the most important drive belt in the car, connecting the generator, air conditioning compressor, booster pump, bridge wheel (idler), tensioner and crankshaft pulley. Its power source is the crankshaft pulley, which then drives the other components to run together.

When a small crack occurs on the surface of the belt in contact with the pulley, it needs to be replaced. If there is a break, it will cause the generator to fail to generate electricity, the booster pump will fail, and the direction will not be moved, which is a very dangerous situation.

The timing belt is easy to age during use, the life is short, there is almost no warning or sound before damage, and the damage to parts such as groove doors, conduits, and even camshafts after damage. Therefore, timing belts must be replaced regularly. The gasoline engine is replaced with a perimeter of 80,000 to 100,000km, and the diesel engine is generally 60,000km, which is generally replaced.

The timing belt travels 6 to 80,000 kilometers to replace, the timing belt is a wear and tear, and once the timing belt is broken, the camshaft will not run according to the timing of course, which is very likely to cause serious damage to the valve and piston collision.

The number of kilometers required to be replaced is not the same for each model.

It is recommended to consult the repair manual for introduction.

The general maintenance manual recommends replacing it once every 6-100,000 km.

If the timing belt breaks, it will cause a lot of damage to the engine.

The timing belt is generally replaced at 6-8w kilometers, and it is recommended to refer to the vehicle maintenance manual for the number of kilometers of replacement time.

The timing belt is very important for the normal operation of the engine, once the timing belt is damaged, the valve, ignition work will stop and will not work, and in serious cases, the cylinder head will be damaged.

As the engine working time increases, timing belts and their accessories, such as timing belt tensioners, timing belt tensioners, and water pumps, etc., will wear out or age, so carefully check whether these accessories are good every time you replace the belt.

When in use, it is necessary to regularly check the use of the timing belt, if you see cracks on the surface of the timing belt, you need to pay attention to whether the timing belt is aging, there is abnormal noise when driving, and you need to pay attention to whether the timing belt is installed correctly.

The belt replacement time is maintained at six years, or the car must be replaced in time after 100,000 kilometers.

The dangers of not changing:

1. If the belt is broken, there are often some cracks first, or it will become very hard due to aging. At this time, if there is no maintenance, there will be tooth loss, and then the engine will also jump teeth, and in serious cases, it will be directly broken.

2. The belt is broken, coupled with its own inertia, resulting in the camshaft will still run non-stop, but due to the loss of the matching role of the belt, the two will run freely, and the movement of the piston and the valve will be inconsistent, resulting in non-stop impact, and both will be damaged in serious cases.

Timing belt advantages.

Automobile belts have been used in engines for a long time, the technology is mature, the cost is low, and the noise is small, but it needs to be regularly inspected and maintained, and generally needs to be replaced after 5 100,000 kilometers. The timing chain has the significant advantages of compact structure, high transmission power, high reliability and wear resistance, and lifelong maintenance-free, but compared with the traditional timing belt, its noise is generally slightly larger.

But nothing is absolute. With the advancement of technology, some cars have adopted toothed silent chains, which are even less noisy than timing belts. It is believed that the widespread use of this timing chain will bring more convenience to the majority of car users.
