Car engine timing belt, how often to change it is better

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 model is not the same, the belt life is not the same, there is a manual, you can refer to, the general timing belt is about 5-60,000 kilometers to change is more appropriate, too early to change is a waste, in fact, the timing belt life can reach 100,000 kilometers, but for the sake of safety, or 5-60,000 for the appropriate, otherwise it will be broken during driving, and the consequences will be very serious.

Car engine timing belt, how often to change is better, the specific need to see what brand you are talking about which model, generally for most models for the timing belt replacement cycle should be five years or the car travels more than 100,000 kilometers, you can refer to the requirements of the car's maintenance manual.

The timing belt is an important part of the engine valve system, which ensures the accuracy of the intake and exhaust times through the connection with the crankshaft and a certain transmission ratio. The belt is used instead of gears because the belt is quiet, has little variation and is easy to compensate. Obviously, the life of the belt is definitely shorter than that of metal gears, so it is necessary to replace the belt regularly.

As automobiles become more and more advanced, the workload of maintenance will gradually decrease. Automobile manufacturers clearly stipulate the cycle of regular inspection and replacement of timing belts, as a part of regular maintenance and comprehensive inspection, the maintenance of timing belts should be added to the regular maintenance procedures. If this is overlooked, failure to regularly inspect and replace faulty timing belts in a timely manner can lead to serious consequences.

Timing belts are often hidden behind a cover and can only be accessed depending on the arrangement of the engine and engine compartment. During the inspection, if you see a belt that is not well-maintained and properly tensioned, you should replace the timing belt in time.

Timing belts need to be replaced every 60,000 to 80,000 kilometersThe timing belt is an important part of the engine valve system, which ensures the accuracy of the intake and exhaust times through the connection with the crankshaft and a certain transmission ratio.

The function of the timing belt is to connect the upper and lower parts, the upper connection is the timing wheel of the engine cylinder head, and the lower connection is the crankshaft timing wheel. The timing belt is a consumable product, and once the timing belt is broken, of course, the camshaft will not run according to the timing, which is very likely to cause serious damage due to the collision between the valve and the piston, so the timing belt must be replaced regularly.

A precursor to the breakage of the timing belt.

1. Slight (small deviation) will cause the car to be weak and unable to refuel uphill;

3. The car is driving in the process of sudden idling instability, easy to stall, the main thing is that the accelerator is not smooth, acceleration is weak, when this problem occurs, if the throttle and other circuit components are excluded, at this time it is necessary to think about whether there is a problem with the timing, whether the teeth jump sooner or later;

4. The engine suddenly turns off during driving, if you hear the high speed of the starter when you re-ignite, and you feel that there is no compression, there is only one case that the timing belt is broken.

In general, it is common to replace the timing belt for 60,000 to 80,000 kilometers, and there are also longer ones such as 80,000 and 100,000 kilometers to replace the timing belt. The time is not completely unified, because each brand of car series has its own vehicle requirements, and the specific time can only be subject to the "user manual" that comes with the car when buying the car.

Introduction: In the process of engine work, the cylinder is constantly in the intake, compression, combustion, exhaust four working processes, and the best time of each step is matched with the movement state and position of the piston in the cylinder, so that the intake, exhaust and piston rise and fall are coordinated with each other. That is, the "timing belt" plays the role of a "bridge".

Nowadays with the development of automobiles. In order to ensure that the timing system works more stably, many high-end models use "timing chain" instead of timing belt. Because the internal valve of the engine will be damaged after the timing of the vehicle's timing belt is broken, the engine is more harmful, and the use of "metal" timing chain can make up for this defect.

The timing belt is a rubber part, and with the increase of the working time of the engine, the timing belt and the accessories of the timing belt, such as: timing tensioner, timing tensioner, water pump, etc., are worn or aging by themselves. Therefore, all engines equipped with timing belts will have relevant requirements for automobile manufacturers

Replace timing belts and accessories within a certain period, replacement time standards are not only the same with the structure of the engine, the general car should be replaced within 60,000 10,000 kilometers, and the specific replacement time standard is subject to the relevant instructions of the vehicle "user manual".

Reason for replacement. 1. Service life; For example, timing belts will have different service cycles due to different materials and manufacturers, and they need to be replaced after a certain period of time.

2. If the timing belt is faulty, there will generally be signs: such as engine weakness, abnormal noise, failure to start or long-term starting.

Therefore, the owner needs to consider this part when feeling the above phenomenon, of course, not only this, but also other parts.

3. Due to friction with mechanical parts, dynamic heat, various vibrations or other components (such as transmission wheels), the service life of the belt will also be reduced or weakened, so after a certain period of time, refer to the manual standard, timely or advance inspection, maintenance, when found abnormal or belt cracks, lengthening, breakage, should be replaced in time. In general, the standard of replacement is according to the requirements of the manual, and it is advisable to advance appropriately.

4. Human reasons: some due to assembly reasons or personal driving reasons, it is also possible that the belt will be damaged and need to be replaced in advance. Therefore, in addition to correct maintenance, individuals also need to pay attention to the first is to choose a professional maintenance company, and the other is to pay attention to personal control and driving.

Generally, 5-60,000 kilometers to change once, once the timing belt is broken, because the inertia crankshaft drives the piston to continue to move up and down and the valve is stationary due to the camshaft stopping, a valve may stop at the lowest point, when the piston of the cylinder moves to the top dead center, it will collide with the valve, the upper end of the valve is a solid cam, can not move, the result is that the valve stem is bent and live.

Pro, there will be a certain disparity according to the different models.

Generally, the lower is 6-70,000 kilometers for replacement; The higher is 8-100,000 kilometers to replace the timing belt (for example, Peugeot 307 stipulates that it must be replaced when it reaches 90,000 kilometers). The replacement time of various brands of cars is different, you can look at the specific provisions of the car's instruction manual (or maintenance manual), and replace it at the specified time.

If the timing belt is faulty, there is generally a precursor, and the engine will produce abnormal noise. Therefore, it is good to listen frequently to see if the engine sound is normal. Especially when approaching the specified (or reached) replacement kilometers, you should pay more attention to whether the engine produces abnormal noises at any time.

It is advisable to replace the engine in advance close to the specified replacement time so that it can avoid accidents or damage to the engine due to breakage in service.

Hope it helps!

The general belt type is 80,000 kilometers, at present, many cars use the engine timing belt has been changed to a chain type, basically there is no need to replace the long-term type, the general car comes with the maintenance manual has this column, you can take a closer look, or ask your car 4S shop, this is subject to the time announced by the manufacturer. Hope the above can help you!

In the instruction manual, the number of kilometers changed is not the same for different models, and the general 6-80,000 kilometers are changed.

Replacement cycle: 6-100,000 km.

The engine belt is a rubber part, and in the normal service cycle, the timing belt will produce aging loss, if the timing belt is broken, it is very likely to cause serious damage to the engine. Therefore, the manufacturer has strict requirements for the replacement cycle of the timing belt, the specific cycle can refer to the user manual of each model, under normal circumstances, the engine timing belt should be replaced after 6-100,000 kilometers.

Slip (squeak), can not be used to change (pay attention to the many fake and shoddy products bought, to buy a brand, look fine).

The general vehicle travels 6-80,000 kilometers to replace the timing belt. The replacement time of the timing belt is not a fixed value, according to the use of the car for a reasonable replacement, in the usual driving process, the timing belt of the car needs to be checked, if there is an abnormality, it should be solved in time, the replacement of the timing belt belongs to the technical work, so you need to find some reliable repair shops to replace, if the replacement is not good, it is easy to appear symptoms such as engine noise. P.S

Reasons for the breakage of the timing belt: 1. Normal wear and tear of the belt: the belt will appear after a certain period of time, such as aging failure, when the core line reaches fatigue life, the belt failure is a normal situation, so it is necessary to carry out a reasonable inspection of the belt when driving, and the factors affecting the life of the belt include the transmission power level, environment, and belt installation tension, which are all things that the owner should pay attention to.

2. Impact load: In the process of driving, if there is a huge impact suddenly, the timing belt of the car may be broken, the impact load may be an inherent part of the operation of the transmission system, or it may be from the accident, the owner needs to reasonably control the timing belt of the engine in the process of driving, so as to avoid the fracture of the timing belt caused by the impact, which will affect the driving safety.

There doesn't seem to be an agreement on this.,,You can check your manual.,If it's not clear in the manual.,You can calculate it according to your usage.。。

<> "Now basically everyone will own a car, because it can greatly enrich people's lives, can make us feel fast and convenient transportation, but there are a lot of useful little knowledge on the car, sometimes we don't pay attention to it may cause a big mistake, today I will take a look at the car use of Xiaochangzi knowledge, can help you grow.

To disassemble the battery, we must know that the battery has a positive and negative electrodes, if you do not pay attention to the positive and negative electrodes in place during installation, the battery may be short-circuited. When you install a new battery in a car, the principle is to first positive and then negative, after installing the battery, let the engine run first, and when the battery is slow, then unplug the battery.

How to judge the car knocking cylinder, this situation is most likely to occur in the winter, because the temperature is too cold, so the water temperature of the Yunxun Qin machine is not normal, in this case, we should not be in a hurry, try not to be in the car is not hot, take high-speed operation, if the engine reaches the sound of normal operation, it should be clear that their car is really injured, quickly sent to the maintenance place, overhaul and then drive.

The requirements for the installation of front and rear tires, some car tires can be used interchangeably, but some car tires cannot, because the pattern is inconsistent, if we are replaced, it has an impact on the airflow when the car runs, so we don't replace the front tires and the rear tires, and some cars are more special, and the front and rear tire sizes are different, so it is even more impossible to reverse.

I believe that if you have learned this knowledge, you must have learned a lot of knowledge.

Car timing belts generally need to be replaced in three years or about 50,000 kilometers, and the time for new cars can be appropriately extended.

The timing belt of the automobile engine should be checked regularly, and there is no specified time or kilometer, as long as there is wear or damage, it must be replaced in time. In particular, if car manufacturers clearly stipulate the cycle of regular inspection and replacement of timing belts, if this is ignored, failure to regularly inspect and replace faulty timing belts in a timely manner can lead to serious consequences.

The function of the timing belt is to connect the upper and lower, and the upper connection is the timing wheel of the engine cylinder head, and the lower connection is the crankshaft timing wheel; The timing wheel is connected to the camshaft, which has a cam on it, and its contact point is a small rocker arm, which generates pressure through the power brought by the timing belt and plays the role of jacking.

The function of jacking the intake valve is to let the atomized gasoline enter the cylinder block, and when the exhaust valve is jacked, it is to let the exhaust gas discharge out of the cylinder block; When the recessed place of the camshaft touches the small rocker arm at the same time, the intake and exhaust valves are closed, the compression ratio is generated, the distributor is ignited, and the internal combustion starts and generates power.
