What is a Timing Belt, What Does It Do?

Timing belt rupture, which is one of the most important parts of the engine parts of cars, is one of the most common causes of vehicle repair. So, what is the timing belt, what is the use, and when it breaks, should it be intervened immediately? We explained the details about the timing belt and answered the question of when it should be changed.

Even if you don’t drive or have never seen engine parts before, at least in one movie scene, you can lift the engine oil-covered master’s head off the hood. ‘The timing belt is broken, it needs to be replaced.’ you’ve heard it said. All concerned, irrelevant people what is timing belt The reason he knows is that this part is of vital importance to the car engine assembly and therefore to the car.

What is a timing belt, what does it do, when should it be replaced Questions like these are among the most frequently asked questions. This is because no one timing belt not wanting to be in the middle of the road with a broken-down car We answered all the questions about this important part of the vehicle engine and explained the important details you need to know about the subject. It is quite surprising that a great engineering marvel can rely on a tiny belt.

What is timing belt?

The timing belt, which has different names such as camshaft belt and timing belt, receives the movement from the crankshaft and transmits it to the camshaft. forwarded Thanks to this movement, the valves continue their opening-closing movement. and thus the engine coolant is distributed throughout the system.

In some vehicle models, the timing belt also provides the basic recirculation system to work. Thanks to the timing system consisting of three basic parts engine coolant spreads everywhere and even when the engine is forced, it is prevented from overheating and malfunctioning.

What does the timing belt do?

Timing system; It consists of the tiger belt that transfers the movement between the shafts, the tension ball that ensures the correct alignment of the belt between the shafts and allowing engine coolant to flow through the entire system. It consists of a circulation pump. The timing system is a whole, it cannot be divided. In other words, if any part of the system fails, the whole must be replaced.

At intervals determined by the manufacturer according to the make and model of the vehicle. timing belt placed on the crankshaft and camshaft gears, It is the most important part that makes the whole system work. A timing belt that is not installed correctly as a factory defect or later will disrupt the operation of the system and cause engine failure.

When should the timing belt be changed?

There are two points to consider for timing belt replacement; duration of use and how many kilometers the vehicle has done. According to the make and model of the vehicle, it is understood that it is time to replace the timing belt depending on these two variables. Moreover, even if there is no visible damage to the belt or the system, the belt should be replaced for safety reasons.

Service life of timing belt maximum of 3 years. After 3 years, the timing belt must be replaced. Mileage where the timing belt will be used a maximum of 100 thousand. The timing belt of a vehicle with 100 thousand kilometers must be changed. Depending on the make and model of the vehicle, this period may be a little shorter or a little longer.

Timing belt is generally made by combining steel wire, fabric and rubber components. In some belts, carbon fiber, kevlar and aramid stronger materials can be used. The quality of these materials can also determine the belt replacement time. However, the mileage to be considered in general is 100 thousand and the duration is 3 years.

There is also something called a timing chain:

It will be because it doesn’t make sense to anyone to entrust a great engineering marvel engine assembly to a belt made only of steel wire, fabric and rubber. timing chain with the same function A piece called the The timing chain is all steel and lasts much longer.

Well, if you say why the timing chain is not used in vehicles, as every beauty has a sin. The timing chain also has negative features. In long-term use, the timing chain gears wear out, the chain elongates due to heat, and different problems arise in the general system due to hard material. That’s why the timing belt is still seen as the most advantageous option.

What happens if the timing belt breaks, what should I do?

If you suddenly hear strange sounds coming from the engine while you are on the road, or if you see the exhaust fumes are blacker than ever First of all, calmly pull the car to the right. When you lift the hood and look, even if you are not a master, you will understand that the timing belt is broken.

When the timing belt breaks, the valve timing is broken, the valves stay open, the valves hit the pistons, the valves bend as the pistons hit, there is stress on the connecting parts and With a big noise, the engine suddenly stops. This is why it is extremely important to stop the car and pull over when you suspect that the timing belt has broken.

Considering that you do not carry a spare timing system in the trunk of the car, in such a case You should definitely call roadside assistance. Do not start the car and wait for support, even if the service is close to your location. If you stubbornly continue to operate a vehicle with a broken timing belt, irreversible damage may occur to the engine.

We answered questions such as what is a timing belt, what is it for, how does it work, when should it be changed, and about this important part of the engine assembly We told you what you need to know. Even if you are experienced in vehicles, do not forget to get help from experts in case of timing belt breakage.
