Timing belts typically consist of multiple layers of polyester fabric with a rubber inner layer. The layers are then sewn together and the material is then vulcanized.

Different types of timing belts:

  • -V-Belt: This belt is made of a single loop of material that runs around the entire circumference of the pulley and attaches at both ends to the belt cover on each side. It has teeth or notches on one side for engagement with a V-shaped groove in the pulley.
  • -Double V-belt: Similar to a single v belt, this belt is made up of two loops which run around opposite sides of the pulley and attach at both ends to the belt cover on each side. The difference is that one end has three notches.

Timing Belt Problems After Replacement

Timing belt problems are quite common after replacement. The problem is that the replacement part does not fit in the engine properly and it creates a lot of friction and noise.

Some of the possible causes for this problem are:

  • – The timing belt didn’t come with a new gasket (the old one was not removed properly).
  • – The new timing belt was installed by an inexperienced mechanic who didn’t use the right tools to install it.
  • – If you have replaced your timing belt before, there’s a chance that you skipped a tooth on the old belt.

How to Tell if Timing Belt is off a Tooth

If you are experiencing a grinding noise from your engine or if the car is jerking, then it is time to check the timing belt.

Timing belt is a cog that connects the crankshaft and camshafts and it needs to be replaced every 60,000 miles or once every four years.

Incorrect Timing Chain Installation Symptoms

Many people are unaware of the importance of timing chain installation. They often neglect to follow the recommended installation procedures which can lead to serious damage.

A timing chain is a belt that connects your engine’s camshaft and crankshaft, causing them to rotate in unison. It is important for the engine to have a proper timing chain because it increases fuel efficiency by reducing friction and wear on other parts of the engine.

The installation process should be done by an experienced mechanic who knows what they are doing. If you notice any symptoms such as rough idling, stalling, or difficulty starting your vehicle after installing a new timing chain, it is best to contact an experienced mechanic right away.

Symptoms of a Bad Timing Belt In Toyota

The timing belt is a crucial part of your car’s engine. It is used to synchronize the rotation of the crankshaft and camshaft. If it has been worn out for a long time, it can cause serious damage to your car’s engine.

Symptoms of a Bad Timing Belt in Toyota:

  • – Engine won’t start or stop suddenly when you press the gas pedal.
  • – Engine backfires or stalls when you release the gas pedal.
  • – Engine backfires or stalls when you press the clutch pedal.
  • – The engine will not start.
  • – The engine will stall intermittently when you are driving or accelerating.
  • – There will be no power from the engine when you are driving or accelerating.
  • – There may be an unusual noise coming from your engine when it stalls or does not start.

What Causes Timing Belt to Break

Timing belts break due to the fact that they are designed to be stretched with a certain amount of force. This force is applied by the engine and it can cause the belt to break.

Timing belt breakage is a common problem in cars, especially on older cars that have been driven for many miles. The timing belt is an important part of any car and if it breaks, you need to replace it immediately or risk serious damage to your engine.

Bad Timing Belt Tensioner Symptoms

The timing belt tensioner is a component of an internal combustion engine. It is a device that regulates the tension of the timing belt, which is used in order to drive the crankshaft to rotate.

The timing belt tensioner has two components, the tensioner and the idler pulley. The idler pulley is fixed and does not move, but it has a hole through which it can be attached to the tensioner.

The tensioner has a gear on its input shaft and an output gear on its output shaft, which are both connected by a chain.

The symptoms of bad timing belt tensioner can be as follows:

  • Trouble Starting The Vehicle.
  • Acceleration Issues.
  • Strange Noises.
  • Rattling noises.
  • Squeaking or squealing noises.
  • Knocking noises.

The symptoms of a bad tensioner can be very difficult to detect, especially when it comes to the noise it makes. That’s why many people are turning to technology for help in this situation.

Distributor Timing off Symptoms

Distributor Timing off Symptoms is the most common diagnosis for engine knock. This is because it is a symptom that often leads to a major problem with the engine.

Distributor Timing off Symptoms can also be caused by other problems, such as an air filter problem or a faulty fuel system. It should not be confused with other types of engine noise, such as a clogged catalytic converter.

The symptoms of Distributor Timing off Symptoms include:

  • – Engine knock (a rapid knocking sound)
  • – A hesitation in acceleration or deceleration when accelerating or slowing down at low speeds, respectively.

Some people may also experience an unusual hesitation when accelerating from high speeds and then suddenly changing gears without letting up on the accelerator pedal.

What happens if timing belt is put on wrong?

What happens if timing belt is put on wrong? I have addressed this before but i will say it another way again. For better understanding, a correctly installed timing will synchronize the movement if of the camshaft and the crankshafts.

This harmonized movement makes it possible for cylinder’s intake and exhaust strokes to possible. This complete cylinder’s intake and exhaust strokes is what make the engine run.

On the other hand, if timing belt is put on wrongly then the opposite would happen. In fact in some modern engines, wrong timing installation can cause a damages to the engine.

If the timing belt fails in an interference engine, it will bend valves in the cylinder head, requiring very expensive engine repairs. It is advisable to always inspect your timing belt for any bad symptoms when changing engine oil.


Can I replace timing belt myself?

Timing belt replacement is not for and average driver or car owner with little to know technical know how. However the process of replacing a broken timing belt is not so hard.

If you love to get your hands dirty and do your auto jobs by yourself then you should carry on. All you need an handful first hand knowledge of how it works, new timing belt and technical know how. Below is a list of all the tools needed for a successful replacement

  • Socket set
  • Torque wrench
  • Combination wrenches
  • Screwdrivers
  • Jack and jack stands
  • A new timing belt

It is a not bad to take your car to a professional for belt replacement if you don’t know how to. But if you are and you enjoy doing your own repairs or restorations then it’s something you can do yourself, and save on some big repair bills in the process.


Does a bad timing belt affect acceleration?

Can bad timing belt affect acceleration? Simple answer to this is yes, acceleration can be affected. Your intake and exhaust valves won’t open and close at the right times, which can cause misfires or less acceleration power.

If the valves does not open and close at the right time, it indicate that the camshaft and the crankshaft are not properly timed. A worn timing belt can slip, getting out of the proper alignment.

This means that the valves and pistons are no longer perfectly synchronized. This can lead to the piston smashing into the valves, causing catastrophic damage leading to expensive repairs.


Can a timing belt last 200 000 miles?

Whether or not a timing belt can last 200,000 miles all depends on several factors including the vehicular mode of use. Nowadays timing belts do not last like they used to in the past decades.

Many years back timing belt have been reported to last 7 to 10 years without having any problems. Some Americans happen to even forget about anything called timing belt replacement because of how long they lasted.

However, like i said before the lifespan of a timing belt depends on several factors. Some of this factors includes manufacturer, mode of vehicular use and even climate condition.

In some cases the type of vehicle also matters when it come to the lifespan of a of timing belt. Whatever the case might be, just remember that timing belt do not last like they used to be fore, so a close observation is important.


Does timing belt give warning?

Timing belt might and might not give any warning signs before breaking, it can break at any time. However, a worn-out timing belt would show some signs and symptoms that would indicate that something is wrong.

Signs of a worn-out timing chain or belt includes the an occasional engine misfire, rattling sound, low oil pressure, rough idle and a stretch timing chain. All these are signs and symptoms of a worn timing belt.

Timing belt can fail without any prior symptoms, so if you’re within the mileage window, you should go ahead and have it replaced regardless. That being said, sometimes your car will give you a bit of warning that the belt is wearing out.


What happens if valve timing is incorrect?

If the valve timing is incorrect, not only will the engine not run, but the piston could smash into the valves, causing catastrophic damage. Most likely, it will lead to bent valves and damaged pistons.

If the crankshaft and the camshaft cannot turn at the same time then cylinder’s intake and exhaust strokes will not be possible. If cylinder’s intake and exhaust strokes is not possible it means car would not start, this is a simple term.



Timing belts are used in the engine of your car, and if they break, it can lead to an expensive repair. They are also a common problem for many older cars.

A timing belt is a belt that connects all the components of an internal combustion engine’s timing system. It rotates the crankshaft with its pulleys and gears, which in turn drives the pistons up and down so that they move back and forth within their cylinders.

Timing belts are made from a tough rubber material, but over time the rubber hardens and wears out. This causes problems such as broken teeth or misalignment of teeth, causing slippage and failure of the belt. The most common time for this to happen is when you replace your timing belt.
