Timing belt is a rubber belt or a chain that controls the valve timing to generate the spark
for combustion.

It is the most important part of combustion that
synchronizes the engine's functions.

During combustion, it controls the rotation of the camshaft and crankshaft that allows the right amount of air in and out for proper
combustion.

What happen if the timing belt fails?
![Page 6: How Does Timing Belt Work In Vehicles](https://reader031.vdocument.in/reader031/viewer/2022020314/5873dd9e1a28abd72e8b5191/html5/thumbnails/6.jpg)
If the timing belt fails, it affects the valve timing that
forces the engine run rough or not run at all.

If the timing belt breaks, the valve will open in wrong time and hit the piston that causes damage to the engine.

When to replace the timing belt?
![Page 9: How Does Timing Belt Work In Vehicles](https://reader031.vdocument.in/reader031/viewer/2022020314/5873dd9e1a28abd72e8b5191/html5/thumbnails/9.jpg)
As per owner's manual, you should replace it in every 60,000 to 100,000 miles.

But some vehicle owners usually replace when it breaks.

How does it work inside the engine?
![Page 12: How Does Timing Belt Work In Vehicles](https://reader031.vdocument.in/reader031/viewer/2022020314/5873dd9e1a28abd72e8b5191/html5/thumbnails/12.jpg)
In a standard engine, there are 4 key phases
or “strokes” present.
![Page 13: How Does Timing Belt Work In Vehicles](https://reader031.vdocument.in/reader031/viewer/2022020314/5873dd9e1a28abd72e8b5191/html5/thumbnails/13.jpg)
The prime responsibility of the timing belt is to control these strokes and make sure to open and close the valves in the right
time for a proper combustion.

:- The intake stroke :- The compression stroke :- The combustion stroke
:- The exhaust stroke

What are the other reasons of incorrect valve timing?
![Page 16: How Does Timing Belt Work In Vehicles](https://reader031.vdocument.in/reader031/viewer/2022020314/5873dd9e1a28abd72e8b5191/html5/thumbnails/16.jpg)
The problematic timing belt can be absolutely disastrous for the engine. The reasons are
:- Bend valve :- Bend piston rod
:- Damaged pistons etc.

How to spot Timing Belt Problems?
![Page 18: How Does Timing Belt Work In Vehicles](https://reader031.vdocument.in/reader031/viewer/2022020314/5873dd9e1a28abd72e8b5191/html5/thumbnails/18.jpg)
Tensile problem :- it happens due to excessive installation tension or belt crimped due to improper handling etc.
![Page 19: How Does Timing Belt Work In Vehicles](https://reader031.vdocument.in/reader031/viewer/2022020314/5873dd9e1a28abd72e8b5191/html5/thumbnails/19.jpg)
Tooth shear :- The causes are low tension or
misalignment.

Tooth wear :-It happens due to incorrect tension or worn out pulley.

Back cracks :- it happens due to high or low temperature
and worn out back idler.

Belt Noise :- It happens due to high or low tension, misalignment and damaged flange.

Vehicle won't start :- It's the important setback of timing belt. if it is broken, the vehicle doesn't start until you change the damaged
belt.
