Which one is a timing belt. we can see around 3 to 4 belts engine to alternator,?

which one is a timing belt. we can see around 3 to 4 belts. engine to alternator, another connecting to waterpump via various pulley. i want to understand that for changing timing bealt weather you need to change all the belts which passes through various pullies or only one belt which has teeth like structure from inside. if timing belt is worn, does it means only the teeth like belt is worn. what about the other belts. is it not necessary to change them??

it would be easier to help you if you stated what car, and you only have to change the timing belt not all of them, its the one you stated that has the 'teeth structure on the inside' it should go to 2 pulley's at the top of the block that are on your camshaft and one pulley at the bottom of the block that is on your crankshaft, unless you have a timing light and know what your doing, i suggest you leave it to a mechanic as you can destroy the engine if its not on correctly, but if you don't have that option and don't mine risking it, take the belt off but what ever you do, don't let the pulleys turn a single notch or it will mess up the timing of the internal functions and could cause that much damage it ends up being cheaper to replace the motor...

The timing belt is a actual belt or it might be a chain simular to a bike chain but heavier and stronger. It is closest to the engine block and usually is completely covered so that if a accessory belt were to break it would not interfer with the timing belt. If the timing belt breaks it can cause major damage to the valve train, making it necessary for a whole new head assembly or rebuild.



When the timing belt is replaced is a great time to install all new belts since you have to remove all of them to replace the timing belt anyway.
It's the belt attached to the crankshaft pulley(the big one on bottom of engine).



The timing belt is usually covered to protect from the elements, It's a good idea to change it according to manufactures routine maintenance charts that should be in your owners manual, if available. An untrained person can do this but I would advise against it if you've never done it or atleast seen it done. If the belt happens to break while going down the road you will have to have the whole top end of motor rebuilt.



Bottom line is spending a little money now will save you lots of money later. As far as the other belts, anyone can change them. Check them for cracking, fraying, if they squill then they may be stretched and worn. To replace, don't forget how the old ones were on, or you might have a diagram showing the belts routing under the hood somewhere.

good luck.
The belts you are looking at are the accessory drive belts, they are completely different than the timing belt. The timing belt can't be seen on the outside of the engine by just peaking under the hood. It is located on the front of the engine on a V6 or V8, and on a Inline 4 cylinder its still on the %26quot;front%26quot; of the engine but typically on the drivers side of the engine compartment due to the fact that the engine is sideways in the car.



If you don't have much experience with cars i don't suggest changing one on your own due to the fact that if you mess something up you could end up paying extra for someone to clean up your mess, or messing up the cam timing and crushing a valve or worse.



Pay someone to change it, depending on the vehicle, a broking timing belt while driving can DESTROY you upper half of the engine....
it would really help to know what kind of motor you are looking at, but as you have described it, It has got to be older, with multiple belts. most stock motors that I have ever seen have have timing belt covered, and would be on the same end of the engine block as the other belts that you are looking at. The timing belt is crucial to the motor operation, and I really don't mean to be rude but unless you have a second car to drive while you learn to find top dead center, my advice on this would be as follows: if you have to ask where it is, then you're better off taking it somewhere to have this belt replaced. Also the timing belt will usually outlive the other belts tenfold, If the car runs reliably then just change the belts that you can see, and enjoy the ride
the belts that are visible are V or fanbelts, the cambelt will not be visible, however more info is required, ie:;make, model %26amp; year.
those are your accessory belts. the timing belt should be behind a cover.if the teeth are worn and the belt has heat cracks then yes it should be replaced before it leaves you sitting.
the timing belt is normally covered. it is usually located near the other belts and pulleys
