my car is reaching 100,000 miles and im beening told bye my mechanic that i should replace timing belt,that it is maintance for car, it is quite costly so i need more opinions %26quot;please%26quot;.......thank you so much much for those who give me advise.

Well it may be true. Depends on the car that you drive. This is where information like year, make, model, engine would be helpful to answer questions. So I am going to have to guess at what you drive and I pick that you are driving a pre 1985 Volvo and you should have replaced your belt already at the 40,000 mile and again at the 80,000 mile marks. So by this interval you will need to replace again at the 120,000 mark. Now if I picked that you drive a 1999-2004 Ford with a 2.0L DOHC engine then you would not need to change it until the 120,000 mark. Or you could drive a Subaru with a 1.8L engine, in which case you would have changed it at 52,000 miles and it will be needed again at 104,000 miles.

most cars with timing belts should be changed at about 60 to 70 thousand. it's called required maintanance because an old worn belt can break and that can result in some serious expensive damage to the rest of your engine. an ounce of prevention is worth a pound of cure.
Have an owners manual. --if you read it , - and it is really a belt, -( and not a %26quot;chain%26quot;), - you will find you are probably way overdue! Belts are considrably easier to change than timing chains!



As for timing chain, it makes a whole lot of difference what kind of engine it is, and how well you take care of oil chance sechedules! Also what brand/quality oil used! Also how hard you drive (or mistreat it)!! Timing chains %26quot;run in oil%26quot; which makes them last a long time, if the oil is clean, and changed regularly! Mechanic can tell to a large degree how timing chain is doing,- by putting on a timing light, and seeing how well the ignition times to the %26quot;marks on engine, - if chain worn and %26quot;stretched, - it will not run right when set properly with marks, - will require advancing timing to some degree in order to minimize power loss!---- you may want an %26quot;oldtimer%26quot; to check this,--- new %26quot;computer operators%26quot; may not understand this concept%26quot;!



To change timing chain requires removing front %26quot;harmonic balancer%26quot; (or %26quot;vibration damper%26quot; they call it now)- remove all %26quot;bolt on%26quot; stuff in front of timing chain cover (on most engines the waterpump is located in front of timing chain cover)--, and take it off to replace chain (and probably gears), - if main one is plastic!



But then again you may be needing it more closer to 150-175K anyway!
It is different for different vehicles. You should consult your owners manual or, if you can't find that, call you local dealership and ask them what the recommended life span of the timing belt is for your year\engine\model. Timing belts usually don't last as long as Timing chains so 100k does sound about right. And yes it is pretty expensive on a lot of vehicles because all the accessories have to be taken off to get to it.
on some vehicles the timing needs to be replaced at 60k. not knowing what kind of vehicle that you have, i must trust your mechanic's recommendation. on most cars if a timing belt breaks the engine suffers quite a bit of damage to valves and possibly pistons. take care of your vehicles needs. have it replaced
