Which Is Better Timing Belt or Chain?

A: Timing chains are stronger than timing belts. Timing chains also last longer. Timing belts are quieter than timing chains and are cheaper and easier to replace.

Why are timing belts used instead of chains?

Auto manufacturers started using timing belts because they are much less expensive to manufacture and they run more quietly. Timing belts usually have rubber “teeth”: Most normal car users (not hotrod racers or performance car people) tend to prefer quieter cars. Timing belts run much more smoothly than a timing chain.

Do timing chains last forever?

A: As a general rule, if an engine has a timing chain and the oil was changed on a regular basis, the timing chain should last the lifetime of the engine.
