A timing belt, timing chain, or cambelt is a part of an internal combustion engine that synchronizes the rotation of the crankshaft and the camshaft(s) so that the engine’s valves open and close at the proper times during each cylinder’s intake and exhaust strokes.
Subsequently, How often does a timing chain need to be replaced?
between 80,000 and 120,000 miles

Is a timing chain better than a timing belt?
Most automakers recommend replacing the timing belt every 60,000 to 105,000 miles. Timing chains are heavier and more complex than timing belts, but they also last much longer. Really, unless there’s a problem, timing chains don’t have a replacement interval.
What does a bad timing belt tensioner sound like?
When the tensioner or tensioner pulley fails, the loss of tension can cause the belt and pulleys to make high-pitched rattling or chirping noises. If the pulley bearing completely fails, it can also cause a squealing or even a grinding noise. Symptom 2: Knocking or slapping.
When should a timing chain be replaced?
Every time you use the engine, the timing chain is in use. When does a timing chain need to be replaced? The timing chain normally needs to be replaced between 80,000 and 120,000 miles unless there is a specific problem. Issues with the chain are common in higher mileage vehicles.

Does a timing belt make noise before it breaks?
When the timing belt wears out, it can cause a ticking or clicking sound to emanate from the engine. … There is a tensioner that keeps the belt taut, and that tensioner is pressurized by the engine oil. If the tensioner has no oil pressure, the belt will become loose and possibly disengage from the pulleys and/or break.
Why do they use timing belts 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.
Does a timing chain last longer than a timing belt?

Can you drive with a bad timing belt tensioner?
”It is not safe to drive with a bad belt tensioner because the belt tensioner ensures sufficient tension to power the accessories. As the tensioner wears, the belt can slip at the accessories creating noise, excessive heat at the accessory pulleys, and reduce accessory performance.
How long will a timing chain last?
In a well-maintained engine, a timing chain can last up to 300,000 miles or even longer.
