The operation of a toothed belt involves the interaction of these teeth with the grooves on the pulleys. When the driving pulley rotates, the belt moves in unison, causing the driven pulley to rotate at a specific ratio, which is determined by the size of the pulleys and the number of teeth on the belt. This precise coordination allows for accurate synchronization in applications like engine timing, where even a slight delay can result in serious mechanical issues.

Timing belts typically have a lifespan of about 60,000 to 100,000 miles, depending on the make and model of the vehicle, as well as driving conditions. Regular maintenance and timely replacement of the timing belt are essential to avoid significant mechanical failures. Many vehicle manufacturers recommend replacing the timing belt as part of routine maintenance, often during the ten-year or 100,000-mile service interval.
