Some things tend to be taken for granted. We take it for granted that if a timing belt is left on an engine long enough, it will eventually break. That’s why we encourage our customers to change their timing belts either at or before the manufacturer’s recommended interval. We know that if they don’t follow our recommendations, sooner or later the customer will end up stranded at the side of the road with a broken timing belt. Depending on the configuration of the engine, this may or may not also result in some pretty serious additional engine damage.
