💡 Why do timing belts require specific maintenance intervals compared to others?

An effective tensioner keeps the belt at optimal tension to prevent failure.
- Older units lose spring force allowing excessive belt movement over time
- New units restore factory preload settings for reliable durability and run
- Proper sizing prevents premature wear on driven engine components quickly
