The spring applies constant pressure to the idler pulley to maintain correct timing belt tension. A weak, broken, or missing spring causes belt slack, timing deviation, and can lead to catastrophic engine damage.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e This spring is for \u003cstrong\u003espring-type tensioner\u003c\/strong\u003e models only.
