Belt Adjustment: Notes

WARNING: This page is about a different variant/trim than selected.

Inspect belt for fraying. If fraying has occurred, ensure belt and tensioner are aligned properly. See Fig 1. If tensioner has reached its limit of travel, belt is excessively stretched and replacement of belt is required. See Figure-Figure . If excessive noise is noticed from tensioner or idler, check for possible bearing failure. Belt tension adjustment is not required on vehicles with automatic belt tensioners. DO NOT apply belt dressing or any other additive to belt(s). Ensure belts are properly installed. See Figure- Figure . See BELT TENSION ADJUSTMENT SPECIFICATIONS table.
