The ACDelco manual accessory belt tensioner maintains correct serpentine belt tension on the Honda Accord accessory drive. Sealed bearing with preloaded spring delivers consistent tension across the full belt life. Replacing the tensioner together with a new belt prevents the documented failure mode where a worn tensioner ejects the new belt within weeks.

Fits: 2000-2024 Honda Accord (all engine variants).
