Parts for your 2017 Honda Accord-Drive belt tensioner

2017 Honda Accord drive-belt tensioner — what’s fitted and what’s not

Yes, a drive-belt (serpentine belt) automatic tensioner is fitted on 2017 Honda Accord petrol models — both the 2.4L inline‑four and 3.5L V6 use one to keep the accessory belt at the right tension. On the 2017 Accord Hybrid, there’s no conventional accessory drive belt, so there’s no drive-belt tensioner on that variant.
