Dayco 89600 belt tensioner for the 2006-2015 Honda Civic 4-cylinder 1.8L and other vehicles holds the accessory drive belt at the right tension. Some catalogs list it as a serpentine belt tensioner; it is one assembly with a single pulley.
A squealing or slipping belt, or one that flutters, can mean the tensioner has worn out. These signs alone do not prove the tensioner is the problem, since a stretched or glazed belt is another common cause. If the tensioner is at fault, this assembly replaces it.
This belt tensioner for the 2006-2015 Honda Civic 4-cylinder 1.8L also fits the 2016-2022 Honda HR-V and the 2013-2015 Acura ILX 4-cylinder 2.0L. Every one of them needs a single tensioner.
