A-Premium Belt Tensioner Assembly for Honda & Acura 2.4L — Direct-Fit, Sealed Bearing, Flanged Pulley

A-Premium's belt tensioner assembly with pulley is a direct-fit replacement designed to restore proper V-ribbed belt tension and smooth accessory drive operation on specified Honda and Acura 2.4L engines.

If your engine accessories are showing noise, belt slippage, or premature wear, the tensioner is often the root cause. This A-Premium unit swaps in for factory tensioners on select Honda Accord, Crosstour and Acura TSX models, matching OE mounting points and bearing dimensions to simplify installation and help the serpentine belt track correctly.

How will this tensioner affect engine noise and belt wear?

Replacing a worn tensioner can reduce squealing and vibration by maintaining consistent belt pressure and alignment. The assembly uses a single flanged pulley and sealed bearing designed to rotate quietly under load.

• Restores correct belt tension to reduce slipping and squeal
• Sealed bearing for smoother, quieter rotation
• Flanged pulley keeps V-ribbed belt centered on the groove
• Durable construction aimed at matching original equipment life
