Shopping for Accessory Belt Tensioner

Accessory Belt Tensioner Shopping Info

What Is an Accessory Belt Tensioner?

Different car mechanisms, such as your air conditioning or power steering, use belts to help them operate. Your accessory belt tensioner works by adjusting the tension of these belts so that your car’s accessories can function properly.

How Much Does an Accessory Belt Tensioner Replacement Cost?

Accessory belt tensioners usually cost between $10 and $90. Multiple factors can affect part pricing, such as inclusions, or the year, make, and model of the vehicle it’s for. Labor costs to replace your accessory belt tensioner may range from $80 to $100, depending on your location and vehicle model.
