Accessory Drive Belt Tensioner
Volvo

The accessory drive belt tensioner maintains proper tension on the serpentine or accessory belts, ensuring smooth operation of auxiliary components such as the alternator, power steering pump, and air conditioning compressor. Its spring-loaded mechanism automatically adjusts to compensate for belt wear and elongation, preventing slippage or premature failure. Proper tensioning reduces noise, vibration, and the risk of belt breakage, which can lead to costly downtime. This component is engineered for durability, resisting the stresses of high-speed rotation and temperature fluctuations. Regular inspection and replacement of the tensioner are critical for maintaining the overall health of the accessory drive system. Source One Parts Center offers this high-quality tensioner to support your vehicle’s reliable operation and minimize maintenance costs.
