Belt Tensioner Pulley Assembly No.30711320 for Volvo C30 2008 Serpentine Tensioner

Feature of Belt Tensioner w/ Pulley: Replace the old or broken belt tensioner to avoid noisy tensioner pulleys and no longer withstand belt noise. Achieve proper belt tension, and alignment, and ensure the good performance. Torsional round spring provides reliability and consistent tension. Take the tension off and pull the pin out after getting the belt in position. The tension force is automatically adjusted to make the transmission system stable due to the different tightness of the belt. Solid metal for wear resistance, not easy to break or deform, ensures longer service life. Please allow slight dimension differences due to different manual measurements. This is a non-OEM product, accessory only!
