Mustang Serpentine Belt Tensioner Assembly

About

A belt tensioner assembly is a device consisted of an idler pulley and other components to complete the assembly that provides tension to the belt. It is usually located in between the driven and driving pulleys. The belt rotates around the driving and driven pulleys at high speeds which makes it stretch. As time passes, the stretched belt will become loose and will reduce its friction against the pulleys. The belt tensioner assembly provides tension to the belt for it to obtain the amount of grip needed to drive the pulleys. A belt tensioner assembly can be adjusted to attain the correct pressure needed to drive the pulleys. Without a belt tensioner assembly, belts will have to be replaced more often to be able to drive the pulleys properly. Auto Parts Network offers a wide selection of parts for all your automotive needs. Hide
