Quick facts

Part: INA US FT40568 belt tensioner
Also called: serpentine belt tensioner
Fits: 2006-2010 Infiniti M45 V8 4.5L and other vehicles

A squealing belt, belt flutter or uneven belt wear can mean the tensioner no longer holds tension. Before replacing it, look over the belt and pulleys with the engine off for cracks, glazing or a rough pulley, since a worn belt or another pulley may be behind the noise.
