You always want your Nissan to run like a well-oiled machine. Sure, you like using all the latest technology and features that make your driving experience fun and effortless. But under the hood, your Nissan still runs thanks to simple machines, like pulley and belt systems.

Your Nissan Accessory Drive Belt Idler Pulley is vital for efficient engine operation, and should be removed and replaced immediately if it is cracked, old, or absent. While this tucked-away part may not seem important, a worn out Accessory Drive Belt Idler Pulley could cause further damage to the engine’s bracket mountings or drive belts. If your Nissan has exhibited signs of diminished engine performance in recent days, visit your local Nissan-authorized service center to find out if a component of your engine’s belt system, whether it’s the Accessory Drive Belt Idler Pulley or something else, could be causing a problem.
