What It Helps Address

• Squealing or chirping from a worn accessory drive pulley
• Belt tracking issues caused by pulley wear or surface damage
• Accessory drive noise from a rough or contaminated idler bearing
• Reduced belt stability in Nissan Frontier, TITAN, Armada, and Pathfinder applications
• Service replacement needs on INFINITI QX56 and QX80 accessory drive systems

Installation Notes and Tips

Verify pulley style, groove profile, and mounting dimensions against the original part before installation. Inspect the accessory drive belt, tensioner, and adjacent pulleys for wear so the new idler pulley is not installed into a compromised belt system. Confirm the application by year, make, model, and accessory drive position for Nissan and INFINITI vehicles listed above.

Quality Assurance

Continental builds this idler pulley to OE material standards and performance targets, with an anti-contamination shield designed to support long service life in the accessory drive system.
