Detailed Description

Gates 36336 is a DriveAlign Premium OE Pulley engineered for accessory drive belt systems that use a smooth idler surface rather than a grooved pulley. It is specified for select INFINITI FX35, M35, G35, QX4 and Nissan 350Z and Pathfinder applications where the pulley supports alternator and power steering belt routing. The steel body, 84 mm outside diameter, and 12 mm bearing bore help match OE-style dimensions for proper belt tracking and pulley alignment.

This part cross-references Dayco 89150 for the same application.

What It Helps Address

• Belt noise from a worn idler pulley
• Rough pulley rotation caused by bearing wear
• Serpentine belt tracking issues
• Accessory drive belt vibration
• Loss of proper belt routing support in alternator and power steering systems

Installation Notes and Tips

Verify pulley diameter, bearing bore, and contact surface before installation. Confirm the vehicle’s belt routing and pulley position against the original part, especially on 2003-2008 INFINITI FX35, 2006-2008 INFINITI M35, 2003-2007 INFINITI G35, 2003-2006 Nissan 350Z, 2001-2004 Nissan Pathfinder, and 2001-2003 INFINITI QX4 applications. Inspect the belt, tensioner, and adjacent pulleys for wear during service to help prevent repeat failure.
