Detailed Product Information

Gates 36113 is a single accessory drive belt idler pulley engineered to match OE dimensions and operating characteristics. The steel body, flanged design, and V-ribbed grooved contact surface support stable belt routing in the air conditioning drive position. This part is listed for 1996-2000 Nissan Pathfinder, Air Conditioning, and 1997-2000 INFINITI QX4, Air Conditioning. Gates 36113 also cross-references Dayco 89511 for the same application.

The DriveAlign Premium OE Pulley line focuses on OE-style replacement pulleys for accessory drive belt systems, including idler, tensioner, and locked-center applications where exact fit and consistent belt alignment matter.

Common Problems This Pulley Can Address

• Belt noise from a worn or rough idler pulley bearing
• Improper belt tracking caused by pulley wear or flange damage
• Accessory drive vibration related to pulley surface wear
• Air conditioning belt routing issues on the listed Nissan and INFINITI applications
• Reduced belt stability from an out-of-spec pulley diameter or bore

Installation Notes and Tips

Verify pulley diameter, groove count, bearing bore, and flange style against the original part before installation. Inspect the accessory drive belt, tensioner, and adjacent pulleys for wear at the same time, since a worn belt system can shorten the service life of the replacement pulley. Confirm the air conditioning drive application on 1996-2000 Nissan Pathfinder and 1997-2000 INFINITI QX4 before ordering Gates 36113.
