Product Details

Gates DriveAlign pulleys are engineered to match OE fit and function in accessory drive belt systems. This 36313 pulley is used as an idler pulley and can also serve in OE-style tensioning layouts where a smooth pulley is required. The design supports proper belt tracking on the backside of the belt, making it a practical replacement for worn pulleys in Chrysler, Dodge, Ram, Jeep, Suzuki, and Volkswagen applications.

This part cross-references Continental 49161 and Dayco 89361 for the same application. The Gates 36313 is a relevant replacement when servicing belt noise, pulley wear, or belt routing concerns on vehicles such as the Dodge Charger, Chrysler 300, and Jeep Grand Cherokee.

Common Issues This Part Can Address

• Squealing or chirping from a worn idler pulley
• Belt tracking problems on smooth/backside routing
• Rough pulley rotation caused by bearing wear
• Accessory drive belt vibration or noise
• Visible pulley surface wear or cracking

Installation Notes and Tips

Verify pulley diameter, bearing bore, and belt contact style before installation. Confirm the vehicle’s belt routing and compare the original pulley to the Gates 36313, especially on Chrysler 300, Dodge Charger, Ram 1500, and Jeep Grand Cherokee applications. Inspect the serpentine belt, tensioner, and adjacent pulleys at the same time so the new idler pulley is not installed into a worn system.
