Gates DriveAlign Belt Drive Idler/Tensioner Pulley

The Gates DriveAlign Belt Drive Idler/Tensioner Pulley line provides replacement idler pulleys and tensioner pulleys for serpentine and V-ribbed accessory drive systems. These pulleys guide the drive belt and help keep it tensioned and aligned. This supports reliable operation of the alternator, power steering pump, water pump, and A/C compressor.

Key Features:

• Designed for use as a drive belt idler pulley or tensioner pulley, depending on the application
• Sealed bearing construction helps keep out contaminants and retain lubrication for long service life
• Precision-manufactured pulley surfaces help the belt track smoothly and run quietly
• Built to meet or exceed OE performance requirements
• Backed by Gates, a respected name in belts, hoses, and belt drive components

A worn idler or tensioner pulley can cause belt noise, belt wear, vibration, or belt slip. Replacing it along with the drive belt helps restore proper belt alignment and tension. Choose the correct part number for your application from the options listed on this page.
