Gates DriveAlign Serpentine Belt Tensioner

The Gates DriveAlign serpentine belt tensioner (also called a drive belt tensioner or automatic belt tensioner) keeps the correct tension on your engine's serpentine belt. It helps the belt drive the alternator, power steering pump, water pump, and air conditioning compressor reliably. Gates is an original equipment supplier known for engineered belt drive components, and the DriveAlign line is built to restore factory-level performance.

Key Features:

• Maintains proper belt tension automatically to reduce slippage, noise, and premature belt wear
• Engineered spring and damping mechanism to control belt movement and absorb vibration
• Durable housing and pulley construction designed for long service life under heat and load
• Sealed, precision bearing in the pulley for smooth, quiet operation
• Quality control testing to meet or exceed OE fit and function

A worn tensioner can cause belt squeal, chatter, uneven belt wear, and accessory drive problems. Replacing it along with a new serpentine belt and inspecting the idler pulleys is a recommended practice for dependable accessory drive operation. Select the correct part number for your application from the available variants.
