Gates DriveAlign Automatic Belt Drive Tensioner

The Gates DriveAlign Automatic Belt Drive Tensioner keeps the correct tension on a serpentine or accessory drive belt. It is also called a belt tensioner or drive belt tensioner. It helps the belt drive the alternator, power steering pump, water pump and A/C compressor reliably.

Key Features:

• Automatic spring-loaded design keeps belt tension consistent as the belt wears and as engine load and temperature change
• Built as a complete tensioner assembly, with the spring mechanism, pulley and mounting hardware integrated into one unit
• Engineered to match the original equipment tensioner's form, fit and function
• Helps limit belt slip, noise, vibration and premature belt wear
• Made by Gates, a long-established maker of belts, hoses and belt drive components

Replacing a worn tensioner along with the drive belt helps restore smooth accessory drive operation and gives the new belt a longer service life. Common signs of a failing tensioner include belt squeal, a chattering or wobbling belt, uneven belt wear and a noisy pulley bearing.
