Gates DriveAlign Heavy Duty Automatic Belt Tensioner

The Gates DriveAlign Heavy Duty Automatic Belt Tensioner (also called a drive belt tensioner or serpentine belt tensioner) keeps the right tension on the accessory drive belt. This helps the alternator, water pump, power steering pump and A/C compressor run reliably. Gates is a global leader in original equipment system design. DriveAlign tensioners are built to OE-grade standards for fit, form and function.

Key Features:

• Patented damper: Reduces tensioner motion and vibration. It is designed to extend the life of both the belt and the tensioner.
• Round spring design: Gates uses a patented round spring that resists contamination better than a flat spring design. Its chrome-silicone coils do not rub against each other, so operation stays quiet and the spring is less prone to flex fatigue.
• Unique sealing: Protects the internal parts from contamination to support durability and service life.
• OE-quality manufacturing: Made to tight tolerances and specifications to match original equipment form, fit and function.

Replacing a worn tensioner at the same time as the belt helps prevent belt slip, squealing, premature belt wear and accessory drive noise. It also helps keep the accessory drive running smoothly for the long term.
