ACDelco GM Original Equipment Drive Belt Tensioner Assembly

The ACDelco GM Original Equipment Drive Belt Tensioner Assembly line includes serpentine belt tensioners, also called automatic belt tensioners or drive belt tension pulley assemblies. They are designed to keep the correct tension on the accessory drive belt. That helps the alternator, power steering pump, water pump and air conditioning compressor run reliably.

Key Features:

• GM Original Equipment design, built to meet GM specifications for fit, function and durability
• Spring-loaded tensioner assembly that automatically compensates for belt stretch and wear
• Integrated pulley that guides the belt smoothly and quietly
• Helps reduce belt slip, squealing, vibration and premature belt wear
• Backed by the ACDelco brand, GM's parts brand

Replacing a worn tensioner along with the drive belt helps restore quiet, dependable accessory drive operation. Choose the specific part number from the options on this page.
