ACDelco Professional Drive Belt Tensioner Assembly

The ACDelco Professional Drive Belt Tensioner Assembly (also called a serpentine belt tensioner or automatic belt tensioner) keeps the proper tension on the accessory drive belt. Correct belt tension lets the alternator, power steering pump, water pump and air conditioning compressor run reliably.

Key Features:

• Maintains consistent belt tension to reduce belt slip, squeal and premature belt wear
• Assembly design combines the tensioner mechanism and pulley in one unit
• Engineered for dependable operation and long service life under demanding underhood conditions
• Part of the ACDelco Professional line, which is built to meet or exceed fit, form and function expectations
• Backed by the ACDelco brand, a longtime supplier of parts developed with GM engineering know-how

A worn tensioner can cause noise, belt flutter, accessory problems or belt failure. Replacing it with a quality assembly helps restore smooth, quiet drive belt performance. Replace the drive belt at the same time, since the two components wear together. Select the specific part number in this product line for your application.
