ACDelco Professional Serpentine Drive Belt Tensioner Kit

The ACDelco Professional Serpentine Drive Belt Tensioner Kit is a replacement belt tensioner kit for the serpentine (accessory) drive system. The tensioner keeps the proper tension on the serpentine belt. That tension lets the belt reliably drive accessories such as the alternator, power steering pump, water pump and air conditioning compressor. Many of these kits are also sold as a drive belt tensioner assembly or an automatic belt tensioner kit.

Key Features:

• Designed to restore correct belt tension and help limit belt slip, noise and premature belt wear
• Part of the ACDelco Professional line, which is built to meet or exceed the needs of professional repair shops and demanding daily drivers
• Backed by ACDelco, General Motors' parts brand, and engineered for dependable performance and a long service life
• Intended to be installed with a new serpentine belt as part of a complete drive system refresh

Replacing a worn tensioner can help prevent squealing, belt jumping and accessory failure. Choose the kit that matches your application's part number for a dependable repair.
