VAICO Accessory Drive Belt Tensioner Assembly

The VAICO Accessory Drive Belt Tensioner Assembly (also called a serpentine belt tensioner or drive belt tensioner) keeps the correct tension on the accessory drive belt. A properly tensioned belt reliably drives the alternator, power steering pump, water pump and air conditioning compressor.

Key Features:

• Maintains consistent belt tension across the operating range to reduce belt slip, squealing and premature belt wear
• Supplied as a complete assembly, so the tensioner body, spring mechanism and pulley are matched and ready to install
• Made to meet or exceed original equipment specifications for fit, form and function
• Designed to damp belt vibration and help keep the accessory drive running quietly and smoothly
• Made by VAICO, a brand of the Vaico/Vieroth group that specializes in replacement parts for European vehicles

A worn tensioner can cause belt noise, belt flutter, a loose belt, or failure of the accessories the belt drives. Replacing the tensioner when you replace the belt helps restore proper belt operation and protects the other drive components.
