URO Drive Belt Tensioner Assembly

The URO Drive Belt Tensioner Assembly (also called a serpentine belt tensioner or accessory drive belt tensioner) keeps the correct tension on the engine's drive belt. This helps the alternator, power steering pump, water pump and A/C compressor turn reliably. URO supplies replacement parts for European and import vehicles. This tensioner line is made to restore original belt tension and quiet, smooth operation.

Key Features:

• Replacement tensioner assembly that keeps the drive belt at the correct tension
• Helps prevent belt slip, squealing, chatter and premature belt wear
• Spring-loaded design absorbs belt vibration and compensates for belt stretch
• Built-in pulley with a bearing for smooth rotation
• Designed as a direct-fit replacement for the original equipment part

Why Replace It: Over time, tensioner springs weaken and pulley bearings wear. This can cause belt noise, a wobbling belt, accessory failure or a belt that comes off. Replacing the tensioner when you install a new drive belt helps keep the whole accessory drive system working properly.
