Goodyear Belts & Hoses 55208 Automatic Belt Tensioner Assembly

The Goodyear Belts & Hoses 55208 Automatic Belt Tensioner (also called an accessory drive belt tensioner assembly or serpentine belt tensioner) keeps the right amount of tension on your engine's belt drive. It adjusts continuously as operating conditions change, which helps the belt drive run efficiently.

Key Features:

• Automatic tensioning mechanism that adjusts belt tension as needed under varying operating conditions
• Pulley outside diameter of 74 mm (2.91 in)
• Item width of 46.3 mm (1.82 in)
• Precision-made pulley for proper belt alignment
• Dampens torsional vibrations to help extend belt life
• Built with durable materials and low-friction bearing technology to reduce wear, noise, and vibration

A tensioner with worn bearings or weak spring force can cause belt slip, noise, and uneven wear. Replacing it helps restore belt drive performance and supports accessories such as the alternator, power steering pump, and A/C compressor. Goodyear Belts designs its tensioner line to meet or exceed OEM specifications.
