Dayco Automatic Serpentine Belt Tensioner Assembly

The Dayco Automatic Serpentine Belt Tensioner Assembly is a drive belt tensioner. It keeps the correct tension on the serpentine belt so the engine's accessory drive runs reliably. The accessory drive powers components such as the alternator, power steering pump, water pump and A/C compressor. Dayco is a well-known name in belt drive systems and supplies both OE and aftermarket markets.

Key Features:

• Automatic tensioning applies steady, spring-loaded force to the belt. It adjusts as the belt wears and stretches, so no manual adjustment is needed.
• The assembly is a complete tensioner unit, which makes replacement straightforward.
• The design helps limit belt slip, squealing, vibration and premature belt wear.
• It is built to meet the demands of modern accessory drive systems, including heat and constant load cycling.
• Dayco builds its parts to OE-style form, fit and function.

Benefits:

• Smoother, quieter belt operation
• Reliable power delivery to engine accessories
• Longer serpentine belt life

Replace the tensioner when you install a new serpentine belt. A worn tensioner can cause noise, belt wear and accessory problems. Choose the correct variant for your application from the options in this product line.
