Dorman Automatic Belt Tensioner Assembly with Smooth Pulley

The Dorman Automatic Belt Tensioner Assembly with Smooth Pulley (also called a drive belt tensioner or serpentine belt tensioner) keeps the right tension on the accessory drive belt. This helps the belt drive the alternator, power steering pump, water pump, and A/C compressor reliably. Replacing a worn tensioner helps stop belt slip, squealing, and uneven belt wear.

Key Features:

• Complete assembly with an integrated smooth pulley that guides the belt
• Automatic, spring-loaded design that keeps belt tension correct as the belt wears and as engine load changes
• Designed to replace the original tensioner and restore proper belt operation
• Helps cut down on belt noise, vibration, and belt slippage
• Backed by Dorman's aftermarket engineering and quality standards

Benefits: A failing tensioner can cause chirping or rattling noises, a wobbling pulley, premature belt wear, or loss of accessory function. Installing a new tensioner assembly restores smooth, quiet belt operation. It's best to inspect the belt and idler pulleys at the same time and replace them if they show wear.
