ACDelco Flanged Drive Belt Idler Pulley

The ACDelco Flanged Drive Belt Idler Pulley guides and maintains proper routing of the serpentine or accessory drive belt. It is also sold as a drive belt idler pulley or serpentine belt idler. The flanged design helps keep the belt centered on the pulley during operation, which supports smooth, quiet belt travel.

Key Features:

• Flanged design helps keep the drive belt aligned and tracking on the pulley
• Sealed bearing construction supports smooth, low-noise rotation
• Replaces worn or noisy idler pulleys to help restore proper belt routing
• Backed by ACDelco, a trusted name in replacement automotive parts

A worn idler pulley can cause belt squeal, vibration, premature belt wear, or belt slippage. Replacing it with a quality ACDelco pulley helps restore reliable accessory drive performance. It is best to inspect the belt and tensioner at the same time and replace them as needed.
