Dayco Timing Belt Idler Pulley

The Dayco Timing Belt Idler Pulley (also called a timing belt roller or timing belt tensioner idler) guides the timing belt along its path and keeps it correctly aligned. It helps maintain proper belt contact and tension so the camshaft and crankshaft stay in sync.

Key Features:

• Engineered as a replacement for the original idler pulley in timing belt systems
• Precision-made bearing for smooth, quiet rotation
• Durable pulley construction built to handle heat, load and long service intervals
• Helps reduce belt wear, noise and the risk of premature belt failure
• Made by Dayco, a long-established supplier of belt drive components to the automotive aftermarket

Replacing the idler pulley at the same time as the timing belt is a common practice. Doing so helps restore dependable valve timing and protects the engine. Choose the specific part number that matches your application from the options listed on this page.
