Information
Drive belt deflection roller.
Also referred to as a relay roller or deflection roller, responsible for guiding and maintaining proper routing and tension of the accessory drive belt system.

The idler pulley supports the accessory drive belt, helping to:
• Maintain proper belt routing and tension, preventing slipping and reducing premature wear.
• Guide the belt around engine accessories such as the alternator, power steering pump, A/C compressor, and water pump.
• Ensure smooth operation of components driven by the belt for optimal engine performance.
If the idler pulley wears out or the bearing fails, you may hear squealing, chirping, or grinding noises, see uneven belt wear, or experience belt misalignment - indicators it’s time for replacement.
A worn or failing idler pulley can cause the drive belt to slip, misalign, or break, which can in turn disrupt power to critical engine accessories. Symptoms include belt noise, squealing, or loss of accessory function (e.g., A/C, alternator charging), potentially leading to more costly repairs if ignored. Replacing it with an OE Match pulley ensures proper belt tension and routing, helping keep your engine’s accessory systems functioning smoothly.
Replace the idler pulley if you notice any of the following:
• Squealing, chirping, or grinding noises from the belt area
• Visible belt misalignment or excessive wear
• Pulley bearing play or rough rotation to the touch
• Cracks or deterioration of the pulley surface
