Failure Symptoms

A failing belt tensioner will often first produce an audible squealing or chirping sound from the engine bay, especially on startup or acceleration. If the tensioner loses its ability to maintain tension, the drive belt may slip, leading to intermittent issues with charging, cooling, or power steering.

Installation Tip

Ensure the mounting surfaces are clean and that the new tensioner pivots freely before installation. Do not use excessive force when compressing the tensioner to install the belt.

Service Note

Always replace the serpentine drive belt when replacing the belt tensioner.
