Failure Symptoms

A worn idler pulley may initially produce a faint squealing or grinding noise from the engine's front end. If ignored, the bearing can seize, causing the belt to slip or break, leading to a rapid loss of function for the alternator, water pump, and other driven accessories. This can result in engine overheating and a loss of power.

Installation Tip

When removing the old pulley, ensure the mounting bolt threads are clean and free of debris. Do not overtighten the new pulley's mounting bolt, as this can damage the bearing or the threads.

Service Note

Inspect the drive belt for cracks, fraying, or glazing, and check the tensioner arm for proper operation.
