This pulley is a critical component of the engine's accessory drive system, responsible for guiding and tensioning the drive belt.

Failure Symptoms

A high-pitched squealing noise, especially on startup or under load, is the first sign of a worn pulley bearing. If ignored, the bearing can seize, causing the belt to slip, overheat, and potentially break, leading to a loss of power to critical accessories. Continued operation with a failing pulley risks damage to the belt and other accessory drive components.

Installation Tip

Ensure the mounting surface is clean and free of debris before installing the new pulley to prevent misalignment. Do not overtighten the mounting hardware, as this can damage the pulley bearing or shaft.

Service Note

Inspect the drive belt for wear and proper tension when replacing the pulley.
