Pulley bearing wear
Appearance: With the engine off and the belt removed, manually rotate the pulley. If you notice noise, resistance or roughness, the problem is likely to be pulley bearing wear.

Cause: Defective bearing and/or pulley.

Pulley surface wear
Appearance: Flat and grooved surfaces should be smooth and free from chips, cracks and dents. The high points of the grooves should not be worn down and be of equal height. Plastic pulleys have fins in sidewalls that should not be cracked or broken.

Cause: Belt wearing into the pulley.

Rust bleed and cracks
Appearance: Rust is bleeding between arm and base or dripping from the tensioner. Also, check the tensioner for cracks or damage to arm, housing and bracket. Some damage can’t be seen unless the tensioner has been removed.

Cause: Rust bleeding or dripping is a sign of internal component wear. Most common crack damage occurs at tensioner “stops” and mounting
