What a Bad Belt Tensioner May Look Like. This is the second Dayco No Slack belt tensioner I have put on this car. The first one lasted maybe 2 months, and the current one was bad straight out of the box. You can see the tensioner pulley wobbles back and forth, and makes the belt wobble also.
UPDATE: Well today I turned the wheel and heard a loud bang followed by a lose of power steering and a battery light. I pulled over and check and the alternator bracket snapped right off! So maybe it was cracked all along and the belt was out of alignment...?
