Re: Need some help removing tensioner assembly!
Here is a copy from my post on someone else who asked this question just a few weeks ago. You may be turning the bolt the wrong way. Some are reverse thread.
Easiest way to check which way the bolt will come out. Mark a white line on the serpentine belt with chalk. Start the car and note the direction of chalk line travel on the belt.
If the belt is traveling clockwise:
pulley above the belt- counter-clockwise thread
pulley below the belt- clockwise thread
If the belt is traveling counter-clockwise:
pulley above the belt: clockwise thread
pulley below the belt: counter-clockwise thread
If someone finds me wrong- please chime in. This has worked for me so far.
