Hello and Thank you for using JustAnswer.com
Here is how the tensioners work and the belt layout for you
clockwise on the adjuster when the center bolt is loose?
On the main belt, you need to crack the 14 mm nut loose on the center of the pulley. Just loose, and then you can turn the adjuster to loosen or tighten the belt
to pull it up?
Clock wise for the alternator belt
On the power steering it's reversed
Clock wise loosens the belt, while counter clock wise tightens
You may want to spray some WD40 on the threads of the adjuster, on some cars with age, that adjuster could build up some rust and be hard to turn. In some cases it can also break.
If you have any more questions on this, please feel free to ask. Thanks Jay!
