Hi Alex,

They are a pain the first time. There is a deceptively easy trick to it. I wrote out the step by step for taking it off / putting it on.

Hope you find it helpful

Hi. look carefully under the hood as there is usually a sticker showing this. Also, look in the owner manual. If all else fails go to any NAPA store and ask them for a copy of the diagram from their database. J.

There is an idler pulley close to the power steering. Loosen the bolt that goes through the front of the idler pulley first. Then you will see the head of a bolt looking up at you. Turn the bolt clockwise to tighten and counterclockwise to loosen. The pulley is attached to the threaded bolt and it moves the pulley up or down as needed to adjust the belt tension. When the belt is replaced turn the bolt until the belt is tight. Remember to check the belt again after a few hundred miles. A new belt will stretch and loosen.
