Tensioner for timing belt in original position.
 

I was changing the timing belt and didn't know I had to put a pin in it to hold the bolt from going into its original position. My question is, how do I get it back in position to put tension on the timing belt?

Do you see the bolt in the center of the tensioner? I loosen it, pry it out of the way and then tighten it back down to change the belt. After the belt is changed, all one does is loosen the bolt, allow it to snap into position, and snug it down.

Thanks! I eventually figured it out. Spent 12 hours in 2 days replacing the timing let and when I put it back together and try to start it, it idles and dies. Obviously I didnt line the notches up right so I gotta tear it apart and try again :( this is my first time ever working on a car.
