How do I make it tighter???? I can't find a thing to adjust it... Please help.

 

The A/C belt has a tensioner pulley, which you have to move in order to tighten or loosen the belt. At the moment I can't remember how you move the pulley to adjust it, it's been almost a year since my A/C belt broke and I replaced it.

 

I see a little pulley but I don't know how to move it

 

there is a bolt....
turn in it....
to tighten .... the other way to loosen....
the bolt goes up and down.... the tensioner connected to a "nut"
