Hey thanks for the help. But I don't want you or anyone to thing that I not familar with that. I have tried the advance search and there are things on tensioner but not related to my problem.

the problem began with all my belts being loose to the point that i can slip them off with ease. i guess to rephrase the question, " to tighten my belt what do i do" cause i haven't found any information on this. the best info i have come across is having to do with the tensioner assembly. and when i go back to the car i'm able to move the pulley from left to the right. if i hold it to the right it tightens my belts. is there a way to tighten the assembly or does this mean i need a whole new assembly. ANYBODY
