I would buy the set so you make sure you get the right size. Use them and clean them up and return them and say they wouldnt work and get your money back.

They may not be bolts, might be the allen wrench type, on the back side of the calipars, one on top and one on the bottom. Not sure what size.

There should be a square slot for a 3/8" drive ratchet to fit in. that is where you grab the tensioner to pull it to the side for belt removal. The normal tool for this is a long flat bar with the square end so you can get enough leverage. If there is enough room a 1/2 drive breaker bar with a 1/2 to 3/8 adaptor will work.

I relaces my alternator and now my tention pully is slanted enough where my belt keeps slipping off. Is there a bolt I missed, cause i cant find one?

Most likely, tensioner is worn out and needs to be replaced.

I believe one bolt through the center of it holds it to the motor. Be aware that this bolt may have left handed threads so it would have to be turned clockwise to loosen if this is the case.
