    How do you all typically loosen tension on these? Should I hook a ratchet to the small bolt on the pulley that is off axis or do people typically hook a ratchet or something to the main axis for what provides the tension? I'm working on my wife's Isuzu and don't want to snap a bolt or anything

    Usually adjusts at the alternator. Loosen the pivot bolt first, then the bolt in the slotted hole. The alternator should rotate releasing the tension.

    Is the bolt that holds on the tensioner pulley reverse threaded or not?

    Not sure man. I think you should get a service manual for the vehicle you're working on.
