    Tensioner failed on my truck and I can't get Allen bolt holding it on. Is it reverse tread?

    I've had to replace many of those accessory bracket on that engine over that stupid Allen bolt. If it's not seized/corroded in the tensioner the threads are locked and it strips the head.

    If its fighting you replace the whole bracket, its actually priced reasonably if I remember correct.
