Bolt holding serpentine tensioner to engine block on 1996 Buick Century

I need to replace serpentine tensioner in my daughters car. The tensioner fell apart completely. It will be nessasary to remove the tensioner from the engine block and replace. Is that center bolt left hand thread or does it remove as normal (counter clockwise)?

Here are some good repair manual sites: I think that Alldata has the best remove and replace instructions.
