Hey guys, I am in the process of getting my truck running again. When my vacuum pump went out my belt tensioner pulley mostly melted too...so I need to replace that pulley. I took the whole tensioner off last night and tried removing the bolt holding the pulley with my impact wrench...it would not budge. Is this bolt reverse threaded? What am I doing wrong? I have the serpentine belt tensioner that has the spring inside of the body if that makes a difference. Thanks for any help.
