Recently, my alternator bearings froze up. When I went to change it I found that the belt tensioner was also froze up and the belt was extremely tight (I think that might have been the reason the alternator bearings burned up.) I went to remove the tensioner. I removed the large bolt at the center of the pivot point no problem. The second bolt was very hard to crack loose, but I got it. Now it threaded out and I can pull it loose about 1-1/2 inches and then it is stuck. ??? This bolt will turn until I try to pull it out. Once it jams, it is also very hard to turn. I have no idea WTH is going on and am wondering if I am going to have to remove my oil filter bracket now (it seems that the bolts for the tensioner go through the bracket and thread into the engine block underneath the bracket. My worst fear is the the threads stripped out of the engine block and are stuck on the bolt and that is what is keeping it from coming out all the way. Any ideas?
