If your not going to explain or give anymore info on why it took 6 hours to replace the belt(did you match the belt up old to new?) and what happened when it quit(belt broke- dash lights that went on- still cranked over Etc. Etc...)I'm not sure anyone here can help...Just looking at mine if you have AC the tensioner looks hard to get at so I would have just loosened up the alternator(which is right in front, easy to get at) and eased the belt on, then tightened the alternator back up....Only explanation is you threaded the belt on wrong

...How did you get it off, cut it
