i finally got it off talked to dealership and they told me what the usually do is heat the crank pully bolt till it is cherry red then go from there and i heated it for awhile till cherry red and finally with a breaker bar and a 3ft pipe on it yes that much leverage lol it broke loose and did not damage anything else def a bitch of a job but i got it done after three days of trying everything known to mind i was afraid to heat it that much but dealer said it would be fine and it was thanks for the help tho guys
