good to hear you got it off * now you know why mechanics charge so much, not because its hard but because when shit like this happens we get headache's * lol.
your also corrrect about the tensioner and its considerd good practice to replace all seals,bearings,studs,water pump etc.. i'd suggest this if you dont wana be pulling this shit appart again... other then that tehres the old rule, if it aint broke dont fix it. up to you
