Yeah, that thought crossed my mind if I could get my impact gun to fit up in there. The install directions said not to turn the engine counter clock wise so I was a little worried about trying that. I will probably call Renntech Monday to double check about the bolt threads and ask how or what they do to hold the flywheel. The inspection cover hole is very small and hard to see what to get hold of. The install directions said to tighten the new pulley to 200 Nm + 90 degrees, the tech that I talked to Friday told me that 200 Nm was around 155 foot pounds then turn the bolt another quarter turn. My 1/2" drive torque wrench tops out at 150 Fp, so I know that bolt will be tight as hell, I just don't want to screw anything up. So in the meantime I'll probably do some cleaning things up on the bottom side while the car is raised up. Thanks for the input Iamfink2, I was hopping that HDDP would see this thread since he's been into racing I figured he may have removed a pulley from one of these Crossfires.
