I installed the Steeda pulleys. Although, I had the luxury of fully-equipmed shop at work. You're going to need an impact wrench to get the pulley bolt off the alternator. In order to get the crank pulley off, we created a "jam bar" that secured itself into the original pulley's spokes, and had a bar that settled onto the floor and stopped the crank from turning. With a pipe over a socket wrench for leverage, it was a piece of cake after that. The only problem is finding the correct size sockets. I believe we needed a 10mm and a 15mm. As far as the torque, we ahd a 3/4" wrench, but no 15mm socket for it. the Steeda pulleys are made of steel, so we used the old American way = Good-n-tite. Once we figured we needed to design a jam bar to stop the crank, which we welded together from scrap metal, it took about 20 minutes. Steeda is the only pulley system that is not a piggy back. Plus they're steel. They are the best. Good luck.
