I just installed my new fluidampr on the truck last nite(finally) I had to cheat I couldn't get the fan to break free, so it took me, my neighbor, and my nephew, but I slipped it on without the fan being off. Had to guess at the 60 deg extra past the 30 ft lbs torque on balancer bolts, my snap-on degree indicator was too big with the fan on. First impression was a lot quieter idle, smoother acceleration, so far I like it, I was just trying to see if anyone else has any feedback on this, thanks
