First off, if you haven't done this, be sure it unbolted from the intercooler. Remove 3 of the 4 bolts from the SC top and leave the 4th almost all the way out so that its loose.
Then, unbolt the washer fluid reservoir from the frame. Back the nut almost all the way off of the stud. Hold the upper tube in place loosely and using a 7mm socket with swivel, screw the stud into the alternator bracket being careful not to cross thread it. Loosely attach the tube to the IC.
Once you have everything lined up, put the rest of the SC top bolts in and start tightening everything up. Leave the IC for last. Don't overtighten the SC top.. 10 lbs of torque or less is about all you need. Then tighten the nut. Again, you don't need a lot of torque, 20 lbs should do. Then lastly even tighten the nuts holding the IC in place.
The big thing is keep everything loose until its all roughly in place, then tighen stuff up. If you removed the collar nut, tighten it before you fully tighten the stud nut on the bracket.
