Check out Dave Swingle's pertinent article from website: http://www.dmcnews.com/Techsection/waterpumpDMC3.html Really FYI, since he too recommends buying pump with pully already installed. Is what you're paying a little extra for (sometimes doesn't pay to reinvent the wheel). Fascinating procedure though, eh? When my time comes I'm planning to let experienced installer do it as well. Worth every penny?
