- Forum: Water Cooling
To be honest I think you're over thinking this considering you've already committed to pulling it apart and cleaning the blocks and replacing the tubing. Me personally, I'd do just that, drain it, pull it apart and clean each part. Put it back together, I'd use X1 as coolant add (now that I've got it, love it), run it little while and then drain. Fill it again and enjoy my new, shiny cool system again.
