Actually my Rad sticks out a 1/4" outside the case. It goes Rad, shroud, fan, pulling air into case.

Bleed the system of all AIR.

How I prep my system, is I take a 5 gallon bucket. Add my purple ice to distilled water. I usually use 2 gallons of h20.

First I put rad under water by itself. I then take a foot long tubing and while tube and rad is under water I put tube onto both barbs of rad. Then I pull out rad and shake air to top of the tube loop. Then I put rad and tube back under water, pull tube off under water and then put tube back on barb ends of rad under water and pull out. Shake again, make sure your shaking the rad w/ the tubing facing up, if no air present then you rad is free of air. Set that aside.

Then take the rest of your system, pump, water block, and tubing that at this point is ready to go, meaning it put together and clamped and put it under water in the bucket and run it and get rid of the air. Keep an eye on where the 2 end of tubing for the rad are. keep them together, shake water block a little to get any air out. When air is all removed, turn pump off, keep everything under water, hold on the 2 hoses for the rad with left hand, get rad and put it under water then remove the loop hose on rad hold the water in, then connect the 2 hosing for system to rad. Gently pull out of bucket and make sure neither one of those 2 hosing comes off of rad. Then clamp those 2 hosing on rad and your done.

One time one hose came off of rad and I had to start all over. man was I pi$$ed.

Oh well that how I do it. That way you have a system free of any air and it is bleed all the way out.
