Custom loop isnt bleeding

1. Use a multiport reservoir top with a down tube in one of the 3 ports to result in a discharge point below the water line. This elimiantes spalshing and allows an inch or so of air space on top of the res to allow air to accumulate.

2. Air will accumulate at the highest point. ising a horizontally mounted radiator on top witj accessible top ports is a godsend.

Here's an image of rad installed and fans not yet . Those ports are about 42mm below the bottom of the top case grille.



I Installed a 40mm G-1/4 extension fitting and brass cap to extend above the fans which you can kinds see here (bad pic)



To fill and bleed it, I take off one of the caps and attach and extension tube. There's a funnel on top. The bleeding procedure it to fill the tube about half way and then close the valve. I put a book under the rear of the case so that all the air collects in the reservoir portion of the rad where the tube is. Air rises into the tube and fluid drops don to take it's place. I have about 2" of air space in the cylindrical reservoir at this point as anything that gets trapped in the res a) can't get out cause if the down tube and that is easy to bleed.



Here's pics of a drain port using a quick disconnect and the 3 port top i used on the res.




her some pics of the bleed at the reservoir





In the last pic, yu can see the down tube delivering water below the water line. In the closeups, that's the inlet in the foreground. In the background there's a riser that goes to a valve, then a 90 degree elbow and cap.

After all the bubbles are outta the lop and only thing left is getting the res level to about 1" from top, I fill the top tube just like before. Then i crack the valve above the res and slightly unscrew the cap. Then while watching the interior reservoir level, I crack the valve on the top tube and let fluid drain into the system till it's just where I want.

If I need to drain a teeny bit (never have), then I have a drain tube which attaches to the QD fitting under the bottom rad, also vaved by which i can let some out thru the 36" flexible clear drain tube.

Parts list in next post

And before ya ask ....

1. Yes, I did put in the pull fans so all rads have push / pull

2. No I still didn't finish sleeveing all the custom cables.
