Hobby Racer,
I love you plumbing.
Great job, keep up the good work.

To make my cooling system self bleeding. I have 2 small hoses coming back to the expansion tank.
1. From the high point off the engine, same as you. I put a pill in that hose with 1/8" hole in it. This allows air through quickly but limits much fluid going through.

2. Small Hose from top of radiator, kept as high as possible, back to the expansion tank.

I teed these 2 hoses together before attaching to expansion tank.

Bob, what did you use for the pill? Also, do you have a line installed at the bottom of the expansion tank for the engine to pull fluid back into the system?

I took a 5/16" bolt and cut 1/2" long piece out of the shank. The drilled 1/8" hole the long way.
I'm using the standard wrx expansion tank. The bottom hose out of that tank goes to the suction side of the water pump.
