looping coolant lines together

[gwarden]

Subaru fixed that on the forester so you couldn't mix up the radiator caps. They didn't put one on the radiator.

Notice that there is an air bleed hose from the top passenger side of the radiator to the "Engine coolant filler tank" (degas tank) Wayne's hose take cares of that getting the air out of the top of the engine.

I've read something about Wayne recommending a hose to help purge air from the system but can't find that post
Can anyone help me find it?
