Radiator overflow bottle Question.

I'm not convinced that damn thing is worth two cents. It doesn't seem to be "recovery," only overflow?? Which means you have to keep draining it

All you have to do is attach a hose inside to the inlet tube, that's what I did with mine, it works like a champ. Mine has a petcock on the bottom to drain it, now I don't have to use it.

But you're right, it is only a puke tank.
