Believe me this is really fvcking with me.
As far as I can tell there is no hot line
The manual says to fill it to the cold level but doesn't really say where just a lame picture of the engine bay with an arrow.
If that's cold below the hose nipple level, how does it flow into the radiator when needed.
Edit****
Cool thanks FFDP, I'm on the same page.
My sharpie has made marks on the bottle for my preferred amount, roughly in the middle
I did have it blow out the overflow after filling it to the top of the line towards the cap.
