I tried the bottle trick - it didn't work. It stopped the water flow (antifreeze) from leaving the filter housing as it got sucked up to the top.
Maybe I need to have the bottle upside down? I ended up just taking the bottle out and using an extra 12 ounces of antifreeze, but I'm curious what others have found out.
