Q: What does reading #6 "Not Safe" mean?

This will sound crazy. Too much undiluted antifreeze will not lubricate the water pump and the corrosion inhibitors will not perform to their full potential..Full strength antifreeze ( concentrated) needs to be mixed 50% with water. Will 6 ball freeze? ? Nope.but drain some off add some water pumps and head gaskets are expensive..

Q: The directions say "count the floating balls" do they have to be floating at the top or is just off the bottom to be good enough to be counted floati

As long as it floats it counts. The discs don't need to go all the way to the top.
