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..

Yes, this will test your coolant while it is cold.

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.

Works Well

Very easy to use, seems to be fairly accurate. Measuring brand new 50/50 mix of Ford "Gold" coolant, this device seems to indicate less freeze protection than what is advertised on the back of the bottle, but still well within reason. I suspect the number on the bottle is just using a different measurement standard, or perhaps it's user error on my part. Regardless it's perfect to monitor the state of my cooling system, I just compare it to the brand new coolant as a baseline.

Very nice

I was expecting one of those pee pee syringes that fit in your shirt pocket. It is a full sized professional grade tool that you can actually read and use. Love it.
