Roger,
Antifreeze is not effective if it is not mixed with water in the proper
ratio. The manufacturers don't recommend using undiluted antifreeze for
this reason, and you know they would love to sell you more if that was
viable, but it isn't...Take a bowl of pure antifreeze and put it in
your freezer and see what happens....
