No. The antifreeze has to be mixed with the water before the water freezes.
Most antifreeze has a chemical that freezes at a very lower temp than plain water.
I believe a 50 / 50 mixture of antifreeze and water freezes at - 34 degrees Fahrenheit
I BELIEVE that STRAIGHT ethylene glycol antifreeze freezes at ( 7 * Fahrenheit )
How could it be if it freezes. The word anti means against so it appears it is against freezing.
A 50 / 50 mix freezes at ( -35 degrees Fahrenheit / -37 degrees celsius )
Antifreeze also provides corrosion protection for the cooling system parts , head gaskets etc. ( until the corrosion additives in the antifreeze " wear out ") so even if you live in an area that never freezes it's a good idea to use a 50 / 50 mix of antifreeze and preferably distilled water Water expands when it freezes , so freeze plugs / expansion plugs are installed in an engine block to hopefully pop out and prevent the engine block from cracking
So that the fluids don't freeze. When a liquid freezes it expands this can burst pipes and tubes, the frozen liquid also blocks the circulation of that liquid so that it can not do the job it is supposed to do. Antifreeze contains alcohol and other substances that freezes at a much lower temperature than water.
60% water and 40% anti-freeze works better than, 50/50, unless it freezes often where you live.
During a hard freeze, if there is only water and no antifreeze in the motor of your vehicle: at best, the freeze plugs will burst or pop out; at worst, the block will crack.

In countries which have a winter season ALL cars should have the correct amount of antifreeze added to their coolant fluids. If this is not added and the fluid freezes the expansion of the ice will crack the engine block.
