Freeze plugs are designed to blow out if the engine coolant freezes and then expands

( they are a " safety " device to hopefully keep the engine block / cylinder heads from

cracking ) Straight water freezes at 32 degrees Fahrenheit , but a 50 / 50 mix of

ethylene glycol antifreeze and preferably distilled water freezes at - 35
