Re: water/antifreeze

The point to make is that after water reaches freezing temperature it expands as it get colder than freezing.

I use regular old 50/50 pre-mixed antifreeze in my model T ford and my 54 Packard.

The only concerns had to do with aluminum parts but I am led to believe the current stuff is safe with anything.

There's the story of a friend who had an all original, low mileage 1932 flat-head ford V8 roadster and he was showing off his newly painted garage floor and left the car outside for the night.

It cracked both heads.

Myth #1 Freeze plugs will protect the block. They are actually there for the casting process and are not intended to protect anything. They will pop out but usually the block is ruined.

Repairing a cracked block is extremely difficult and expensive and then you have to do a total rebuild of the engine.

Myth #2 draining the cooling system will protect it. Maybe but I want to know there is no water trapped in a tight space like a pump or something.
