Antifreeze

[Shortyrock]

I’ve been in Florida the last 35 years but traveling cross country to cold weather . Do I need antifreeze in my radiator during my travels

All vehicles with a radiator need at least 50/50 protection antifreeze year around no matter where they are located.

How many radiators have you had to replace in those 35 years from corrosion leaks?
If they had no antifreeze in them.

Is this a serious question?
You need 50/50 anti-freeze and water in your radiator to protect against corrosion and boil over in hot weather. It should be obvious that you need it for any temperature below freezing.
