Technical Go out for a trip with 1lt antifreeze only

[eolonano]

Hi there,
When I bought spare parts for my Punto, I forgot to buy 3lt of antifreeze.

I've only 1lt of Paraflu 11 at home.
Now I'm flushing the cooling system.
If tomorrow I want to leave for a long journey using 5lt of deionized water mixed up with 1lt of antifreeze, can I be sure enough against corrosion and boiling water?

even if you use tap water it will still take years to take any effect on engine, so if you are gonna put distilled/deionized water+antifreeze in later, just put tap water in for now

you need 4.2 litres

Just fill it with water for now, and then change to desired mixture when you have bought everything..
