As with many things, it depends. I was once in the car when my dad drove about 15km at highway speed, not taking any special care, before remembering that he’d drained the coolant system of his Saab 900 and forgotten to re-fill it. The engine was up to temperature by that point, but we stopped straight away, found some water, and filled it up, and no obvious ...
Water has a boiling point of 100c/212f at sea level. A soloution of 67% antifreeze to 33% water raises the boiling point of the mixture to 113C/235F. A mixture of 50/50 will cover most vehicles except for really cold climatic areas of the world. Anything less than around 40% antifreeze solution will allow cavitation of the water and corrosion of most of the ...
Yes, you can't just use pure coolant in a radiator. The coolant raises the boiling point of water, but without water it will not work well. Replace the coolant in your system with the correct mixture of water and coolant.
Typical engine coolant not only contains antifreeze but also corrosion inhibitors that deteriorate with age. It will always be better to know that something is OK rather than quess it is. We still check our engine oil level even though cars today use very little oil-don't we!
