Hi again,

Regarding anti-freeze, is it safe and OK to just add 100% anti-freeze if the coolant resevoir is slightly low and you want to fill it to the max bar level?

Someone on IRC said pure anti-freeze will damage the head gasket. But another person told me it's OK to add pure anti-freeze to top off the resevoir. By the way, it's summer here.

Thanks guys.

I think I'd still mix it 50/50. Even for just a little bit.
