Putting coolant in a 1997-2002 Holden VT Commodore?

[Stephanie47]

I'm using my boyfriends VT while he is away, am fairly sure it's a 99/2000 model, but is definitely between 1997-2002. And I need to refill the coolant resevorir. I'm using Nulon 100% concentrated coolant in it, because that is what he has always used but the bottle it is in has lost the directions on how to use it.. Do I have to mix it with water before I put it in the coolant resevoir? And if so to what ratio?

Thanks in advance.

A 50/50 mixture of coolant/distilled water should do the trick!
