Hello,

You can definately add water at any time and the vehicle water pump will mix the solution while you drive. If you have a siphon like a turkey batter take some coolant out of the resevoir and then add the water and drive the vehicle.

I hope this was helpful. Please provide a positive rating for my help today. Thank you.
