how much water??

[NuNoos at aol.com]

Hey guys, gotta few questions for you. I just received my koyo radiator, and
I really need to find out how much water/coolant I need to buy (I live Phoenix
so its hot!). Also will i need to drain all my fluid to do this or just the
radiator? Should I run more than 1 bottle of water wetter?

Sorry for the barage of questions, but I'm supposed to be doing this tommorow
morning!

Thank you,

Mark
