Default Coolant question

I had my cam put in last night and the mechanic gave me some "pre mixed dex." Thats what he wrote on the bottle. That means it already has water in it? Also its ZEREX dex-cool antifreeze coolant. It is a redish color, thats good right? also this just goes in the lid that has "never open when hot" writen on it right, the coolant place? Thanks alot

50/50 just means its half distilled water, half coolant, will work fine, its cheaper per gallon, but you dont get as much coolant for the buck that way. I buy one gallon of pure Dexcool, and add it to a completely empty system, then fill with water till its full.
