i flushed my green out after my dexcool swap just to make sure what ever dexcool mixed in w/ the green was also out.....now should i do 50/50 or is using more green to water better or vise versa? ive been pre diluting it my self in the bottle by pouring half into another bottle and filling them up with water? also i cant get my heater core to open because its so damn hott out that my car wont blow heat with the hvac on 90* it still blows ac lol is there a way to open it otherwise? lemme know what i should do im gonna fill tonight....
