So I am looking to get SCA in my cooking system. Previous owner definitely didn't do this, Told me he used standard "green" coolant. I can buy 64 fl oz of SCA at my local NAPA for about 20$. According to the label that's enough to initially charge 16 gallons of coolant. I'd like to do this but how do I know if the "green" coolant in there is compatible with SCA? Are they all? Also, because my system is already full, do I just drain about 32 fl oz out the bottom and pour SCA in from the top? Option two is to buy 4 gallons of fleetguard concentrate at about 10$ each. Opinions?
