I wonder if Miller Industrial Supreme antifreeze/coolant would work, stock no 043 810. I use it in my TIG cooler. I bought the stuff from a local welding supply store and filled the radiator tank about 8 years ago. I never changed it (they recommend yearly). Your message prompted me to look in the tank and It looks maybe about 1/3 down from where I started. The cooler has a sight glass so I never checked the actual level, I just make sure I see flow when I start welding. The system is somewhat sealed but not perfectly. The label says: "may be used in any system where aluminum is NOT in the coolant path, but I think my radiator has aluminum in it. The guy at the store insisted it was OK. So It seems to be working and looking fine. There is no mold or stuff floating around in the tank and the fluid is still clear. The welder has been in the un heated part of my shop for at least 7 years. Now that my shop is bigger I moved the welder to the heated part so technically I don't need antifreeze anymote. The back of the label says it is a low conductivity ethylene glycol base. I use it full strength and it is rated to -37F
