Stupid newbie question

I use antifreeze for swimming pools it is made for pumps and plastic parts and rubber parts you will have to use distilled water to get the right amount of antifreeze for the weather you are in. As DaveO said not to use automotive antifreeze. Most of the welding ones are set for about 15 deg. F. Good look on getting things right.

That RV stuff has alcohol (or something...) in it though. I read the red, Walmart stuff, and it's says "Flammable". THAT can't be a good idea

I think the next, best, alternative is DexCool, diluted with distilled water, and also available at Walmart...
