29 Model A Coolant

Walmart has distilled water, $1.00 gallon when I bought it last fall when changing antifreeze for winter

My radiator was low.....I just topped it off with "orange" coolant

Should I drain the whole system and go all "green" now maybe?

So after my deal with the leaky carb, it runs and doesn't leak but needs coolant, which is the best coolant to put in it. Thanks

runs and doesn't leak but needs coolantt

If the "doesn't leak" refers to coolant then this would worry me. The coolant must be going somewhere? Is there coolant in the oil (looks like a cup of coffee)? Are there bubbles in the radiator top tank while running? Is coolant dripping out of the tail pipe? Any of these think could point to a blown head gasket, or a crack in the head/block.

What does the container say about the "orange coolant"? Is it ethylene glycol?

Was using regular Prestone 50/50 mix, foaming big time and spitting out of radiator cap a bit. I know well enough about proper level, just under the baffle in the top tank.

Couldn't figure it out since I had a fairly good tight cap gasket and an unobstructed overflow tube. Someone on THIS SITE told me to try the Green Sierra type, so I did, a 50/50 mix as usual, never foamed again after 9 years now. Yes, it gets very cold here, no heat in garage. Works pretty dag-gone good.
