Engine Coolant. What you running?

[grass doctor]

I use water from the arctic glacier it runs extra cold, triple distilled and some RMI-25---- FTW!!!!

If all you're worried about is corrosion, just dump some green in there and be done with it.

There's no magic to be found with oddball coolants in a car that sits.

Really? Than if that’s is what you would recommend I will do it. Thanks Earl. Not a mechanic just dangerous enough with my tools but I do play one on TV.

Peak Conventional Green. 50-60%
Water and a bottle of that RMI stuff.

I don’t buy it pre-mixed. Why buy water when I can mix it myself?

Since you're more north than me, I'd probaly do 25% green 75% water. Unless you want to look up the freeze points of coolant mixtures yourself. I was going to memorize the tables years ago, but that would have used up valuable brain space more suited for pr0n.
