Greetings,
Since I seem to have plenty
of cooling capacity, I'm thinking that it may be time to add some coolant to my
distilled water. Since I live in Florida, I don't need all that much
freeze protection, so I'm doing it mostly for the corrosion protection, and pump
lubrication. My goal would be to use as little coolant as possible, to get
freeze protection down to maybe 20 degrees. Less coolant also means better
heat transfer, which is another reason to use as little as possible.
I could swear that I've
seen a chart that tells the percentage of coolant vs freeze level, but now
I can't find such a chart. On the manufacturers pages, they seem to
want you to stay between 50 and 70 percent coolant. I never saw
them recommend less than 50%, and one page even said that you needed at least
50% for corrosion protection.
I could certainly run
distilled water, and water wetter in the summer, and 50/50 mix in the winter,
but I'd like to find one mixture that would work year round, just in case I ever
manage to go more than a month or so without having to drain the water for some
reason. Hey, it could happen :-)
Anyway, the real question
is- what is the minimum percentage of coolant that will protect down to 20
degrees, and will this provide all the corrosion protection, and lubrication
that the engine needs?
Thanks,
