Iggy, pull a sample of your coolant and pop it in the freezer. There's
a decent chance that the soluble oil will drop the freezing point enough
for you.

No point in solving a non-existent problem.


Seems like a great idea. I will definitely try.

Two bits of advice.

1) Don't put it directly in a rigid container -- even a soft
plastic bottle, because of the chance of it freezing, breaking
and possibly contaminating the food in the freezer.

So -- put it in a Ziploc baggie -- only about 1/4 full to give
plenty of room for expansion.

2) Because some anti-freezes taste sweet, and have colors
attractive to small kids (and maybe your coolant will as
well) -- put the baggie in a child-proof cap container, which
could be loose in a large pill bottle.

After all -- you have little kids to worry about.

For that matter -- label it so if your wife pulls it out, she
will know what it is.

Good Luck,
DoN.
