I'm trying to use a wine hydrometer but obviously that reads actual specific gravity, not coolant freezing temperature. I may have to just buy some new coolant concentrate and test it at different dilution ratios.
Can you check the accuracy of your instrument by using plain water? I bought the cheap small ball float test and plain water floated three balls! WTH?
What coolant?
