Anyone ever try this?
Using a digital multi-meter, remove your radiator cap and place the positive lead in your antifreeze. Connect the negative lead to the negative terminal of your battery. Read the voltage, 0.4 volts or less means antifreeze is okay. More than 0.4 volts means antifreeze should be replaced.
It is suggested that in severely neglected cooling systems, high voltage can basically turn your cooling system into a sort of battery, which can even effect engine electronics.
Note: This test has nothing to do with checking the effectiveness of your antifreeze. To to this, use an antifreeze hydrometer.
