Coolant electrolysis, Coolant Voltage
It's been suggested to me by someone in the field to do a coolant flush sooner than recommended to prevent various engine & parts from internal corrosion. A simple test is to stick a volt meter across the neg terminal and coolant. Ideally there should be zero (0) voltage across. In reality this is not the case, but as coolant ages its electrolytic properties increase. Left uncheck, the coolant itself can become a battery and eat away at the various surfaces it's in contact with.
On my car at ~16K miles, 3 1/2 yrs old I got a reading of .23 V. From some online research done this is within the acceptable range. Goal is to do a drain/fill sometime this summer which should refresh some of the coolant.
Thoughts?

You learn something new every day!
Would be cool if you can light a small LED with this new found power source haha

Motorweek was a contributing factor . This was actually suggested to me sometime last year but I never got around to it until now.
I should see what our brand new honda measures out at. Car has less than 500 miles and is really practically brand new.
What values are others seeing?
.2 - .3V isn't really enough to drive an led as those typically need ~2V. If the coolant is producing that much, you've got _big_ problems.
