Subject:      Crazy Coolant Light Question
Content-Type: text/plain; charset=us-ascii

Larry,
     You are partial right and partial wrong.   The
light-sensor combination is sensitive to
electrolyte/ion concentration.   Pure distilled water
would make the light come on.   There exist some
amount of antifreeze which contains ion that will
allow current to flow between the two electrodes and
the light goes out.   Doubt that it takes much and if
you have very hard water you might not even need the
antifreeze.   The design is for the indication that
there is no fluid more than the kind of fluid but it
does give some indication of antifreeze concentration
when distilled water is used.   It is possible if your
coolant is right on this edge it could make the light
act crazy, particuliarly if your sensor is in need of
replacement.   regards gary

I disagree
common misconception
