Phil,
The first thing to do is to remove the coolant level sender
and clean the probes with some steel wool or fine sandpaper
to remove any corrosion. The water/coolant ratio shouldn't
really matter that much I ran plain water with no anti-freeze
in mine for a couple days and the coolant light worked fine.
Clean probes are happy probes....
