Thanks Thomas - good call - I am referring to the coolant tank sensor - but
the T-2 sensor which you point out was also replaced...so your theory
continues to live.  I get it that the coolant tank sensor only identifies a
coolant level issue and not temperature - for some reason I connected what
you said about the coolant temp sensor to the coolant tank sensor - as that
was what I thought first when thinking about replacement parts.
