Mike,
First: the water that you see coming out of the exhaust pipe is
perfectly normal.
One of the by products of combustion is H2O and it is normal to see this
before the car gets to operating temperatures. If you aren't replacing
coolant, you are not loosing any.
Second: the gauges on these cars are getting old and probably weren't
that accurate when new. You seem to be keeping a close eye on things
and you are right to do this given the age of the car. If your cooling
system seems to be working fine, it probably is, but keep a close
watch. Unexplained changes in temp are what should concern you. Make
sure the fan belt is tight and in good condition and the hoses are
sound. It is not a bad idea to change these as a preventitive measure
every few years and keep the old ones in the trunk as spares along with
some pre-mixed anti-freeze.
