Are you sure it's supposed to run like that?   I've noticed on my old Datsun 510
that the temp guage reacted the same way when the coolant level was low.

It sounds like it's simply a matter of getting a t-stat of a lower tempature,
say 180 degrees to replace a 190 degree t-stat.  Yours is probably sticking,
and since the things only cost a few bucks (plus the gasket) I highly recommend
you get it replaced *immediately*

*** REPLACE THIS LINE WITH YOUR MESSAGE ***
Ever since the pollution control standards have come out, I have found that
my new cars have been designed to run quite hot, evidently to reduce the
polluting effect of the motor.  The heigh temperatures have led to problems,
such as early deterioration of the hoses and other rubberized parts.
Therefore at the most convenient time, usually when the first thermostat
became defective, I have replaced the high temp thermostat with a lower
value one, 160 to 170 range.  The motor ran better, parts lasted longer,
etc.  It probobly was less efficient and more polluting, but I was unable
to detect it.   Anyway, you could probobly do the same thing with your
new car and have the same satisfactory results.
