My early gauge has temp markings (FWIW) and right smack on 190 is where
it sits. Of course, I have a 190 degree thermostat, so that's what you'd
expect. Idling at a stop light the other day when it was 90+ it snuck up
a little, but goes right down once you get underway. So I think 190 is a
safe bet.
My 2¢...

Runs great,
looks particularly bad since some SUV clown backed into it.
If you're near Mountain View, CA,
it's the red one with the silver bootlid.
