temp
My 1978 F-100, 302, automatic, has a 180 degree thermostat. After the engine warms up and is running the temp gauge always reads a steady 210 degrees.
Is this wrong, or what it should be?
Thanks, CB3

The lower number on a T-stat does not mean it will run cooler. That is the opposite of what happens. With a 180 you will have an open circuit that never has time to cool. Try running a 190-195 and see if it stabilizes.

I think you need to check the actual temperature with a Infared temp gun to be sure of where you actually are. 210 is too high for a normal range. Also check your fan blade and shroud and how clean your radiator is.
