Blueprint 408 cooling system questions.

Yep. That is the MINIMUM engine temperature. If you run a 180 thermostat and the car is constantly at 195 that tells you the cooling system will only maintain 195 under load.

You could drop a 120 degree thermostat in there (if there is such a thing)and it would STLL be at 195 under load.

Yup and no matter HOW HARD you try to tell people, they WILL NOT listen.
