rad and coolant

Sounds like you're talking Fruitliner radiator shutters to me...

Thermostats are made for the cooling system environment and are
cheap.  Figure out how to insulate and wrap a heating coil around the
pellet then drive with current.  They are good valves and
if the logic is correct there will be a built in failsafe. The time
constant is at least as fast as an iron block.

How would it work to put louvers on the radiator and open and close
them?  You could operate a small cylinder or bellows with a tiny
valve and oil pressure.  If the louvers were closed you would not
have the inefficiency of pumping losses (air) through the radiator
when maximum cooling is not needed
